Description

TESLA-type 9-cell superconducting cavity (IHEP-04) was fabricated by IHEP (Institute of High Energy Physics, Chinese Academy of Sciences). The vertical test of the IHEP-04 cavity was carried out at KEK. Electropolishing (EP), annealing, pre-tuning and inspection of inner surfaces were carried out, prior to the vertical tests. The results of inspection of inner surface, which is largely related to the high-gradient performance in the IHEP-04 cavity, are described in this paper. (author)
