Abstract
The Radio Frequency (RF) Cavities for the Continuous Electron Beam Accelerator Facility’s (CEBAF) superconducting linear accelerator have been design to operate at 2.0 K. A significant portion of the heat load to the 2 K system is supplied by the waveguides for the RF cavities. This heat load consists of three major components: a radiative component through the waveguide’s throat, a conductive component along the wall of the waveguide, and a heat generation component caused by the interaction of the RF wave with the waveguide’s wall.
A numerical model has been developed to evaluate the waveguide heat load. Utilizing this model, the influence of the conductive, radiative and generation com-ponents of the heat load have been evaluated and minimized.
The Southeastern Universities Research Association (SURA) operates the Continuous Electron Beam Accelerator Facility for the United States Department of Energy under contract DE-AC05-84ER40150.
