Cold Tests of a sc 325 MHz CH-Cavity — •Marco Busch1, Florian Dziuba1, Holger Podlech1, Ulrich Ratzinger1, and Michael Amberg2,1 — 1IAP University of Frankfurt, Frankfurt am Main, Germany — 2Helmholtz-Institute Mainz (HIM), Mainz, Germany
At the Institute for Applied Physics (IAP), University of Frankfurt, a superconducting 325 MHz CH-Cavity has been designed, built and first tests at 4 K have been performed. The cavity is determined for beam tests with a 11.4 AMeV, 10 mA ion beam at the GSI UNILAC. It consists of 7 gaps and is a candidate to deliver a gradient of at least 5 MV/m yielding voltages of 2.5 MV and above. New properties of this compact structure comprise low electric peak fields, improved surface processing capabilities and power coupling. Furthermore dynamic bellow tuners are welded into the resonator controlling the frequency after cool-down and during operation. In this contribution first measurement results accomplished at 4 K at the cryo lab in Frankfurt will be presented.
