In RFNC-VNIIEF there is being created a four-module electrophysical facility “Gamma-4” (2 MV, 3 MA, 320 kJ, 60 ns), meant for studies in the area of radiation physics. A typical module, involving systems of high-volt pulse formation and energy transmission to the load unit, have been developed and experimentally tested for the facility. On the matched load the module generates an electric pulse with...
RFNC-VNIIEF is developing a four module electrophysical facility “Gamma-4” (2 MV, 3 MA, 60 ns), meant for generation of powerful bremsstrahlung radiation pulses (BR). One of the basic modes of the facility operation is a mode of each module operation with its autonomous vacuum diode.
Presented is a sectioned vacuum insulator of a standard module of “Gamma-4” electrophysical facility developed at RFNC-VNIIEF. The given sectioned vacuum insulator is a component part of the module's pulse transmission system, which supplies transportation of a high-volt electric pulse from the forming system output up to the load unit. A specific feature of the insulator structure is employment of...

A design of a synchronization system for the four-module “Gamma-4” electrophysical facility has been developed. The synchronization system is meant for triggering (with precision not worse than plus or minus 3 ns) of high-volt gas-filled trigatron type switches of facility modules' pulse forming systems (144 items, operating voltage 1 MV), modules' pre-pulse switches (24 items, operating voltage 3...
To conduct radiation studies and tests, a four-module electrophysical facility «Gamma-4» is being created in RFNC-VNIIEF1. The facility is to be used in two operation modes: in a mode of generation of bremsstrahlung radiation pulses with limiting quantum energy up to 2 MeV when using one or several high-current electron vacuum diodes and in a mode of powerful pulse generation of soft X-Ray radiation...
