Power-handling capability of the annular coupled structure linac for the JAERI/KEK joint project

Yamazaki, Yoshishige; Hayashizaki, Noriyosu*; Paramonov, V.*

The power-handling capability is the critical issue for a high intensity proton linac of normal-conducting coupled-cavity type. In the JAERI/KEK Joint Project, a coupled-cavity linac with the Annular Coupled Structure (ACS) has been developed in order to operate with 3 % duty factor. The ACS accelerating module consists of two ACS tanks and one bridge coupler. The cooling water circuits in the ACS cells ensure the effective and uniform cooling, stabilizing the deviation of cell frequencies. Some of excited cells in the bridge coupler are equipped with fast movable tuners to tune the cavity to the operating frequency. The results of thermal and structural analysis are presented, together with the RF parameter analysis, for different linac regimes. For the adopted ACS module design, the results of the analyses suggest that the operation with the heat loading of up to 90 kW/m is possible, which is corresponding to the 15 % duty factor operation.
