“…However, it applies twice charging voltage of the storage capacitors to the switches and the DPF chambers, which greatly increases the insulation requirements of these components. Therefore, more generators use a direct capacitor discharge system [17][18][19][20], which is adopted in this paper. This technique allows one to get sub-microsecond or microsecond pulse current directly from the capacitors and the insulation requirements of the system depend on the charging voltage of the storage capacitor.…”

A pulse current generator applied in a type of high-yield intense pulsed neutron source, the Dense Plasma Focus (DPF), is designed and developed in this paper. There are three key components in this generator. Each group of capacitors and switches is integrative to meet the DPF's requirements of low circuit inductance. A coaxial multi-channel switch is developed to solve the problems of the switch inductance, the jitter and the electrode erosion. A kind of sectorial plate transmission line is adopted to transfer the high pulse current from the capacitors to the DPF. The following technical parameters of the generator were achieved on dummy load: output current amplitude of ∼560 kA when primary capacitors are charged with 22 kV.
