Description

Vertical tests of single-spoke resonator type 1 (SSR1) superconducting cavities were conducted in conjunction with high-pressure rinsing (HPR) simulations to evaluate and improve cavity performance. The quality factor (Q) was measured as a function of accelerating field (Eacc), Lorentz force detuning (LFD), and pressure sensitivity. Water droplet dynamics from a 0.5 mm diameter nozzle operating at 100 bars were analysed as a function of travel distance. An optimized HPR simulation was carried out by reducing the number of nozzles to enhance water pressure and maintain high surface coverage. The simula-tion results include detailed rinsing paths, meshing data, jet directions, and identification of untouched regions on the SSR1 cavity surface.
