Abstract

The authors describe test results, Qs, gradients, and static and dynamic heat loads, for the CEBAF (Continuous Electron Beam Accelerator Facility) cryomodules along with the electrical and mechanical performance of the cryomodules manufactured to date. The vertical tests have resulted in Qs >10/sup 10/ at 5 MV/m as well as gradient approaching >16 MV/m. To this point, the authors have observed decreases in the Q/sub 0/ in the cryomodule test area followed by a good recovery during commissioning to nearly twice design value. The gradient has not appreciably decreased during any of the testing. The static heat loads have also met or exceeded the design specification. The current installed injector cryomodules exceeds the design of 25 MeV/c.<>
