Abstract
The 4 tesla superconducting solenoid for the CMS detector planned for the LHC uses a high purity aluminium stabilised conductor and the indirect refrigeration method. The coil is cooled by a network of LHe tubes which are attached to the external coil wall and are supplied in a thermosiphon circulating mode.
The design of the cooling circuit must be adapted to the restricted space and must insure proper operation in all the working conditions. The thermosiphon loop has been simulated with a dedicated code for computation of the flow distribution through parallel channels and for circuit optimisation.
