100-kJ microsecond REB transport in a one-meter solenoid

Experiments on high-power electron beam transport through a gas along the strong magnetic field. A 1.1 MeV have been conducted 70 kA, 5 μs beam can be produced in a planar vacuum diode of U-1 accelerator (the initial total energy of the beam is 140 kJ and current density up to 0.2 kA/cm2). The beam injected through a thin anode foil is focused in a converging magnetic field and after 20-fold compression (magnetic field in the mirror is 8.8 T) propogates in a 1-meter solenoid with Bs=4 T. The beam transport has been investigated in the 10-8-1 Torr pressure regime. The transport of the macroscopically uniform REB with 110 kJ content and current density up to 2 kA/cm2 has been carried out
