摘要: Abstract The parameters relevant to the use of ceramic insulator materials in resistive components for direct currents (dc) and transmission electromagnetic (em) waves are discussed. In components, radiation-induced conductivity radiation-enhanced electrothermal breakdown major concern. limits em power considered different plasma heating concepts. Special attention is given dielectric loss tangent. addition, mechanical thermophysical properties thermal crack formation reviewed. For particularly critical gyrotron window, technical analysis exemplified motivation cryogenic cooling presented.
