Description
For future accelerator applications requiring high-intensity positron sources, we have been developing a rotating target system. The main technical challenges have been the rotary seal mechanism and the fabrication of a φ500 mm tungsten/copper disk. To address these issues, we designed a narrow-gap rotary seal structure and employed a shrink-fit technique for disk assembly, leading to the successful production of a prototype. Vacuum operation tests and thermal load tests were subsequently carried out, both of which demonstrated stable and favorable performance. In this presentation, we report on the design concept of the rotating target, the results of prototype fabrication and performance tests, and future prospects of this development.
