Experience With Machine Protection Systems At PIP2IT
II Collaboration, A. Warner, M. Austin +10
The PIP-II Injector Test 1 PIP2IT facility accelerator was assembled in multiple stages in 2014 2021 to test concepts and components of the future PIPII linac that is being con…
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…
The Role of Magnetic Flux Expulsion to Reach Q0>3x10^10 in SRF Cryomodules
S. Posen, G. Wu, E. Harms +7
When a superconducting radiofrequency cavity is cooled through its critical temperature, ambient magnetic flux can become "frozen in" to the superconductor, resulting in degradatio…
Commissioning and Operation of FAST Electron Linac at Fermilab
A. Romanov, C. Baffes, D. R. Broemmelsiek +17
We report results of the beam commissioning and first operation of the 1.3 GHz superconducting RF electron linear accelerator at Fermilab Accelerator Science and Technology (FAST)…
Record High-Gradient SRF Beam Acceleration at Fermilab
Daniel Broemmelsiek, Brian Chase, Dean Edstrom +10
Many modern and future particle accelerators employ high gradient superconducting RF (SRF) to generate beams of high energy, high intensity and high brightness for research in high…
