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…
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…
Installation, commissioning, and testing of the HB650 CM at PIP2IT
M White, J Makara, S Ranpariya +10
The Proton Improvement Plan-II (PIP-II) is a major upgrade to the Fermilab accelerator complex, featuring a new 800-MeV Superconducting Radio-Frequency (SRF) linear accelerator (LI…
The Evaluation of Mechanical Properties of LB650 Cavities
J. Holzbauer, G. Wu, H. Park +13
The PIP-II project's LB650 cavities could potentially be vulnerable to mechanical deformation because of the geometric shape of the cavity due to reduced beta. The mechanical prope…
Transportation Fatigue Testing of the pHB650 Power Coupler Antenna for the PIP-II Project at Fermilab
J. Helsper, S. Chandrasekaran, J. Holzbauer +1
The PIP-II Project will see international shipment of cryomodules from Europe to the United States, and as such, the shocks which can occur during shipment pose a risk to the inter…
LCLS-II and HE Cryomodule Microphonics at CMTF in Fermilab*
C. Contreras-Martinez, E. Harms, C. Cravatta +7
Microphonics causes the cavity to detune. This study discusses the microphonics of sixteen 1.3 GHz cryomodules, 14 for LCLS-II and 2 for LCLS-II HE tested at CMTF. The peak detunin…
LCLS-II-HE verification cryomodule high gradient performance and quench behavior
S. Posen, A. Cravatta, M. Checchin +43
An 8-cavity, 1.3 GHz, LCLS-II-HE cryomodule was assembled and tested at Fermilab to verify performance before the start of production. Its cavities were processed with a novel nitr…
Commissioning And First Results From The Fermilab Cryomodule Test Stand
E. R. Harms, M. Awida, C. Baffes +34
A new test stand dedicated to Superconducting Radiofrequency (SRF) cryomodule testing, CMTS1, has been commissioned and is now in operation at Fermilab. The first device to be cool…
Improved RF Measurements of SRF Cavity Quality Factors
J. P. Holzbauer, C. Contreras, Y. Pischalnikov +2
SRF cavity quality factors can be accurately measured using RF-power based techniques only when the cavity is very close to critically coupled. This limitation is from systematic e…
Low Level RF Control for the PIP-II Accelerator
J. P. Edelen, B. E. Chase, E. Cullerton +9
The PIP-II accelerator is a proposed upgrade to the Fermilab accelerator complex that will replace the existing, 400 MeV room temperature LINAC with an 800 MeV superconducting LINA…
Systematic Uncertainties in RF-Based Measurement of Superconducting Cavity Quality Factors
J. P. Holzbauer, Yu. Pischalnikov, D. A. Sergatskov +2
Q0 determinations based on RF power measurements are subject to at least three potentially large systematic effects that have not been previously appreciated. Instrumental factors…
