Design of the CEBAF Energy Upgrade Cryomodule Cold Mass

PDF Version Also Available for Download.

Description

The Jefferson Laboratory Energy Upgrade to 12 GeV will be accomplished by designing a new cryomodule with an increase in effective length of 40 percent while maintaining the same nominal cryomodule slot length within the linac. This is being achieved by changing from an eight five-cell cavity structure to an eight seven-cell cavity structure and removing all bellows between the cavities along the beamline. This approach has presented significant challenges with respect to the design as it pertains to the cooldown, support, alignment and tuning criteria. The solutions to these design challenges will be presented with an emphasis on cavity ... continued below

This approach has presented significant challenges with respect to the design as it pertains to the cooldown, support, alignment and tuning criteria. The solutions to these design challenges will be presented with an emphasis on cavity operational criteria along with the integrated support components to include higher order mode couplers,fundamental power couplers and tuning accommodations for a one-hertz resolution.
