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…
Compensating for Amplifier Non-Linearity in a SEL Controller
S. Raman, P. Varghese, L. Reyes +4
The Self-Excited Loop (SEL) architecture, used in some continuous-wave (CW) superconducting linacs, relies on a positive feedback mechanism that requires carefully defined operatin…
Drift Observations and Mitigation in LCLS-II RF
L. Doolittle, S. D. Murthy, A. Benwell +6
The LCLS-II RF system physically spans ~700m and has strict requirements -- on the order of 20 fs -- on the phase stability of the accelerating RF fields in its SRF linac. While ea…
LLRF System Analysis for the Fermilab PIP-II Superconducting LINAC
P. Varghese, S. Raman, M. Guran +4
PIP-II is a superconducting linac that is in the initial acceleration chain for the Fermilab accelerator complex. The RF system consists of a warm front-end with an RFQ and buncher…
SNS Front End Diagnostics
L. Doolittle, T. Goulding, D. Oshatz +2
The Front End of the Spallation Neutron Source (SNS) extends from the Ion Source (IS), through a 65 keV LEBT, a 402.5 MHz RFQ, a 2.5 MeV MEBT, ending at the entrance to the DTL. Th…
The Continuous Electron Beam Accelerator Facility at 12 GeV
P. A. Adderley, S. Ahmed, T. Allison +136
This review paper describes the energy-upgraded CEBAF accelerator. This superconducting linac has achieved 12 GeV beam energy by adding 11 new high-performance cryomodules containi…
