双谐波操作，其中加速腔由基波和二次谐波射频电压的叠加驱动，可用于日本质子加速器研究中心（J-PARC）快速循环同步加速器（RCS）中超高强度质子束的加速。然而，要实现双谐波加速，需要对谐波进行精确、快速的电压控制。我们为 J-PARC RCS 开发了双谐波自动电压控制系统。我们描述了设计和实现的细节。系统的各种测试均使用 RCS 射频系统进行。此外，初步的光束测试已经完成。我们报告测试结果。
The dual-harmonic operation, in which the accelerating cavities are driven by the superposition of the fundamental and the second harmonic rf voltage, is useful for acceleration of the ultrahigh intensity proton beam in the rapid cycling synchrotron (RCS) of Japan Proton Accelerator Research Complex (J-PARC). However, the precise and fast voltage control of the harmonics is necessary to realize the dual-harmonic acceleration. We developed the dual-harmonic auto voltage control system for the J-PARC RCS. We describe details of the design and the implementation. Various tests of the system are performed with the RCS rf system. Also, a preliminary beam test has been done. We report the test results.
