Recirculating gas stripper system for 15 UD Pelletron

A new recirculating turbo molecular pump-based gas stripper system has been designed and installed in the high-voltage terminal of the 15 UD pelletron. The system has been installed as a part of the Accelerator Mass Spectrometry facility development program and is being used for regular accelerator operation. The vacuum inside the accelerator during gas strip has improved considerably. Beam transmission through the accelerating column is increased. The system is performing satisfactorily. The design and performance of the gas recirculating system is presented.
