Cyclic accelerators of elementary particles in a controlled final energy electrons

摘要

1. The betatron (1) to produce pulses of accelerated electrons, especially in the control of X-ray installation, having at least one coil (L1, L2) of the ground field, expansion coil (6) to emit the accelerated electrons on the target, and an electronic circuit ( 7) control the expansion coil (6) for supply to the expansion coil (6) of the expansion pulse, wherein the circuit (7) controls the expansion coil (6) is adapted to change the point in time of the expansion pulse with respect to the main field to thus adjust the final energy of the electrons, the electrons during the acceleration current to the expansion coil (6) does not podaetsya.2. Betatron (1) according to claim 1, characterized in that the time of the expansion momentum is variable relative to the main field from pulse to impulsu.3. Betatron (1) according to claim 1, characterized in that the circuit (7) controls the expansion coil (6) has a switchable semiconductor relay (9), in particular insulated-gate bipolar transistor (IGBT) .4. Betatron (1) according to claim 3, characterized in that the expansion coil (6) via a semiconductor switch (9) is connected to the independent source (10) into electrical energy tsep.5. Betatron (1) according to one of claims 1-4, wherein the presence of the coil control circuit (L1, L2) of the ground field adapted to enable and disable a current through the coil (L1, L2) of the ground field at any moment vremeni.6. Betatron (1) according to claim 5, characterized in that the coil control circuit (L1, L2) comprises a battery main field (C) energy, two power switches (TR1, TR2) and two diodes (D1, D2), at this- a first terminal (16) of the first silovog
