The high power test model of biperiodic L-support disk-and- washer was fabricated. Among some trouble in the fabrication, the main one was a vacuum leak in a brazing process. The repair test of the leak showed a good result; four units were recovered out of five leak units (recover rate 80%). While an accelerating mode frequency was tuned at an operating frequency of 2857 MHz by squeezing method, a coupling mode frequency of 2847MHz and the 3.4% field flatness (peak to peak ratio) were achieved.
