Non-Evaporable Getter (NEG) pumps are increasingly common in particle accelerator applications
because of their small size and their strong performance for hydrogen, the principal UHV gas.
However, these pumps present a challenge to vacuum system design because their complicated
geometry results in unreasonably complicated vacuum simulations. This project seeks to build 3D
models of NEG pumps and their environments in AutoDesk Inventor and simulate their performance
in MolFlow, creating a database to NEG performance under various installation geometries and
attempting to simplify the pump geometry without sacrificing simulation accuracy. Key results are
verified experimentally
