内容記述 |
An organic olefin-based thermosetting dicyclopentadiene (DCP) resin named TELENE was proposed as an impregnation material for Nb3Sn magnets to reduce the training. To verify the radiation resistance of the TELENE, gamma-ray irradiation experiments and three-point bending tests were conducted on the TELENE and the CTD-101K. The TELENE mixed with Gd2O2S powder was also applied for these measurements. The gamma-ray irradiation experiment was carried out up to nearly 20 MGy at room temperature using a Cobalt-60 source at the Takasaki Advanced Radiation Research Institute in Japan. For gamma irradiation in the absence of air, all resin samples were sealed in glass tubes and evacuated. The flexural strength and flexural modulus of each resin were measured by the three-point bending test before and after gamma-ray irradiation. The pure and mixed TELENE exhibits plastic deformation before the irradiation and can withstand larger strain than the CTD-101K. After irradiation, no decrease in flexural strength was observed up to 6 MGy for the pure TELENE and up to 17 MGy for the mixed TELENE. However, their strains at fracture decreased by more than 50% after 5 MGy irradiation. |
