The 3 MeV Accelerator Project involves designing, fabrication, installation and commissioning of a 3 MeV, 30 kW Industrial Electron Beam Accelerator with a terminal voltage of 3 MV and is housed inside the Electron Beam Centre building at Kharghar, Navi Mumbai. The Accelerator has capability of delivering electron beam of 3 MeV energy for radiation processing applications. For ecological and economical reason, the SF6 gas is reincorporated into closed cycle because gas should not be released into the atmosphere. The aim of the SF6 gas handling system is to introduce the gas at high pressure to the accelerator tank after evacuation and to bring back into the storage tanks with minimum loss. The gas handling system also provides purification of gas, prevention from mixing with air or any other substances, which may contaminate and thus bring down the high voltage insulation characteristics of the gas. This paper discusses about mechanical design, fabrication, testing and safety of different components of SF6 gas handling system such as gas piping, non lubricating compressor, dryer, vacuum pump, dust & oil filters, storage tanks etc.
