Abstract :
The first rf cavity for the J-PARC (Japan Proton Accelerator Research Complex) 50 GeV synchrotron has been developed. In the cavity, magnetic-alloy (MA) cores are cooled by water directly. With the cavity, we have accomplished an acceleration field of more than 50 kV in 1.776 m cavity length. We show the design of the rf cavity and results of high-power tests.
