Tests Of The Extended Range SRF Cavity Tuners For The LCLS-II-HE Project*
C. Contreras-Martinez, T. Arkan, A. Cravatta +7
The LCLS-II HE superconducting linac can produce multi-energy beams by supporting multiple undulator lines simultaneously. This could be achieved by using the cavity SRF tuner in t…
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…
Validation of the 650 MHZ SRF tuner on the low and high beta cavities for PIP-II at 2 K*
C. Contreras-Martinez, S. Chandrasekaran, S. Cheban +7
The PIP-II linac will include thirty-six beta=0.61 and twenty-four beta=0.92 650 MHz 5 cell elliptical SRF cavities. Each cavity will be equipped with a tuning system consisting of…
Simulated Lorentz Force Detuning Compensation With A Double Lever Tuner On A Dressed ILC/1.3 GHZ Cavity At Room Temperature
C. Contreras-Martinez, Y. Pischalnikov, J. C. Yun
Pulsed SRF linacs with high accelerating gradients experience large frequency shifts caused by Lorentz force detuning (LFD). A piezoelectric actuator with a resonance control algor…
Accelerated Lifetime Test of The SRF Dressed Cavity/Tuner System for LCLS II HE Project
Y. Pischalnikov, T. Arkan, C. Contreras-Martinez +5
The off-frequency detune method is being considered for application in the LCLS-II-HE superconducting linac to produce multi-energy electron beams for supporting multiple undulator…
