HSC加速器的初步大功率加速实验

Initial High Power Test of HSC Type Linac

混合单腔(HSC)型直线加速器是将一段4杆型射频四极(RFQ)加速结构和一段交叉指(IH)型漂移管(DT)加速结构混合到一个IH型腔里,利用IH型腔体具有的低功耗加速梯度高的优点,使得整个IH型混合腔的加速功率效率较其他加速结构腔体的更高。本文进行了低功率测试和初步大功率C6+加速实验。结果显示低功率测试结果与计算结果吻合较好,初步的大功率测试结果表明HSC加速器能满足下一步的高功率实验。

A novel hybrid single cavity （HSC） linac, formed by combining a radio fre- quency quadrupole （RFQ） structure and a drift tube （DT） structure into one interdigi- tal-H （IH） cavity, was fabricated, assembled and tested as a proof of principle type injector for cancer therapy synchrotron. The HSC linac is a power-efficient cavity. The low power test and the high power acceleration test were carried out. The low power test results are in good agreement with the calculation results. The high power test results show that the HSC linac can meet the high power test in the next step.
