摘要

真空在粒子加速器中是必不可少的。低气体密度允许带电粒子束循环而没有过多的损失。实际上，光束损耗对仪器是有害的;它们增加了诱导放射性，粒子探测器中的背景噪声，以及低温设备的光束诱导热负荷。

Vacuum science and technology at CERN

Vacuum is essential in particle accelerators. Low gas density allows charged particles beams to circulate without excessive losses. Indeed, beam losses are detrimental for instrumentation; they increase induced radioactivity, background noise in particle detectors, and beam-induced heat loads to cryogenic equipment.

期刊介绍： Europhysics News is the magazine of the European physics community. It is owned by the European Physical Society and produced in cooperation with EDP Sciences. It is distributed to all our Individual Members and many institutional subscribers. Most European national societies receive EPN for further distribution. The total circulation is currently about 25000 copies per issue. It aims to provide physicists at all levels, ranging from post graduate students to senior managers working in both industry and the public sector, with a balanced overview of the scientific and organizational aspects of physics and related disciplines at a European level. Sections covered: ◦Activities ◦Features ◦News and views
