Updates on Sc Cavity Inspection

The temperature mapping (T-map), the eddy-current testing and other methods for inspection of the cavity interior surface is under development. T-map system can find heat sources that may be caused by defects on the superconducting accelerator cavity surfaces. The purpose of our studies on T-map is to realize a high spatial resolution and easy installation of the sensors. The production yield of such cavities would be improved by using these inspection systems. The preliminary tests of the T-map system and the eddy-current inspection are reported.
