Particle beams require extremely low pressure in the pipes in which they travel to maximise beam lifetimes and minimise backgrounds in physics detectors. This challenge drives much of today’s vacuum R&D towards simulating, controlling and mitigating the direct and indirect effects of particle beams on material surfaces. CERN brings surface-physics specialists, thin-film coating experts and galvanic-treatment professionals, together with designers and others dedicated to the operation of large vacuum equipment. This makes it one of the world’s leading R&D centres for extreme vacuum technology, for projects at CERN and beyond.
