国产铌材超导腔的研制和实验

Research Progress of 1.5 GHz Chinese Niobium Superconducting Cavity

摘要: 通过对国产铌腔的研制和探索，掌握了超导腔的设计制造和实验研究的关键技术，进行铌材改进后获得了铌腔后处理的特定工艺．在２．５Ｋ温度时，国产铌腔的加速梯度超过１０ＭＶ／ｍ，品质因素１０９． The research progress of superconduting cavity made in Chinese Niobium,with the emphasis on the quality improvement of the Niobium andcorresponding superconducting cavity are introduced. The designing of the cavity geometry, analysing of the RF property of the Niobium as well as its mechanical quality are described. Special procedure of the cavity fabricating and its post processing are set. Experimentally, we got the gradient of 10MV/m and the quality factor of 10 9 at 2.5K.
