Description

The KU–KEK–KAT collaboration produced a 1.3 GHz copper 9-cell cavity with the goal of establishing a domestic Nb cavity fabrication flow in Korea, and performed pre-process verification under the same conditions as the Nb fabrication procedure. Prior to fabrication, the reliability of the actual manufacturing was enhanced through EM simulations and engineering simulations using CST, and the fabricated cavity was evaluated by measuring the resonance frequency with a network analyzer and tuning the frequency using a tuner. For this purpose, we construct new antenna by redesigning and simulating 1-cell measurement antenna to 9-cell antenna for room-temperature measurement, and all measurements were measured with this antenna. In the initial π-mode after fabrication, the resonance frequency was measured to be 1.275 GHz, which corresponds to about 90% of the design frequency of 1.3 GHz, and after tuning it was confirmed to increase to 1.29 GHz.
