Superconducting Cavity Development for Free Electron Lasers.
Abstract
Significant progress was made toward the goal of developing cavity modules for a superconducting linear accelerator to drive a high average power Free Electron Laser. Through a combination of numerical modeling and experimental testing, a cavity geometry was developed that has the desired RF characteristics and that is ammenable to manufacture. Where possible, modifications to existing coupler designs were made to enhance their performance; weaknesses in coupler design were identified and addressed. A compact fully-integrated accelerator module, which could be replicated to form a high power FEL accelerator, was designed conceptually; feature include cryostat, cavities, couplers and tuning mechanism. Facilities for fabricating full size superconducting cavities meeting all technical requirements were initiated. Gradient enhancement tests on superconducting subscale models of the cavity were performed successfully.
