We present the design, construction, and characterization of a line-type pulse high-voltage modulator system capable of generating 140-kV, 6 μs pulses width at 150 pulses per second into a Klystron as load. The modulator is used to energize a variety of highpower microwave devices requiring voltage stability and reproducibility. Voltage ripple is less than 0.4% during the flat top, with a shot-to-shot voltage variation of less than 0.2 %. The primary circuit consists of six-stage tuneable pulse-forming networks (PFN's). The PFN is charged by a highly stable charging power supply. The total energy stored is released through a CX-1559 E2V make thyratron into a 1: 11 pulse transformer, which generates 140 kV, 6 μs pulses. The flat-top voltage generated by the modulator is highly desirable for driving RF sources requiring high quality electron beams. Linac is one of the important fields of study in modern technology due its wide applications for medical and industrial purposes in addition to physics research. (author)
