Superconducting cavities for SCL3

초록

The quarter-wave resonator (QWR) and half-wave resonator (HWR) superconducting cavities for the Rare Isotope Accelerator Complex for On-line Experiments (RAON) Superconducting Linac (SCL) 3 have been developed, tested, and installed in the linac. This paper presents the design parameters and fabrication processes for both QWR and HWR cavities. A brief overview of the vertical test setup, a detailed calibration, and cavity preparations for testing the superconducting cavities are described. Q curves for both the QWR and HWR cavities are measured as functions of the accelerating electric field. The performance of these cavities is successfully evaluated through vertical tests, and they are subsequently integrated into cryomodules for installation in the tunnel.
