  Quarter-wave resonators (QWR), Half-wave resonators (HWR)are adopted for the low energy superconducting linear accelerator of RAON, two types Single spoke resonators(SSR type1, SSR type2) are for the High energy. The performance tests for the prototypes of QWR, HWR cryomodules are carried and the designed goals are achieved. About 130 QWR/HWR cavities and 56 modules shall be produced and tested within 2020. For the cryogenic tests, facilities are constructed with 5 module-test bunkers and 5 cavity-test pits. First one cryomodule with 3 SSR1 cavities will be tested in this year and two cryomodules with 6 SSR2 cavities will be tested within the first quarter of the next year.

The Rare Isotope Science Project (RISP) in the Institute of Basic Science (IBS), Korea, is developing and con-structing the multi-purpose linear accelerator at the north side of Daejeon, South Korea. RISP accelerator (RAON) is composed with low-energy region (SCL3) and high-energy region (SCL2), and low-energy region is made with quarter-wave resonator (QWR) and half-wave resonator (HWR) when high-energy region is made with single spoke resonator type-1 (SSR1) and type-2 (SSR2). This paper shows about the initial resonance issues of QWR superconducting (SC) cavity during cold test and SRF disturbance measurement. Afterwards, this paper shows the modal analysis and vibration test of QWR SC cavity.
