A stand of laboratory practicum on corpuscular and electromagnetic irradiation has created. The stand makes it possible to generate electron beams, X-rays, discharges of various types and laser radiation within the framework of one installation. The stand is placed at the Electrophysics Chair of USTU-UPI.
Multifunctional non-thermal plasma source on the base of frequency high-voltage generator with a semiconductor opening switch
Waveforms of accelerating voltage (1), current of non-self-sustained discharge initiated by electron beam (2), and electron beam current after passage of an output foil (3).
Voltage of discharge supply is 10 kV. Horizontal scale: 20 ns/division. Vertical scales: 25 kV/division (1), 100 A/division (2), 5 A/division (3)
A compact pulsed electron accelerator ELIS has created in collaboration with Pulsed Power Laboratory. Peculiarity of the accelerator is a division of high-voltage pulse generator and vacuum diode. The generator and the diode are connected by high-voltage cable. Such a construction allows to direct an electron beam to any part of irradiated object, and also to decrease a dimension of radiation protection significantly. Main parameters of the ELIS accelerator are: electron energy – 100 keV; beam current pulse amplitude – 50 A; half-high beam current pulse duration – 1 ns; beam current density after output foil ∼102 A/cm2; beam cross section diameter – 0.7 cm; maximum pulse repetition rate – 100 Hz. Dimensions of the high-voltage block – 530×400×220 mm. Dimensions of the electron gun (irradiator) – Ø50×100 mm. Length of the high-voltage cable – 1 m.
