Marx Generator
MG83-1C-150NF
Part Number: MG83-1C-150NF
APELC’s MG83-1C-150NF Marx Generator was built for the world’s largest vertical electromagnetic pulse (EMP) simulator located at the Patuxent River Naval Air Station (NAVAIR).
This generator uniquely brings a wide-charging voltage range of 8 kV – 50 kV, which results in an open-circuit voltage of 660 kV – 4 MV. With a matched 70 Ω load resistance, a maximum peak power of 230 GW is delivered with a pulse energy of 14.45 kJ. A rise-time of approximately 180 ns has been measured into a matched load.
This generator also features unique spark gap switch blocks, in sets of 6 switches, which aid in the wide operating range made possible by the line-of-sight UV optical coupling within the individual blocks. The Marx circuit is insulated with transformer oil, and the spark gaps are insulated with pressurized dry breathable air.
With APELC’s custom transfer and peaking circuits, rise-times as fast as 1.2 ns have been measured.
