“…Irradiation process. Gamma rays with varying energies can produce electrons and cause the formation of point defects and atom displacements when a sample is irradiated [6]. As shown in figure 2, the creation of vacancies and interstitial Frenkel pairs defects is primarily responsible for the alteration of material properties.…”

“…Neutrons exhibit an average energy range of 0.5-1 MeV, while gamma rays possess an average energy of approximately 1.1 MeV [5]. High-energy neutrons can cause atom displacements and collision cascades through interactions with lattice atoms, while gamma rays can induce point defects and atom displacements by generating secondary electrons with different energies [6]. Consequently, this radiation exposure can alter the microstructure of the lattice and impact important electrical properties such as critical current density and critical temperature.…”

High-temperature superconducting (HTS) magnets are crucial components in future fusion reactors, subjected to prolonged irradiation and complex mechanical conditions. While the irradiation sensitivity of HTS materials has been extensively studied, limited research has explored the effects of force conditions during irradiation. This study investigated the influence of irradiation on ReBCO tapes. An irradiation experiment was conducted utilizing a Co60 source irradiation device. Superconductor properties were evaluated through the induction method, while microstructure analysis was performed using X-ray diffraction (XRD) measurements. The results indicate that the critical current initially increases and subsequently decreases, while the critical temperature remains relatively stable. Furthermore, the bending degree during irradiation affects the critical current density, with a decrease in radius corresponding to a first increase and then subsequent decrease in critical current density. The force applied during irradiation exhibits a impact on the superconducting properties, underscoring the importance of considering force conditions in future investigations.
