Update: 30 September, 2023
The Cut Disk Structure (CDS) has been proposed for high energy linacs as an accelerating structure with high coupling coefficient. This structure was studied for applications both in proton and electron linear accelerators. An important point for the stable structure operation is a cool- ing capability. Real 3D thermal stress analysis has been performed by coupled simulations with MAFIA and AN- SYS codes. For this purpose a special interface code was developed. The temperature and thermal stress distribu- tions, operating and coupling modes frequency shifts for different operating regimes and coolingschemes were stud- ied. Results of the study are presented. For moderate and high heat loading the drift tube region is necessary. Spe- cial coupling windows shape is proposed to simplify CDS cooling for operation with high (more than 15 kW/m) heat loading.
