SUMMARY 

The APELC MG15-3C-2700PF is compact 15-stage generator that was designed to drive low-impedance resonant transmission lines for high-power RF. This generator is characterized by a 3 – 5 ns risetime and multi-GW peak power levels, due to its low-impedance design. The generator is capable of delivering 300 kV into a 23 Ohm matched load, or as much as 600 kV into an open circuit. The generator is designed to deliver 100 J per pulse and has been demonstrated to operate with a 100 Hz repetition rate with an integrated 10 kJ/s power supply.

  • Maximum open circuit voltage: 600 kV 
  • Peak voltage into matched load: 300 kV 
  • Maximum repetition rate: 100 Hz 
  • Energy per pulse: 100 J 
  • Pulse risetime: 3-5 ns
