Design and Low Power Test of Pulse Forming Network for Klystron Modulator at Chiang Mai University

A new pulse forming network (PFN) for klystron modulator has been designed and tested at Plasma and Beam Physics Research Facility (PBP), Chiang Mai University. The PFN consists of six capacitor and inductor sections. The output waveform of the PFN has pulse width of 3.2 μs and a flat-top of 2.0 μs with ripple less than ± 2.0%. In this paper discusses the design, simulation and low power test results of the PFN.
