Heat load measurements for the PIP-II pHB650 cryomodule
D. Porwisiak, M. J. White, V. Roger +11
Phase-3 testing of the pHB650 cryomodule at the PIP-II Injector Test Facility was conducted to evaluate the effectiveness of heat load mitigations performed after earlier phases of…
Integration and commissioning plan of Full Flow Purifier at Muon Campus
J. Subedi, T. Tope, B. Hansen +5
The Full Flow Purifier for Fermilab's Muon Campus uses a charcoal bed surrounded by a liquid nitrogen jacket to purify up to 240 g/s of helium gas. Fabrication by Ability Engineeri…
Cold Test Results of Pre-Production PIP-II SSR2 Cavities with High-Power Couplers in the Fermilab Spoke Test Cryostat
A. Sukhanov, C. Contreras-Martinez, C. Grimm +13
As part of the PIP-II project at Fermilab, a pre-production cryomodule featuring 325 MHz Single Spoke Resonator type 2 (SSR2) superconducting RF cavities is under construction. The…
Performance of PIP-II High-beta 650 Cryomodule After Transatlantic Shipping
J. Ozelis, M. Barba, J. Bernardini +27
After shipment to the Daresbury Lab and return to Fermilab, the prototype HB650 cryomodule underwent another phase of 2K RF testing to ascertain any performance issues that may hav…
Design of Muon Campus full flow purifier for varying operational conditions and horizontal shipping
J. Subedi, T. Tope, B. Hansen +4
Constant ingress of impurities in Muon Campus g-2 experiment at Fermilab has resulted in reduction of efficiency of cryogenic expanders and occasional undesired downtime to flush t…
Nitrogen Precooling Heat Exchanger replacement and control system upgrade in Superfluid Cryoplant at CMTF
J. Subedi, B. Hansen, M. White +4
Liquid Nitrogen precooling is used in most Cryoplants to achieve cooldown to 80 K temperature range. In one such system at Fermilab's CMTF Superfluid Cryoplant, where the Helium su…
