Description
A modern helium refrigerator has replaced a 30-year old Philips cryogenerator on the 500 MeV cyclotron. Two ~11m long cryopanels are cooled down to 4.5K from the previous 17K, increasing pumping speed and improving reliability of the 90 m3 cyclotron tank vacuum system.
A 600 Watts helium refrigerator, supporting the ISAC Phase-I SC-linac, is now in routine operation. The Phase-II SC-linac will be cooled with an identical refrigerator, already commissioned and tested on the Phase-I section of the linac. This second refrigerator is being used for Phase-II linac developments, including new SC-cavity performance tests.
A 50 MeV, 500kW superconducting electron linac, with its 2K refrigeration system, is proposed as a primary development for the Laboratory.
Relevant design choices for the above systems, as well as results from recent operational and commissioning experience will be discussed.
