High power Industrial Electron Accelerator:
Development of 2.5 MeV/ 100 kW air-core transformer type Industrial Accelerator is in progress at RRCAT in collaboration with Budkar Institute of Nuclear physics, Russia. Energy of the accelerator can be varied from 1 to 2.5 MeV with electron beam current up to 50 mA and maximum beam power up to 100 kW. It is to be used for long term, round the clock continuous operation under industrial condition. Following table shows the design specification of the system.

Experiments have been performed at BINP, Novosibirsk Russia for the measurement of beam energy using calibrated energy probe, measurement of beam current, measurement of linear density distribution of the beam current under the extraction device window and long time tests for its stable operation and are reported in InPAC 2006 [3]. Following photograph shows assembly of primary windings at RRCAT ready for test with inverter.
