Description
A ultra-compact multi-particle superconducting cyclotron is currently under construction at the China Institute of Atomic Energy (CIAE). It is designed for the irradiation modification of high-temperature superconducting (HTS) tapes and medical isotope 211At production. An ion irradiation facility with online monitoring of temperature and critical current performance for HTS tapes have been designed. The facility comprises the following systems: 1) Beam transport system: This includes multiple sets of quadrupole magnets and an octupole magnet for beam shaping and modulating to get a big irradiation space with high uniformity. These efforts have culminated in a large-area, uniform beam spot (not smaller than 2×2 cm) at the irradiation terminal, with a uniformity better than 90%. 2) Ion irradiation terminal: This terminal features a high-precision roll-to-roll transport system, a high-vacuum system, an efficient cooling system, and a in house developed online monitoring system for temperature and critical current performance. It enables real-time monitoring of temperature changes during the continuous ion irradiation process, as well as real-time, non-destructive measurement of the critical current of HTS tapes. This capability facilitates dynamic research into the relationship between irradiation-induced damage and the degradation of HTS critical current performance. This facility combines advanced accelerator beam technology, high efficiency cooling system, high vacuum technology, and real-time monitoring and diagnostic techniques, providing a stable, efficient, and fully functional comprehensive experimental device for deeply revealing the mechanism of ion irradiation on the micro-defects and critical current performance of HTS tapes. This facility will be presented in detail in the paper.
