Our microtron is a Kapitza type in which the electron emitter made of LaB6 is set in a cavity wall under magnetic field of the microtron. The extracted beam peak current recorded 400mA at 1MeV and 300 mA at 4 MeV that is extremely high. The reason for this high current is due to the applied 1 MeV high RF voltage. Acceleration efficciency is high because the only energy selected beam is accelerated. The size is 20cm for 1 MeV and 35 cm for 4 MeV machine. Currently we obtaine 20 mm*mrad emittance with 3mm diameter cross section emittor. Reduced emittor size will provide a few mm*mrad emittance.
