Industrial Building 1 (IB-1)

Cryogenic System:

A CTI-1500 Cold Box and an Air Liquide Helial LL Cold Box can provide a combined 640 L/hr of liquid helium.

The system includes 4 Kinney vacuum pumps to enable 2 K operation with a combined capacity of ~15 g/s

Currently Supports:

  • Test Stand 3 – magnet tests including LCLS-II SPQA, Mu2e HTS lead and splice.
  • Test Stand 4 – being modified to support HI-LUMI horizontal magnet testing.
  • LTCF – low temperature calibration of instrumentation including RTDs.
  • Vertical Test Stands (VTS) – 3 test stands for SRF cavity R&D and qualification tests for LCLS-II and other projects.
  • Vertical Magnet Test Facility (VMTF) – Magnet R&D and tests.

Meson Cryogenic Test Facility

Cryogenic System:
Three Tevatron style satellite refrigerators capable of ~1000W at 4.5K. A Kinney vacuum pump enables 2K operations to support single cavity loads of 10-20W.
Currently Supports:

  • Horizontal Test Stand (HTS) – Integrated cavity tests with fundamental power couplers and tuner, supporting LCLS-II 1.3 GHz and 3.9 GHz testing.
  • Spoke Test Cryostat (STC) – PIP-II 325 MHz Single Spoke Resonator integrated cavity tests, and being upgraded to test 650 MHz cavities for PIP-II.
  • Rapid Cycling Magnet Test Stand – International Advanced Accelerator R&D Fast-Cycling SC Magnets Tests.

Heavy Assembly Building (HAB)

Cryogenic System:
The helium cryogenic system consists of two Mycom screw compressors (60 g/s) supporting a 600 Watt at 4.5 K cryogenic plant previously used for the Tevatron Collider Detector Facility (CDF).
Currently Supports:

  • Testing of superconducting transport solenoids (14) for the future Mu2e experiment at Muon Campus. The test stand in the CDF pit consists of a cryostat with two removable top heads where solenoids are mounted and then inserted into the cryostat.
