  Fermilab is developing a compact superconducting CSRF accelerator as a source
of a high-power, high-energy electron beam to produce an x-ray beam comparable
to $\geq$ 2 MCi of cobalt-60. As part of this development, we are presently
assembling a 20 kW, 1.6 MeV prototype that incorporates the four enabling
technologies described below. These technologies support a heat budget that is
within the capacity of commercially available cryocoolers and eliminate the
need for liquid cryogens. The use of superconducting technologies promises
efficiencies, wall-plug to beam, of 80% or greater. A summary of the design and
progress to date will be given. In addition, we will present a review of
developments within the medical device sterilization industry that are
motivating the development of this technology.
