COLDEX (COLD bore EXperiment), installed in the Super Proton Synchrotron (SPS) at CERN, is a test vacuum sector used in 2001-2004 to validate the Large Hadron Collider (LHC) cryogenic vacuum system with LHC type proton beams. In the framework of the R&D for the High Luminosity upgrade of the LHC (HL-LHC), COLDEX has been re-commissioned in 2014. The objective is the validation of the performance of amorphous carbon (a-C) coating at cryogenic temperature with LHC type beams. The existing COLDEX Cu beam screen has been therefore dismounted and carbon coated, while a complete overhaul of the vacuum, cryogenic and control systems has been carried out.

Abstract
COLDEX (COLD bore EXperiment), installed in the Super Proton Synchrotron (SPS) at CERN, is a test vacuum sector used in 2001-2004 to validate the Large Hadron Collider (LHC) cryogenic vacuum system with LHC type proton beams. In the framework of the R&D for the High Luminosity upgrade of the LHC (HL-LHC), COLDEX has been re-commissioned in 2014. The objective is the validation of the performance of amorphous carbon (a-C) coating at cryogenic temperature with LHC type beams. The existing COLDEX Cu beam screen has been therefore dismounted and carbon coated, while a complete overhaul of the vacuum, cryogenic and control systems has been carried out. This contribution describes the phases of recommissioning, reviews the current experimental set-up and gives an overview of the possible measurements with COLDEX, in view of its HL-LHC experimental program.| File | Dimensione | Formato | |
