IGUR-3 — Powerful bremsstrahlung radiation pulse generator

Electron accelerator IGUR-3 belongs to class of direct drive accelerators and is used for radiation investigations. Simplified electric scheme of accelerator is presented in Fig. 1. Inductive energy store with, wire-explosion switch is used to formation of high-voltage pulse. Accelerator IGUR-3 is located in room with sises 24 × 18×12 cub. meters. Accelerator construction is drawn in Fig.2. Total high is 8-5 meters, largest diameter is 7.5 meters. IGUR-3 is the first IGUR-type accelerator in which transformer oil is used as insulator of high-voltage units. The most important units of installation are: - Marx generator; - pulse forming system (PI´S); - electron beam diode; Marx generator of IGUR-3 consists of two parallel working units with the same charge scheme. Units are located symmetrically each other and FPS tank in loop-forming container. The using of two parallel units, the way of its arrangement and location in container allow to create generators with relatively small inductance.
