CONCEPT OF MOBILE SOURCE OF NARROW GAMMA RADIATION

A concept of the mobile source of narrow gamma-radiation on the basis of an electron accelerator with electron energy until 300-500 MeV and a convertor is proposed. Mobility of the source is conditioned by reduction of mass and longitudinal dimensions of the accelerator through special choice of the acceleration concept: operation by stored energy, increase of the supply power by decrease of the pulse duration, optimization of the accelerating structure and modification of the microwave power system.
