| Research Abstract |
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.
