First high power pulsed tests of a dressed 325 MHz superconducting   single spoke resonator at Fermilab
  In the recently commissioned superconducting RF cavity test facility at Fermilab (SCTF), a 325 MHz, {\beta}=0.22 superconducting single-spoke resonator (SSR1) has been tested for the first time with its input power coupler. Previously, this cavity had been tested CW with a low power, high Qext test coupler; first as a bare cavity in the Fermilab Vertical Test Stand and then fully dressed in the SCTF. For the tests described here, the design input coupler with Qext ~ 106 was used. Pulsed power was provided by a Toshiba E3740A 2.5 MW klystron.
