Abstract

A cut core configuration is adopted for the magnetic alloy cavities of J-PARC Main Ring to lower the R/Q to combat beam loading. The cut core surface is treated by "Diamond Polishing" which improves surface quality, therefore reducing the local temperature rise due to RF losses in operation. Long-term high-power tests have been performed for the J-PARC MR RF systems. The mechanisms of local heating, the cutting scheme, and the manufacturing method are presented.
