EUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH CERN-AT DIVISION CERN/ AT-CR/92-1 Process Control Methods for Operation of Superconducting Cavities at the LEP Accelerator at CERN


The aim of this work is to analyse the cryogenic process for cooling superconducting radio-frequency accelerator prototype cavities in the Large Electron-Positron collider (LEP) at CERN. A liquefaction cryoplant is analysed, including the production of liquid helium at 4.5 K, the systems for distribution and control of liquid helium, and the radio-frequency… (More)
