[en] NEG (Non Evaporable Getter) pumping technology is becoming very popular in vacuum applications as it provides very large pumping speed in a compact package. In particular, the deposition of getter thin film on the internal surface of a particle accelerator chamber allows to reduce the outgassing rate while providing large pumping speed inside beam pipe. This is advantageous in narrow gap or small diameter beam pipes which could not be otherwise effectively pumped by lumped pumps, due to conductance limitations. The main features of NEG coatings and their application to complex and narrow gap chambers, like for example insertion devices of synchrotron light sources, will be presented and discussed. Critical technological issues, process limitations and future perspectives are illustrated from the point of view of an industrial provider. New advances in getter materials and pumping technologies will be also illustrated with a special focus on a novel generation of getter pumps which can be used at pressure as high as 10"-"7 mbar. This allows to extend operational range of application of NEG pump from UHV-XHV regime to High Vacuum applications. (author)
