The cryogenic dielectric photonic cavity can reach the new field of the accelerating structure beyond both ot the superconducting cavity with high quality factor and the nomal conducting cavity with the high electric field.The photonic band gap can store the RF field in the cavity and the dielectric material has very low loss tangent at low temperature.The ceramic material for such purpose was studied including its manifacturing process and the evaluation of the electrical properties. And the accelerating structure was demostrated using the cryogenic and high power RF test stand.

低温介质光子谐振腔是一种超越高品质因数超导腔和高电场正常导电腔的新型加速结构，它的光子带隙可以将射频场存储在谐振腔中，介质材料在低温下具有很低的损耗角正切。本文研究了低温介质光子谐振腔的陶瓷材料，包括其制备工艺和性能评价的电气特性。并利用低温高功率射频实验台对加速结构进行了验证。
