The CERN East Area Renovation

摘要

The East Area at CERN's Proton Synchrotron delivers since over 56 years primary proton and ion beams as well as mixed secondary beams of hadrons, electrons and muons in a range of 0.5 GeV/c to 12 GeV/c. The CERN Management approved in 2016 a full renovation of this intensively used facility. It includes a new flexible beam design to meet todays physics requirements, which concern R&D detector tests, samples analyses undd high flux irradiation or physics studies (like the CLOUD experiment). This will result in the ability to run with highly pure electron, hadron or muon beams. The upgrade of the East Area also improves energy consumption with a pulsed powering scheme with new laminated magnets and energy recovering power converters that will reduce both power and cooling requirements. The renovation has already started. The first beam in the new East Area is expected to be delivered in 2021.
