CERN Technology to Create Massive Solar System in Switzerland

CERN Technology to Create Massive Solar System in Switzerland

Particle beams can circulate only in pipes from which the air has been removed, otherwise they would quickly be stopped. Vacuum technologies were therefore developed to meet the needs of the accelerators. For colliders, where accelerated particles are made to collide with each other, a high-grade vacuum is even more important. This is because they have beams of particles running for hours at a time, with a few particles actually colliding at any given crossing point. The world’s first proton-proton collider, the Intersecting Storage Rings (ISR), began operation at CERN in 1971, marking the start of ultra-high vacuum research at the Laboratory. At the end of the 1980s, CERN’s Large Electron–Positron collider (LEP) was setting new vacuum records, thanks to the use of 20 kilometres of getter strips, a material which attracts residual gas molecules like bugs to flypaper. But i...
