First experiment on the mitigation of space charge force was carried out at the ISIS proton synchrotron, UK using the low output impedance harmonic cavity system, which was developed in this research programme. It was identified that the system is stable under the heavy beam loading, and the output impedance was derived from the measurement of the beam induced voltage. The obtained impedance (35 ohm) almost coincides with the design value, and also agrees well with the low-level measurement by the network analyzer. It is then expected to utilize the system for further study of the beam physics on the space charge force.

在联合王国ISIS质子同步加速器上，利用本研究方案开发的低输出阻抗谐波腔系统，进行了第一次减轻空间电荷力的实验。结果表明，系统在强束流作用下是稳定的，输出阻抗由束流感应电压的测量结果导出。得到的阻抗（35欧姆）与设计值几乎一致，也与网络分析仪的低电平测量结果一致。该系统可望用于束流物理对空间电荷力的进一步研究。
