The invention relates to the field of accelerator technology and can be used as an injector of dust particles for subsequent accelerator system.
Known the morning side of the intermediate electrode, charging chamber formed by the outer side of the intermediate electrode and the housing of the needle (Article: Fechtig H., Grun, E., Kissel J., Laboratory simulation. Charber 9, M. P. InstituteKernphysik, 69, Heidelberg 1, FRG, 1989). The disadvantage of this source of charged dust particles is the penetration volume of the vacuum chamber uncharged particles.
The closest analogue is the source of charged dust particles, consisting of a hopper chamber formed bunker electrode and the inner side of the charging electrode, the charging chamber formed by the outer side of the charging electrode and the housing of the needle. (Akishin A. I., Novikov HP equipment and Technique of simulation testing of materials for spacecraft. - M.: Izd-vo Mosk. University, 1990, 90. (page 80)).
However, he has a number of disadvantages: in General stream of dust generated by this injector, the number of particles that have close to the maximum charge will not exceed 1% of the total number of specks of dust.
The task: to develop a source of charged dust particles, with a large percentage of the particles close to the maximum charge to the General flow of dust particles.
This object is achieved in that the source of the charging chamber, according to the invention, between the charging electrode and the housing introduced an intermediate electrode and an intermediate chamber formed by the casing and the outer surface of the intermediate electrode, and the hopper chamber formed by the casing and hopper electrode, the charging chamber is formed in a charging electrode and the inner surface of the intermediate electrode.
The invention is illustrated in the drawing, where Fig.1 shows a device (front view in sectional view), Fig.2 is a top view.
The device includes a housing 1, in which the circumference is made bunker camera 2, placed in them bunker electrodes 3 in the cavity of the housing 1 has an intermediate electrode 4 with a spherical inner surface, the cover 1 has a charging electrode 5 is placed on the needle 6. Intermediate chamber 7 formed by the housing 1 and the outer surface of the intermediate electrode 4, a charging chamber 8 formed by the inner surface of the intermediate electrode 4 and the charging electrode 5, the housing 1 is made of holes 9, which connects the cavity of the hopper chambers 2 with an intermediate chamber 7 and the hole 10 made in the housing 1 coaxially with the needle 6. In the intermediate electrode 4 made of the hole 11 and hole which mediate the electrode along the axis of the charging electrode. The geometry of the intermediate chamber 7 is selected so that the power line with the least tension in this chamber is located opposite the holes 12 and passes through the holes 11 in the direction of the needle 6.
The device operates as follows: the dust particles are in the container chamber 2 which is connected through the opening 9 with the volume of the intermediate chamber 7 formed by the housing 1 and the intermediate electrode 4. In the General case such hopper chambers 2 in the source of charged dust particles may be several, each with its varieties of dust particles. When voltage is applied to the hopper electrode 3, the dust particles through the openings 9 to flow into the intermediate chamber 7, where along the power lines of the electric field through the holes 11 into the region of the needle 6. If the dust particle, after charging has not fallen into the hole 13, or if not touched the needles 6, it moves into a zone of weak fields in the area of the holes 12, through which it falls back into the intermediate chamber 7.
Thus, to generate a stream of charged particles, is equal to the flow of the prototype will require approximately 100 times fewer dust particles, also hit the accelerator is not enough for what our average speed, than that of the prototype.
The source of charged dust particles, comprising a housing, hopper electrode, the charging electrode with a needle, hopper and the charging chamber, characterized in that between the charging electrode and the housing has an intermediate electrode formed between the housing and the outer surface of the intermediate electrode intermediate the camera, charging the camera is formed by a charging electrode and the inner surface of the intermediate electrode, the side surface of the intermediate electrode is made more holes that tells the charger and the intermediate chamber between itself and the hopper chamber formed by the casing and hopper electrode and in communication with the intermediate chamber through holes made in the body.

FIELD: physics, possible use in laboratory research, and also during development of new devices for medicine and engineering, where it is needed to eject electron or laser beams in impulse mode.
SUBSTANCE: the essence of method is in using the difference of spreading speeds of gas and electrons. Ejection channel is opened for the time, sufficient for flight of electrons, but insufficient for passage of gas molecules. This allows ejection of short electron beams of any power without loss of their energy with minimal flow of gas in direction of lesser pressure. Claimed device, which realizes the method, does not exhaust all of its capabilities. It is engineered for ejection of electrons from radioactive gas environment with pressure of 1Pa order into vacuum with pressure 10-5-10-6 Pa. Special feature of the method is that on its basis devices may be created for ejection of electron and laser beams without limitation of energy and distortion of their spectrum.
EFFECT: possible creation of devices, which, depending on conditions of operations in conjunction with various methods and means of vacuum and compressor engineering will ensure ejection of electron and laser beams of any energy into space with any pressure.
