The main components of the cryogenic system for the superconducting LI
NAC being constructed al TIFR, Mumbai, are the closed cycle helium ref
rigeration system and the modular cryostat for housing the acceleratin
g cavities. One cryostat has been designed, fabricated and tested usin
g the dosed, cycle helium refrigeration system. Details of the cryogen
ic system are discussed.
