Abstract
Not Available For the objective of designing materials with the range of dielectric, thermo-mechanical and vacuum sustaining properties to match the current BeO-SiC lossy materials, several different dielectric matrix ¿ conductive dispersed phase combinations are proposed. A unique, Alternated Layers Dielectric aproach is also proposed, which would provide more direct thermal dissipation paths. In the proposed materials, the dielectric matrix phases are chosen to offer high thermal conductivity. The conductive, dispersed phase will be chosen to provide high dielectric losses over a wide range of microwave frequencies at lowest possible volume loadings. Both the matrix and the dispersed phase are chosen for their high temperature stability, and high potential for good vacuum sustaining characteristics. Data is shown, based on company's prior work, that suggests the approach is feasible. The Alternated Layer Dielectric approach potentially offers even higher thermal conductivities. The proposed program is based on Ceradyne, Inc. experience in lossy material development and manufacturing. A partnershp will be developed with current lossy ceramic users in the microwave industry, and with Oak Ridge National Laboratory. They have the ability to evaluate the newly developed lossy ceramics against BeO-SiC. A susbstitute family of materials would be developed that could be used instead of current lossy BeO-SiC lossy ceramic composites. Current BeO-SiC is being phased out due to health issues. Newly developed lossy material(s) would be used as microwave absorbers in TWTs, CCTWTs, Klystron amplifiers for military and commercial applications, and in the the construction of national accelerator facilities for basic research.
