Abstract :
The formation of the runaway electron beam in the coaxial gas-filled diodes was studied by computer simulation with PIC codes KARAT and OOPIC Pro. The runaway electron current dependence of pressure for the different diode schemes was obtained. It has been shown that the runaway electron is generated mostly in cathode region. The emission process affect to the current and duration of the runaway electron pulse was studied.
