Description

As a possible option for 200 MeV energy upgrade in Korea Multi-purpose Accelerator Complex (KOMAC), separated drift tube linac (SDTL) type is considered. In this study, a prototype drift tube for the SDTL is developed and tested. Based on the optimum cell parameters, detailed design of drift tube is derived. Especially, cooling channels of the drift tube consist of central and side channels to deal with RF heat load due to its long length. To verify the feasibility of the drift tube, prototype model is manufactured and its functional validity is confirmed by conducting coolant flow test in cooling channel and leak test for vacuum. In addition, multi-physics analysis on the drift tube including electromagnetic, thermal, and mechanical analysis are conducted. Characteristics of the drift tube in SDTL tank are assessed in the view of temperature rise, displacement, and frequency detuning.
