The application coated NEG as main pumpdown facility in the narrow extensive chambers of the particle accelarators
The vacuum system is an important and integral part of every modern scientific facility. The paper describes in detail the design and manufacturing of prototypes with coated non-evaporable getter (NEG) as main pumpdown for NSLS-II third generation synchrotron light source and for Coherent electron Cooling of eRHIC. TiZrV NEG sputtered film in the narrow extensive chambers is a vacuum technology for obtained ultra-high vacuum which is used in many particle accelerators worldwide. The experimental results of NEG film sticking probability for hydrogen are presented here.
