加速器可用于强子疗法，一种用强子束照射患者的癌症治疗方法。为此，意大利TERA基金会提出了“回旋加速器”，由一个高频直线加速器组成，它可以加速由回旋加速器加速的强子。主要的研究目标是通过实现更高的加速梯度来减少直线加速器的长度，而不影响加速器的可靠性。为了测量高梯度极限，TERA设计、制造了一个3GHz单腔规管腔，并进行了大功率测试。本文介绍并讨论了第一次大功率试验的结果。
Accelerators can be used for hadrontherapy, a cancer treatment in which the patient is irradiated with hadron beams. For this purpose, the Italian foundation TERA proposes the “cyclinac”, composed of a high-frequency linac which boosts the hadrons accelerated by a cyclotron. The main research goal is to reduce the length of the linac by achieving higher accelerating gradients, without compromising the reliability of the accelerator. In order to measure the high gradient limitation, a 3 GHz single-cell gauge cavity has been designed, built and high-power tested by TERA. Results from the first high power test are presented and discussed in this paper.
