TJS TECHNOLOGIES LLC — Department of Energy SBIR Phase II: 29c

Description

The Office of Nuclear Physics long range plans include allocation of resources to develop technology for a polarized electron-ion collider. Detrimental energy develops within the high current superconducting radio frequency cavities and interferes with the performance of the collider. Technology developed here will extend to many high current colliders and accelerators. To preserve the beam and its characteristics the cavities require energy absorption. Details of a broadband absorber design allow for conforming to either a waveguide or beamline absorber. RF, Thermal and Structural Analysis were completed to show feasibility. The primary absorbing component and holder were joined to demonstrate the manufacturing process and provide excellent thermal contact. A preliminary design was completed to develop costs. In Phase II we will develop a detail design of prototype absorbers including support structure and instrumentation features. Enhancements to the design and improving the power handling capability will be explored. Both a beamline and a waveguide prototype will be built and will be provided to a DOE Lab for testing after Phase II. Commercial Applications and Other Benefits: Future accelerators for treating potable water, waste water, medical waste cleansing, treating asphalt to improve wear, and other energy and environment needs can be addressed with high current accelerators, these accelerators will require absorbers.
