Device EMIR - M generator of impulse electron beams, bremsstrahlung and electromagnetic fields

Impulse high voltage electron beam accelerator EMIR - M consists of a capacitive energy storage in the form of Marx generator with 24 parallel modules, an intermediate inductive storage, an electrically exploding wire current interrupter (EEWCI), and diode type accelerator tube. Marx generator open - circuit voltage is up to 1.52 MV. The generator has 0.58 MJ store energy when the capacitance is 505 nF Its proper inductance is 1450 nH. The characteristic impedance of the generator - interrupter circuit is 2.5 Ohm. The EEWCI provides obtaining an accelerating voltage up to 5 MV and diode current 50 … 100 kA with the current pulse width 50 … 200 ns. The device is used in the following modes of operation: (1) Extraction of electron beam out of diode with an energy density up to 300 J/cm² and pulse width 100 ns; (2) Bremsstrahlung generation with an effective gamma foton energy approximately 1 Me V Maximum dose rate near anode is 2 * 10¹² Rad/s; (3) Generation of electromagnetic field in the radiation zone by another generator. An electric field up to 400 kV/m and magnetic field up to 1.2 kA/m are attainable with pulse rise time 40 ns and full width at half - maximum of 1 µs. The electromagnetic field may be generated simultaneously with the radiation impulse, time shifted relative to one or separately.
