Technology Summary
The APELC MG40-3C-2700PF is a mega-volt class Marx generator that was originally designed to drive an integrated flash x-ray diode. With a maximum 40 kV charge voltage, this generator has an open circuit voltage of 1.6 MV. And with a source impedance of approximately 70 Ohm, an 850 kV pulse has been measured with a 50 Ohm coaxial cable load. This generator has a maximum pulse energy of 260 J, and is capable of delivering more than 10 GW of peak power.

Measured output pulse waveform into a 50-Ohm cable load at full Marx charge voltage.
