Two standing-wave single-cell choke-mode damped structures with different choke dimensions which worked at 11.424 GHz were designed, manufactured and tuned by accelerator group in Tsinghua University. High power test was carried out to study choke-mode structure's properties in high gradient and related breakdown phenomenon. A single-cell structure without choke which almost has the same inner dimension as choke-mode structure was also tested as a comparison to study how the choke affects high-gradient properties. In this paper, we report on the latest status of the high power test, including various observations and the experimental results.
