title = "Alignment of CEBAF cryomodules",
abstract = "CEBAF, the Continuous Electron Beam Accelerator Facility, when completed, will house a 4 GeV recirculating accelerator. Each of the accelerator's two linacs contains 160 superconducting radio frequency (SRF) 1497 MHz niobium cavities [1] in 20 cryomodules. Alignment of the cavities within the cryomodule with respect to beam axis is critical to achieving the optimum accelerator performance. This paper discusses the rationale for the current specification on cavity mechanical alignment: 2 mrad (rms) applied to the 0.5 m active length cavities. We describe the tooling that was developed to achieved the tolerance at the time of cavity pair assembly, to preserve and integrate alignment during cryomodule assembly, and to translate the alignment to appropriate installation in the beam line.",
