“…The SHINE facility will build a superconducting linear accelerator with 8 GeV energy, three undulator lines, three beamlines, and the first 10 experimental stations [4]. The linear accelerator contains 75 superconducting cryomodules that have 600 1.3 GHz 9-cell TESLA-type superconducting cavities used for electron beam acceleration and two third-harmonic superconducting cryomodules, which have 16 3.9 GHz superconducting cavities used for linearizing the longitudinal phase space distortion of an electron bunch [5][6][7][8][9].…”

The Shanghai High Repetition Rate XFEL and Extreme Light Facility (SHINE) project will use 600 1.3 GHz fundamental power couplers, which are modified based on TTF-III power couplers, for continuous-wave operation with input power up to approximately 7 kW. The first batch of 20 sets of 1.3 GHz coupler prototypes was fabricated from three domestic manufacturers for the SHINE project. To better characterize the radio frequency conditioning phenomena for validating the performance of power couplers, a room temperature test stand was designed, constructed, and commissioned for the SHINE 1.3 GHz power couplers. In addition, a horizontal test cryostat was built to test the 1.3 GHz superconducting cavities, fundamental power couplers, tuners, and other components as a set. The results of these tests indicate that the 1.3 GHz couplers are capable of handling up to 14 kW continuous waves. Herein, the main aspects of the radio frequency design and construction of the test stand, along with the test results of the high-power conditioning of the 1.3 GHz couplers, are described.
