The invention relates to particle accelerators and can be used for the irradiation of fluids, gas, water-gas, and other mixtures, in particular, for the irradiation of natural gas.

A device for irradiation, which is intended for the irradiation of liquid media (patent Germany 2258393 declared in 1972). The device includes an accelerator of charged particles, the camera scanning beam device scan beam, the pump feeding the liquid into the casing, and a funnel-shaped surface inside the housing, on the inner surface of which flows in a thin layer irradiated by the accelerator liquid. Luggage scanner beam is made funnel-shaped and has an outlet box having an annular shape. The plane of the outlet ports parallel funnel-shaped surface, on which flows the fluid around the entire circumference of the edge of the cone. The end surface of the vacuum chamber is made in the form of a cone. The cone is directed into the chamber (vacuum), increasing the rigidity of the vacuum chamber and reducing the volume of the vacuum chamber of the accelerator. Accelerator set the target fluid around the perimeter of the drain to achieve the same results exposure.

Closest to the proposed solution to the irradiation device is a device for irradiation by accelerated electrons (RF patent 1828380, N 05 N 5/00, 1996), containing the electron accelerator, the vacuum electronproton, pulse switching electromagnet, the winding of which is connected to the generator of bipolar current pulses, and the current generator electromagnetic scanning sweep. Electronproton connected with the vacuum chamber of rectangular shape, on the opposite wall which has two outlet ports, closed by a thin foil. Parallel to the outlet Windows of the vacuum chamber has two permanent magnet. Field of these magnets rotate electrons on the 90oand input them in the irradiated object at an angle close to 90o. The final choice of the window and scanning electron along the window performs switching electromagnet. Feature of the device is that the deviation of the scanned electron (i.e., the irradiation field formation) occurs in the marginal fields permanent deflecting electromagnets. Due to the small remove them from each other as a result of their superposition of magnetic fields in the plane of symmetry of the device, the magnetic field rachitele deflection of a beam of accelerated electrons for that he was in one or the other outlet box.

Known devices for irradiation by the Federal Republic of Germany patent 2258393 solves the problem of exposure of liquid and gaseous environments, however, the device has a complex structure outlet ports, is difficult to obtain a vacuum-tight connection of the foil outlet ports with vacuum chamber of the device, since condensation occurs on curved surfaces and around the entire circumference of the conical surface of the camera scanning beam.

Using known solutions for RF patent 1828380 you can solve the problem, however, the increase in power output for the foil outlet ports, hampered by the fact that we cannot increase the length of the camera scanning beam to a large value due to the fact that the angles of deflection of the beam becomes very small, while increasing the distance between deflecting the beam with the axis of symmetry of the magnets leads to a decrease in the utilization rate of the beam and increasing the size of the device.

The main problem solved using the proposed device exposure is the increased power of the accelerator, derived for the foil outlet ports, simplifying the design.

The invention consists in a device for the irradiation of the accelerated electronenergy bipolar current pulses, the current generator electromagnetic scanning sweep, vacuum chamber with exhaust Windows located on the generatrix of the surface of the vacuum chamber. In this device, the vacuum chamber is made in the form of two prisms, one of which end with the number of faces of three or more connected with the outlet Windows on the end faces of the prism, and the vacuum chamber connected to the working chamber into which is fed the irradiated environment. In the particular case of the implementation of the device, the flow direction of the irradiated medium counter to the motion of the accelerated electrons emerging from each outlet ports located on different sides of the vacuum chamber, outlet ports on the sides of the vacuum chamber can be across and along the edges of the vacuum chamber, the scanning beam at the outlet Windows can be sequenced from a window on the verge of 1 to open on the verge of N, and so on, or at the Windows, lying on the two opposite sides, with the subsequent transition to Windows on the other two faces, and the number of devices in the scan beam can be more than one, the angle of entry of electrons in the foil outlet ports, the point symmetry of the outlet box, close to the 90oor equal to him.

The technical result, which can be pochna, the simplification of the device configuration, the possibility of a process with different modes of exposure, and the possibility of exposure to different environments with separate feeding them into the radiation zone.

In Fig.1 shows a General view of the device for irradiation with vacuum chamber made in the form of a tetrahedral prism and the end of the tetrahedral prism with 3 outlet Windows on each face end of the prism located in the plane of the end faces of the prism.

In Fig.2 shows an example of this device with a vacuum chamber made in the form of a tetrahedral prism and the end of the tetrahedral prism with 3 outlet Windows on each end face of the prism, arranged at an angle with respect to accelerated electrons close to the 90oor equal to, the point of symmetry of the exhaust window.

In Fig.3 shows an example of this device with a vacuum chamber made in the form of hexagonal prisms and end of a hexagonal prism with final Windows on each face end of the prism along the axis faces the vacuum chamber.

Device for radiation consists of an electron accelerator 1, elektroprovoda 2, the switching electromagnet 3 with the excitation winding 4, the generator of the bipolar pulse is received prisms 8, 9. Prism 8, 9 are connected bases. Prism 9 end, on its faces 10 are arranged outlet ports 11 of the vacuum chamber 7, with the feeder 13 and output devices 14, 15 irradiated environment. The working chamber 12 has channels 16 for feeding irradiated environment to the exhaust boxes 11. Number of channels 16 is equal to the number of end faces of the prism 9. The channels 16 have walls 17, 18, forming a stream environment prior to graduation Windows 11. Each channel 16 has its output device 15 and the total, located on the axis, the output device 14.

The device operates as follows. The electron beam generated by electron accelerator 1 is directed magnetic field winding 4, which is located on the magnetic circuit of the switching electromagnet 3 and connected to the generator of bipolar current pulses 5, on one of the outlet window 11 of the vacuum chamber 7. The same excitation winding 4 is connected to the current generator scanner 6, which performs the scanning beam at the outlet box 11. After changing the polarity of the current pulse in the excitation winding 4 or its magnitude, the electron beam changes its direction and flows to the outlet box 11 on opposite end faces of the prism 9 of the vacuum chamber 7, or Papagena adjacent faces of the prism 9 of the vacuum chamber 7, the electron beam hits by switching on the second switching electromagnet 3, which produces a generator of bipolar current pulses 5 (Fig.1). The second switching electromagnet 3 in relation to the first rotated 90othat provides a transition beam with a pair of end faces of the prism 9 of the vacuum chamber 7 to the other pair of faces. At the same time to supply the second switching electromagnet 3, in the particular case of implementation of the device needs to have its own generator of bipolar current pulses 5 and its current generator electromagnetic scanning of the scanner 6.

When the position of the exhaust window 11 across the axis end of the prism 9 at an angle of 90oto the beam (Fig.2) a device similar to the above, but the characteristics of the device improves (decreases the path length of the electrons in the foil outlet ports, simplifies the design of the outlet box, and so on).

In the case of performing the vacuum chamber 7 and the face of the prism 9 with six faces (Fig.3), the third pair of faces, the electron beam will fall after turning on the third switching electromagnet 3, which will previously worked generator bipolar current pulses 5. Each of the three switching electromagnets 3 in relation to the other STS, you want your generator bipolar current pulses 5 and the current generator electromagnetic scanning of the scanner 6.

The irradiated medium is fed through the feeder 13 into the working chamber 12 and 16 channels routed to the exhaust boxes 11 (arrows in the drawings indicate the direction of motion of the medium). Channels 16 and sides 17, 18 form the flow of the irradiated environment each of the outlet boxes 11 counter to the flow of electrons, which ensures complete absorption of electrons irradiated environment, and not the structural elements of the working chamber 12 for a flow environment. In addition, the proposed scheme of the fluid increases efficiency and simplifies the device for irradiation, because it eliminates the adjustment of the electron accelerator 1 (change of accelerating voltage, beam current to obtain maximum efficiency of the device) when the change in the density of the irradiated environment, which may occur due to changes in the ratio of substances in the irradiated medium (e.g., ambient humidity).
