SRF cavities are starting to be recognized as not only research devices but as devices that might be able to step in as an improved and cost-efficient alternative to the existing room temperature high average power industrial accelerators. The largest issue in fostering this change in applicable areas is the cost of the infrastructure and cytotechnology required when maintaining cryo-liquids. The bulky cryoplants are presently synonymous with the SRF accelerator technology, thus limiting people’s perception and therefore undermining commercial potential of the SRF accelerators. Although, to reverse such perception, few smaller cryomodules have already been developed, as a rule these projects have not invested in the level of analysis required for field deployment, instead focusing on building these delicate devices at their final test locations. RadiaBeam Technologies proposes to design and build a cryomodule that operates without any cryo-liquids utilizing cryocoolers and conductive cooling. Removing the large expense of cryo- fluids also reduces transportation concerns since the cryomodule becomes just a vacuum device, and not a potentially high-pressure vessel. Further, RadiaBeam will implement the necessary analysis to make such cryomodules consistent with the deployment on a mobile platform. In Phase I, the cryomodule design and analysis will be fostered to an advanced concept to be presented for phase II fabrication. This will include the necessary thermal, structural, and magnetic shielding analysis. We will further perform ancillary component research and selection of the cryocooler, compressors and a closed loop chiller needed for final deployment.This device would have immediate benefit to existing SRF facilities now as an independent module utilized for capability expansion. This product would also address the desire of fostering compact SRF technology into industry and small laboratories. Some examples of typical areas of interest that would apply are: cargo inspection and security, food irradiation, bulk material treatment, and environmental issues such as waste water treatment.
