Adsorption and desorption properties of TiZrV getter film at different temperatures in the presence of synchrotron radiation

The coating of vacuum chambers with TiZrV non-evaporable getter (NEG) developed at CERN is an attractive pumping technology for vacuum systems. Once activated the NEG coating is a material since apart from providing distributed pumping, it may inhibit the gas desorption from the vast reservoir of th...

description The coating of vacuum chambers with TiZrV non-evaporable getter (NEG) developed at CERN is an attractive pumping technology for vacuum systems. Once activated the NEG coating is a material since apart from providing distributed pumping, it may inhibit the gas desorption from the vast reservoir of the industrially prepared substrate material. The present work includes an advanced study of NEG properties under Synchrotron Radiation (SR) at temperatures in the range from 300K to 90K. The work was performed at BINP using SR from the VEPP-3 storage ring. The main result is that dynamic pressure and desorption of H2 inside NEG coated chamber at 90K are significantly less than those at room temperature.
