Status update on the second-generation ILC Marx modulator prototype

Abstract

Abstract-This paper is a status update of the SLAC P2 Marx. This Marx-topology klystron modulator is a second-generation modulator which builds upon experience gained from the SLAC P1 Marx. There are several fundamental differences between these modulators including the correction scheme, bus voltages, and the control system architecture. These differences, along with preliminary experimental results and the schedule for further development, are detailed in this paper.

Accelerator Engineering and Technology: Accelerator Technology

“…Ignitrons are being phasedout from existing applications due to their mercury content, and resulting safety and environmental risk. Topologies such as the inductive adder [181][182][183] and Marx generator [184,185], utilizing fast and high-voltage semiconductor switches such as MOSFETs, are being actively pursued by CERN as possible alternatives to both thyratron and PFL technologies. The inductive adder and Marx generator use the series and parallel connection of power semiconductor switches to achieve high pulse power designs.…”

Final design of the SLAC P2 Marx klystron modulator

“…The design process involved with selecting the parameters utilized in the P2 Marx are detailed elsewhere [7,4]. The cell parameters are summarized in Table 2.…”
