The invention relates to the field of pulse technique based on magnetic concentration of energy, i.e. the rapid compression of the magnetic flux by means of a metal shell, dispersed shock wave explosives (he). This system can be used for the formation of high-current and high-voltage pulses, to create a directed flows of radiation (x-rays, neutrons and the like) and the acceleration of bodies up to high speeds. Thus the system can be used as an experimental tool to study the physico-chemical properties of materials under extreme conditions.

A device explosive pulse power system, see the proceedings of Megagauss and megasperma pulse technology and applications/ edited Vchernysheva, Vdelete, Linfatico - Sarov. VNIIEF, 1997, Fig.2a, str.

The device consists of a helical explosive magnetic generator (SVMG)containing the Central tube and coaxially located with the spiral, the main explosive charge in the Central tube, the isolator output SWMG with coaxial cavity (inductive drive SWMG). Inside the cavity posted by shaper jets. In the center of the cavity is extended Central conical explosive charge with the focusing system, inside a metal tube which has Zilin the historical explosive charge, end in contact with the end face of the main explosive charge. The load is shunted by a coaxial metal foil (torn conductor) of the inductive storage SWMG.

The system works the pulse power in the following way. After creating the initial magnetic flux in SWMG and inductive drive SWMG is the initial compression of the magnetic flux. This compression of the magnetic flux produced in the metal circuit SWMG by deformation diverging shock wave from BB, with a gradual decrease in the size of the cavity, resulting in the displacement of the magnetic flux in the insulator, located at the exit SWMG, and a coaxial cavity, forming an inductive drive for SWMG, and therefore also to increase the magnetic energy. At the end of the work SWMG is the removal of magnetic energy in the load is shunted by a coaxial metal foil inductive storage VMG. Foil sharply changes its resistance in the process of destroying its dielectric jets formed by using a shaper jets placed inside the cavity. The formation of jets begins after full undermine located inside the cavity, the extended Central conical explosive charge with the focusing system. A necessary condition that all the external surface of this charge detonation was at the same time without delay. The main function of the focusing system consisting of metal tubes filled cylindrical CENTURIES, and is in this. Expanding the products of the explosion of the pipe when the undermining of the end of the CENTURY, completing this focusing system, directly from the main explosive charge is changing in time tapered profile and provides this gradual initiation of the internal conical surface of the explosive charge to the entire outer surface of this charge detonation was at the same time. The removal of magnetic energy in load with increasing power is in the process of diffusion of the generated magnetic field generated through the gaps in the outer coaxial metal foil (membrane), which deteriorates dielectric jets shaper during the entire time of its operation. Thereby is achieved a substantial increase in the resistance of the foil. In addition, there are some additional strengthening energy in the load due to the deformation of the detonation products of a cone charge accumulation circuit.

To increase the power of the generated pulse and efficient energy transfer to the load necessary to fracture foil occurred simultaneously throughout the length and diameter and as quickly as possible.

The disadvantage of this device is disabled the output in practice fully comply with the necessary requirements. Execute them, as mentioned above, depends on the quality of undermining the conical explosive charge, which should provide a focusing system. The process of initiation is influenced by a number of factors: raznorodnosti in the materials of shells and EXPLOSIVES, the presence of misalignment at the location of the focusing system, thickness, etc. All this affects the speed and simultaneity of the process of rupture of the foil and, as a consequence, the explosive power of the pulse system. In addition, significant main disadvantage of this device is "conservative" using a variety of dimensions of the metal foils in the inductive storage with the purpose of formation of various voltages. In theory on the physics of the phenomenon is possible, and engineering an embodiment of the device is problematic. As undermining the focusing system comes directly from the main explosive charge, using, for example, more elongated metal foil in inductive drive for SWMG requires radically change the entire focusing system. And in some cases this may not be possible in predetermined radial dimensions.

Also known device explosive pulse power system, see the proceedings of Megagauss Magnetic Field Generation and Pulsed Power Applications"/Ed/ M/ Cowan and R. S. Spielman - New ork. Nova Science Publishers, 1994, fig.1p., 481-488.

The device consists of a source of primary power supply in the form of a spiral VMG (SVMG), inductive drive for him, which is line with isolator at the output of the spiral generator. The device also includes a multi-element cassette disk explosive magnetic generator (DMG)containing cassette with disc explosive charge, the end flanges and the Central tube, where with a given step are arranged coaxially with her cassette CENTURIES. Inside the tube there is an auxiliary explosive charge, the focusing system (node routing detonation, providing undermining auxiliary explosive charge inside circumference strictly in specified places), the blasting cap is installed outside of the generator at the end of the focusing system on the load side. Load outside of the disk generator.

Works explosive pulse power system as follows.

In the device excretion of magnetic energy in the load is directly in the process cluster disk VMG, in which the accumulated energy from SWMG. As the disk generators are the most current and speed, the output is able to generate high power, provided, if there is simultaneous undermining all disk charges in magazines. In addition, the aim is nashego exacerbation front of the current pulse in the load can output DMG to sexonthebeach foil, which many times will increase its resistance as a result of electrical explosion from flowing through it of an electric current. In this case, conditions will be created for switching (flip) the current in the load for a short period of time and get even more powerful pulses of electromagnetic energy.

The disadvantage of this device is the difficulty in providing simultaneous multi-point exit detonation in a focusing system when using the explosive line wiring. To implement multipoint detonation, you need to create a multi-tiered difficult-branched path for explosives in the site layout. The difference output of the detonation occurs because the incoming differences in the geometric dimensions of the ways to undermine and some differences in the physico-chemical properties of EXPLOSIVES on these long routes. In addition, another significant disadvantage is that you can only use a certain number of cartridges in DMG in predetermined radial dimensions of the focusing system. This is because the creation of more outputs detonation is limited by design features explosive delay line.

Closest to the claimed system is a pulsed power, see proceedings of the conference "hydrogen the MT of high energy density", Ed. Gasparov - Novosibirsk: in the Institute of hydrodynamics of them. SB SB RAS, 2004. - report New research opportunities liner implosion when the currents 15-20 MA: creating a diagnostic stand with removable source of pulsed power", Fig.1 and Fig.2, str-233.

The device prototype system pulse power includes sequentially placed explosive magnetic source of primary energy with output isolator and at least one explosive device with axial system of initiation of the explosive charge, which contains the power supply, the electrical input and wiring to undermine the chain of electric detonators.

As explosive magnetic source of primary energy is used helical explosive magnetic generator SWMG consisting of coaxial outer helical conductor and the inner conductor with an explosive charge and an isolator at the output. As the explosive device to the axial system of initiation of the explosive charge is used multiple disk explosive magnetic generator (DMG), containing the elements of the disk with the explosive charge, the end flanges and outer coaxial conductors.

The operation of the initial compression of the magnetic flux is first carried out in the cavity SWMG pull him into the cavity of an explosive device. If C is the concluding work SWMG is undermining chain electric detonators, initiated in the Central part of the disk charges. The electrical input to undermine the chain of electric detonators carried out on the side opposite from SWMG. When working DMG over a short time period, which is determined mainly by the time of the detonation disk explosive charge, is fully deformation of the contour, which achieved a significant increase in energy. A little time and a significant increase of energy provides, in turn, generate a powerful momentum. In addition, to further exacerbation of the front of the current pulse in the load often the output DMG continuum foil, which greatly increases its resistance to the flowing through it of an electric current. Thereby is achieved favorable conditions for switching current to the load for a short period of time and get even more powerful pulses of electromagnetic energy.

The disadvantage of this device prototype is impossible to get from a vacuum substantial amount of output radiation at the current implosion of the load, which, depending on the tasks are products of electrical explosion assemblage collected from thin wires, foils, gas mixtures, etc. as a result of implementation of the undermining of electric detonators from the output of the radiation electric input is Travego device is located within the Central part of the compressible load, occupying part of the volume. The strength of the electrical input is designed for operating voltage of the power source, in the tens of kilovolts. To protect against this voltage, the overall radial dimensions of the gland shall be not less than a few millimeters. This, in turn, interferes with symmetry reduction and the achievement of maximum compression, such dynamic loads. With proper implosion of such assemblies must be formed pinch of diameter about 1 mm, which radiates most of the energy range up to 1 Kev. In addition, when the output of the radiation flux generated from Z-pinch will have a significant perturbations and deviations from the specified direction of propagation due to the presence of electrical input, which is a foreign body in this volume. In turn, this will affect the correct interpretation of the results of the impact of such directed flows of radiation on the object under test, for example, in experimental studies of the physico-chemical properties of materials.

This invention solved the problem of creating a device that would allow to use the powerful impulses directed flows of radiation for decision research, experimental and applied tasks.

The technical result, the achievement of aemy when solving this task, is stability results in increasing the reliability of the claimed system and increasing the power level of the pulse by reducing distortions and deviations from the predetermined direction of propagation of output pulses threads radiation at undermining electric detonators from the isolator at the output SWMG.

This technical result is achieved by the fact that, compared with the known pulse power system comprising sequentially placed explosive magnetic source of primary energy with output isolator and at least one explosive device with axial system of initiation of the explosive charge containing the power source, the electrical input and wiring to undermine the chain of electric detonators, in the inventive system pulse power electrical input is located between the explosive magnetic source of primary energy and an explosive device. In this case, the electrical input is made in the form of at least one tubular dielectric element with the conductor and with a tight installation in a through hole made in the output isolator explosive magnetic source of primary energy, and has a protruding portion on the outer surface of the output of the isolator. In addition, the pulse power system above and below the output isolator stage is niteline installed elastic ring seals, and on the outer surface of the tubular dielectric element and on the inner surface of the through hole output insulator threaded connection, to ensure in this place a very tight fit, using additional insulating elastic gasket and a liquid or pasty dielectric filler. As the explosive device used or explosive driver current pulse, or multiple disk explosive magnetic generator, or both disk explosive magnetic generator and explosive current driver.

The proposed new layout solution, where the electrical input is located between the explosive magnetic source of primary energy and an explosive device in the form of at least one tubular dielectric element with the conductor and with a tight installation in a through hole output isolator explosive magnetic source of primary energy. The absence of electrical input load side ensured the stability of the device by obtaining the maximum output radiation. When the displacement of the magnetic flux in the explosive device experience significant voltage applied to the isolator at the output explosive magnetic primary source of energy (for example, in CWMG). As the working cavity SWMG izgotavlivaet is sealed due to the elastic o-rings above and below the isolator at the output of the helical explosive magnetic generator (SVMG), you can fill elektroprogram gas. (The same strip installed at the entrance SWMG.) Electroprecizia gases or their mixtures (at atmospheric pressure or above) allow you to use the isolator at the output SWMG with significantly shorter in the workspace, where the compression ratio of the magnetic flux of the spiral generator. This is because the breakdown on the surface of the insulator that separates the coil from the pipe, when filling the cavity, for example, sulfur hexafluoride (SF6) at atmospheric pressure, will occur when large voltage approximately two times. Thus, it will be possible to significantly reduce the length of the insulator that covers the spiral, and, consequently, to reduce the loss of magnetic flux remaining in the thickness of the insulator, at the final stage SWMG. Since the electrical input is made in the form of at least one tubular dielectric element with the conductor and with a tight installation in a through hole made in the output isolator helical explosive magnetic generator, the conductor shall be insulated from the relatively large breakdown voltages (tens of kilovolts). Electrical inputs can be done several with a uniform spacing of the holes around the circumference of the output of the isolator. On the outer surface of the tubular dielectric element and the internal p is the surface of the through hole output insulator threaded connection, which, when the tubular dielectric element with additional insulating elastic lining filled with liquid or pasty dielectric filler. This allows to achieve high electric strength in this place. The protrusion of the tubular dielectric element outside of the output of the isolator eliminates a break from the stress generated when working SWMG, inside the tubular hole with a spiral to the Central pipe. The output conductor through the thickness of the insulator does not require sealing, since the sealing SWMG already provide rubber gaskets installed at the beginning of the insulator. Thus, there shall be a separation of the total system pulse power on sealed and unsealed volume, which makes it relatively easy to use any explosive devices to the axial system of initiation of the explosive charge without alteration of the purpose of sealing their volume. Alteration in some cases may lead to a significant change in the design of an explosive device.

All of these conditions: reducing the length of the insulator located within the explosive magnetic source of primary energy; creating a reliable electrical input isolator with close elektroprovodnyi characteristics corresponding integral and is olateru; sealing volume SWMG allow to increase the output energy to the load, to increase its capacity by increasing the pulse current and voltage, to provide directional stable impact and versatility of the system pulse power with virtually any an explosive device with axial system of initiation of the explosive charge.

At least one explosive device 5 to the axial system of initiation of the explosive charge 6, which contains the power supply 7, the electrical input 8 and opening 9 to undermine the chain of electric detonators 10. Electrical input 8 is located between the helical explosive magnetic generator 1 and an explosive device 5. It is tightly installed in a through hole made in the output isolator 4 helical explosive magnetic generator 1, and can be installed in a through hole made in the Central pipe. The electrical input is made, at least in the form of a single tubular dielectric element 11 with the conductor 12, in an electrical circuit which can be installed in the spark gap 13 and which is connected to the middle detonator 10. The tubular element 11 is outside the spiral, and the other end located in the interior of the Central tube 3. In the figure shown embodiment, when the explosive device 5 used multiple disk explosive magnetic generator is connected to the load 14. On the outer surface of the tubular dielectric element and on the inner surface of the through hole in the output insulator threaded connection 15. Its electric strength security is as tight fit, additional insulating elastic strip 16 and a liquid or pasty dielectric filler. In addition, above and below the isolator at the output of the helical explosive magnetic generator installed elastic ring seals 17.

In the example implementation of the system pulse power as explosive magnetic source of the initial energy of the selected helical explosive magnetic generator with the internal diameter of the helix 200 mm Output isolator made of kapron brand H1 with a tapered inner part. The maximum thickness of the insulator 2 see as an explosive source with axial system of initiation of the explosive charge was used a high-speed multiple disk generator with a diameter of 240 mm and an effective working time ˜3 μs and output energy in megajoules range. Dielectric tubular element electrical input was made from caprolon with an outer diameter of about 20 mm To the place of its junction with output isolator were applied voltage ˜50 kV, and the breakdown was not observed. When conducting an explosive experiment, the pulse power system has worked steadily and in accordance with the standard mode.

Does this device as follows. Volume SWMG filled electroprocessing gas. In the circuit spiraling the explosive magnetic generator creates a primary magnetic flux. At the time of its maximum is undermining at the end of the explosive charge 18, which is located in the Central tube 3. By the end of the work SWMG is undermining chain electric detonators 10 from the power source 7. If in the circuit of the conductor 12, which is located in the tubular element, will be installed arresters 13 (not less than at least one of a spark gap, its parameters must be configured on the breakdown voltage Updefined, proceeding from the condition Uswmg≤Up<UFewhere Uswmg- output voltage SWMG (˜35 kV), a UFe- voltage power source 7. The second conductor 19 of the power source 7 is connected to the circuit wiring 9 to undermine the chain of electric detonators 10 in place out of the spiral. The electric detonators separated from the internal metal elements 20, 21, deformable during the blasting EXPLOSIVES 6, a sheath of dielectric material 22. (In case you used film insulator.) The shell 22 of dielectric material avoids breakdown upon actuation of the power source 7 in place of the supply wire 12 to the electric detonator. This provides the desired current pulse directly in the circuit wiring 9 necessary to undermine the chain of electric detonators. Undermining chain electric detonators 10 causes the simultaneous initiation of all disk charges 6, the village is e which starts working disk explosive magnetic generator 5. The displacement of the magnetic flux in the load 14 is fast, and that generates a powerful energy boost. When the current implosion of the load, which are the products of electrical explosion of thin wires in the evacuated volume, and gets the directed flows of radiation.

As the amount of load in comparison with the prototype no electrical input having a radial size of a few mm due to the lack of dispersion and contamination of plasma formations in the fixed interaction with foreign body can achieve compression of the pinch to the minimum size (in the order of one mm) at the collapse load and, consequently, to obtain reliable operation and at least one order of magnitude increase of the radiation power.
