Marx Generator
MG24-20C-2700PF-PFN
Part Number: MG24-20C-2700PF-PFN
APELC’s MG24-20C-270PF-PFN Marx generator features a 24-stage, pulse-forming network (PFN) designed to source higher impedance microwave tubes. It includes a “by-pass” copper sulfate water resistor in the design for impedance matching, and to accommodate load impedances from 100 Ω to 200 Ω. This system is unique as its integrated PFN delivers a rectangular pulse to the load.The generator features a second ‘dummy-load’ port to facilitate a wide range of real-load impedances for both matching and waveform verification.
The system comes standard with several diagnostics, including a voltage monitor, a Rogowski monitor, and a B-dot monitor. The system also includes an internal safety dump and an optional side-mounted high voltage trigger unit.
