Abstract
- Abstract: In order to guide the high energy proton beams inside its two 27km long vacuum rings, the Large Hadron Collider (LHC) at CERN, Geneva, makes use of superconducting technology to create the required magnetic fields. More than 4000 beam screens, cooled at 7–20K, are inserted inside the 1.9K beam vacuum tubes to intercept beam-induced heat loads and to provide dynamic vacuum stability. As extremely high helium leak tightness is required, all beam screens have been leak tested under cold conditions in a dedicated test stand prior to their installation. After describing the beam screen design and its functions, this report focuses on the cold leak test sequence and discusses the results. [Copyright &y& Elsevier]
