| Title | Preliminary Cryogenic Cold Test Results of the First 9-Cell LSF Shape Cavity | ||||
| Abstract | Following successful prototyping and testing of single- and 5-cell LSF shape cavities, the first 9-cell LSF shape cavity LSF9-1 was successfully constructed in-house with an improved process at JLab. The cavity was shipped to KEK for mechanical adjustment, treatment and surface processing. Cold testing was carried out at JLab VTA facility instrumented with a suite of Kyoto instruments. The favourable measured values of the bath pressure detuning sensitivity and Lorentz force detuning coefficient validate our in-cell stiffener design. Pass-band measurements indicate 4 out of 9 cells are capable of reaching a gradient > 45 MV/m, up to 51 MV/m in 2 cells. Cornell OST detectors identi-fied the current quench source. Multipacting-like bar-riers observed in end cells are investigated both ana-lytically and numerically. The cavity has now received a light EP of 40 micron surface removal at the joint ANL/FNAL facility and further cold testing at JLab is underway. Two new 9-cell LSF shape cavit | ||||
