A 20 MeV , 30 mA microtron is used as an injector to the booster. This
microtron is fully designed at RRCAT and has been fabricated locally. The
main feature of this microtron is that it is mounted in vertical
orientation to match the emittance of the electron beam from it with the
acceptance of the booster in the horizontal and vertical planes. Microwave
system consisting of a microwave source, a transmission line and a radio
frequency (RF) cavity has been also fabricated. Microwave source consists
of a 5 MW pulsed klystron and a solid state synthesizer. The components of
microwave transmission line are made in S-band WR784 waveguide section.
The transmission line is pressurized to 2.5 Kg/sq.cm. with dry nitrogen.
RF cavity is a cylindrical cavity resonant in TEM 010 mode. A cylindrical
pin of Lanthanum hexaboride is mounted on this cavity as an electron
emitter.
