摘要：

This paper reports on the design, fabrication, RF measurement, and high-power test of a prototype accelerator-such as 11.424 GHz with 12 cells-and a traveling wave of two halves. It was found that the unloaded gradient reached 103 MV/m during the high-power test and the measured breakdown rate, after 3.17 x 10(7) pulses, was 1.62 x 10(-4)/pulse/m at 94 MV/m and a 90 ns pulse length. We thus concluded that the high-gradient two-half linear accelerator is cost-effective, especially in high-frequency RF linear acceleration. Finally, we suggest that silverbased alloy brazing can further reduce costs.
