The coating of vacuum chambers with TiZrV non-evaporable getter (NEG), developed at CERN, is an attractive pumping technology for vacuum systems. The NEG coating, once activated, is an attractive material since apart from providing a distributed pumping, it may inhibit the gas desorption from the vast reservoir of the industrially prepared substrate material. The present work includes the advanced study of NEG properties under Synchrotron Radiation (SR) at temperatures in the range from 300K to 90K. The work was performed at BINP with using of SR from 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 ones at room temperature. |
