Closed Loop Testing of Microphonics Algorithms Using a Cavity Emulator
S. Raman, P. Varghese, B. Chase +4
An analog crystal filter based cavity emulator is modified with reverse biased varactor diodes to provide a tuning range of around 160 Hz. The piezo drive voltage of the resonance…

First high power pulsed tests of a dressed 325 MHz superconducting single spoke resonator at Fermilab
R. Madrak, J. Branlard, B. Chase +18
In the recently commissioned superconducting RF cavity test facility at Fermilab (SCTF), a 325 MHz, β=0.22 superconducting single-spoke resonator (SSR1) has been tested for the fir…
