Abstract
Microwave energy generated by the electron beam in the superconducting cavities of the Continuous Electron Beam Accelerator Facility (CEBAF) is absorbed by special loads fabricated with a novel lossy ceramic material (AIN-glassy carbon) developed especially for this application. Strict environmental constraints (ultra-high vacuum compatibility, operation at 2 K, brazeability, etc.) are imposed on the materials which can be used. Several other ceramics were sintered with AIN and various minority conductive powders to obtain the desired electrical properties according to the ‘artificial dielectric’ model. Dielectric permittivity data and results of low temperature measurements are reported.
