A 3-kV, 3-Q, Fast Risetime Pulser
Abstract
A very fast risetime, low-impedance pulse generator has been constructed and tested. The pulser produces an approximate double exponential pulse at 3 kV into a 3-Q load. The 10 to 90 risetime is 600 ps and 1/e falltime is 30 ns. The pulse generator design is a dynamic peaking capacitor circuit. The pulser output consists of 16 parallel 50-Q cables. The output switch of the peaking capacitor circuit has 16 individual spark gaps operating synchronously. The main switch is triggered from an external source providing synchronization of the output pulse with a low-level initiation pulse. In the design, internal resonances are avoided by careful design of all components including the capacitors. A description of the design and operation of the system will be given.
