Stangenes Industries is developing a novel klystron driver capable of peak modulator powers of 160MW and average powers of 320kW to drive a variety of high-powered electron-sources. The all-solid-state modulator consists of Marx generators driving parallel primaries of a pulse transformer achieving output voltages of over 500kV. Over 3000 hours of internal lifetime testing on the primary pulsing components have proven the ruggedness of the design.

Pulse flat-tops of 0.1%/µs are achievable with real-time klystron feedback, coupled with an optimization algorithm that automatically adjusts pulse parameters. Pulse RMS stabilities of less than 100ppm are necessary in many applications and require careful tuning of the charging elements.

  • Drawer system – the pulser unit or "stick" is meant to be directly replaced
  • MTTR for "stick" replacement < 10min.
  • Serviceability – drawer slide out breaks both water and electrical connections at pressure
  • Dielectric oil in transformer tank
  • Power - system runs off three-phase ~400VAC
  • Logic - several integrated MCUs and FPGAs for logic and triggering
  • Client - ethernet control, diagnostics, arc-handling and fault logging
