Abstract

The compact electron linac RELUS-5 was developed for radiation investigation of material modification.

The experience of the standing wave electron accelerator building starting since first in the USSR standing wave electron linac RELUS-1 in 1978 [1] were used.

Electron energy range is from 3 to 5 MeV. Pulse length is from 3 to 6 μsec. Average power of accelerated beam is up to 1 kW.

The main task of submitted work is to build simple and cheap applied electron linac and to show how to do it.

Abstract

Compact solid state modulator is developed, assembled and tested. The modulator is designed for use in compact electron linac RELUS-5 to feed pulse mode magnetron and electron gun.

Main parameters of the modulator are: peak voltage 50 kV, peak current 100 A, pulse length 0÷6 μs, rise and fall time 0.5 μs, output power up to 10 kW.

The whole modulator is located inside the oil tank with overall dimensions 88×84×95 cm.

Special circuit allows to correct the droop of the pulse and to vary the pulse length in wide range.

Modular type design allows to use it as a base for the building of another modulators with higher peak voltage up to 150÷300 kV as well as with higher peak current up to 300 A.
