The Baba Atomic Research Institute has developed an electron gun that can be used for various extraction voltage and corresponding beam current extractions and can easily operate in triode mode with a grid bias and as an injector for electron beam applications along with irradiation of suitable products. A linear accelerator is a machine that aims radiation at cancer tumours with pinpoint accuracy, sparing nearby healthy tissue. It is used to deliver several types of external beam radiation therapy, including image-guided radiation therapy (IGRT)
Electron gun is the source of electrons for electron beam accelerators, which are used for industrial applications, medical applications, radiography and cargo-scanning applications. The 40 kV, 1.5 A thermionic electron gun can be used as injector for RF linac. It consists of a planar Lanthanum Hexaboride (LaB6) cathode indirectly heated by a tungsten filament which can be energized using a variac through an isolated filament transformer.
The major advantage of the LaB6 cathode based electron guns are its low thermionic work function, longer life, low contamination to exposure and it can work in higher vacuum levels. It is a major import substitute. Indigenously manufactured electron guns costing nearly one fifth of the imported machines could prove a cost effective solution to help the domestic industry improve product quality. The major advantage of the LaB6 cathode based electron guns are its low thermionic work function, longer life, low contamination to exposure and it can work in higher vacuum levels. It is a major import substitute, with cost effectiveness.
