Abstract :
A variable frequency H101 mode single-gap cavity has been made for the RCNP ring cyclotron. The frequency range is 22 to 33 MHz. Radially increasing voltage distributions of the acceleration system produce beam phase compression ratio of about 3. The cavity was excited up to 270 kV at 33 MHz in a preliminary test. A 20 inch cryopump evacuated the aluminium cavity chamber down to 1 × 10-7 Torr.
