Description

The pre-production development of the SSR2 cavity and cryomodule for the RAON SCL2 superconducting linac is in progress. The 325 MHz, βopt = 0.51 cavity is designed for 4.1 MV accelerating voltage and Eacc ≥ 8.7 MV/m at 2.05 K. RF and mechanical analyses confirm acceptable peak fields, pressure sensitivity, and Lorentz-force detuning. The fundamental power coupler is de-signed for 7 kW CW operation and is planned to be tested up to 20 kW CW in travelling-wave mode. The six-cavity cryomodule incorporates thermal intercepts, a 50 K ther-mal shield, and multilayer insulation to reduce cryogenic heat loads. The 2 K heat-load design goal is 100 W, con-sisting of 20 W static and 80 W dynamic load. Fabrica-tion of the first pre-production cavity is underway.
