Abstract

A software package has been created for examining the thermal behavior of cryogenic particle accelerator structures. It models the steady state heat flows in waveguides and beampipes while in operation, treating both diffuse and specular infrared reflection. The programs runs effectively on small computers, since only a few simple geometries are treated, and the output display options are limited. Overall accuracy for simple test cases is on the order of a few percent, but on short structures with very wide apertures the errors can be up to 10%. An analysis of radiative heat load in the B-factory cavity is presented, and thermal management strategies for the input waveguide are discussed
