XT-map System for Locating SC Cavity Quench Position

XT-map system under development in collaboration between Kyoto University and KEK is a combined system of T-map and X-map. High resolution T-map at quench detection will give more information for improving yield in production of high performance SC Cavities. The high-density sensor distribution of the XTmap gives the high resolution. Because the huge amount of sensor lines are multiplexed at a hi-speed scanning rate in the vicinity of the sensors, the small number of signal lines makes the installation process easy and reduces the system complexity. The quench survey test with this XTmap system has been performed in the vertical test at KEK.
