  At RISP, superconducting cavity resonators to accelerate the various ions in high current are being developed. In particular, hal-wave resonator (HWR) will be used for β=0.12, f=162.5 MHz. Here we present the structural analysis of HWR, which includes the prediction of resonant frequency shift during the manufacturing and testing process, stiffening measures to minimize the shift, and the tuning mechanism. The processes of welding, polishing, vacuuming, cooling (to crygenic temperature)as well as Lorentz force, helium pressure fluctuation, microphonics, and interaction with the helium vessel and tuning system will be simulated optimizing the frequency shift.

  Abstract The RISP (Rare Isotope Science Project) accelerator has been planned to study heavy ion of nuclear, material and medical science at the Institute for Basic Science (IBS). It can deliver ions from proton to Uranium. The facility consists of three superconducting linacs of which superconducting cavities are independently phased and operating at three different frequencies, namely 81.25, 162.5 and 325 MHz. Requirement of the linac design is especially high for acceleration of multiple charge beams. In this paper, we present the RISP linac design, the superconducting cavity and the requirements of beam diagnosics.
