Vacuum Acceptance Tests for Particle Accelerator Equipment

TL;DR

This paper discusses the importance of vacuum acceptance tests in particle accelerators, covering design, materials, cleaning, and outgassing, with a focus on CERN's testing procedures for baked and unbaked systems.

Contribution

It provides an overview of vacuum acceptance testing procedures and requirements specific to particle accelerator components, highlighting CERN's practices for both baked and unbaked systems.

Findings

Vacuum acceptance tests ensure reliable accelerator operation.

Material choices and cleaning processes impact vacuum quality.

CERN employs specific testing protocols for different system types.

Abstract

The effective and reliable operation of particle accelerator machines is strongly related to obtaining and keeping the required ultra-high vacuum level. This paper briefly presents some generic requirements to take in consideration for components that need to be installed in a particle accelerator like design constraints, materials choices, chemical cleaning process, outgassing rate, and their possible mitigation. Moreover, it will discuss vacuum acceptance tests put in place in the CERN accelerator complex for both, baked and unbaked system.
