Status of the Cold Mass of the Short Straight Section for the LHC

In the framework of the LHC (Large Hadron Collider) R&D program, CERN and CEA-Saclay have collaborated to develop and construct two quadrupole magnet prototypes which have been successfully cold-tested. This collaboration has been extended as part of French special contribution to the LHC project. The previous design has been adapted to meet the new LHC parameters and two new cold masses are being constructed. This paper describes the new cold masses, their assembly process and the foreseen organization for the industrial production of about 470 units. * CEA, DSM/DAPNIA/STCM, France. ** CERN, LHC Division, Geneva, Switzerland.
