Abstract
The LHC interaction region (LR) inner tripler cryostats are under development at Fermilab. The inner triplet consists of four 70 mm aperture superconducting quadrupole magnets manufactured at Fermilab and KEK. These magnets are cooled with pressurized static superfluid helium at 1.9 K which transports the heat to saturated 1.8 K He II via a He II heat exchanger. This paper discusses the requirements for the inner triplet cryostat, development of the cryogenic system, and He II heat exchanger arrangement. Cooldown and quench pressure issues with the external He II heat exchanger are also discussed.
