In early 2023, Fermilab is conducting horizontal cryogenic testing of the first Q1/Q3 Cryo-Assembly for the high-luminosity LHC upgrade (HL-LHC). The Cryo-Assembly was installed on the upgraded Fermilab horizontal test stand previously used for testing the LHC inner triplet quadrupoles. The cryogenic process requirements of this test include controlled cool-down and warm-up with a 100 K maximum temperature differential between the two ends of the cold mass, operation of a 1.3 bar, 1.9 K bath of subcooled superfluid helium during power testing and magnetic measurements, and operation at pressure up to 18 bar with full helium recovery after a quench.
