为聚变装置（如新提出的聚变点火研究实验（FIRE））建造的磁体需要高度可靠，特别是在高辐射环境中。由于绝缘材料对高辐射剂量的敏感性、低温下的脆化以及其可制造性的限制，绝缘材料通常是超导磁体设计中的薄弱环节。一种能够真空浸渍具有所需性能如长适用期、高强度和优异的电完整性并且还提供高抗辐射性的绝缘系统将极大地改善磁体性能并降低制造成本。利用氰酸酯化学物质与其它已知的抗辐射树脂（例如双马来酰亚胺和聚酰亚胺）结合，已经开发了一类新的绝缘材料。这些材料已被证明可以满足下一代设备（如FIRE）的苛刻要求。辐照后测试到的水平。
Magnets built for fusion devices such as the newly proposed Fusion Ignition Research Experiment (FIRE) need to be highly reliable, especially in a high radiation environment. Insulation materials are often the weak link in the design of superconducting magnets due to their sensitivity to high radiation doses, embrittlement at cryogenic temperatures, and the limitations on their fabricability. An insulation system capable of being vacuum impregnated with desirable properties such as a long pot-life, high strength, and excellent electrical integrity and which also provides high resistance to radiation would greatly improve magnet performance and reduce the manufacturing costs. A new class of insulation materials has been developed utilizing cyanate ester chemistries combined with other known radiation-resistant resins, such as bismaleimides and polyimides. These materials have been shown to meet the demanding requirements of the next generation of devices, such as FIRE. Post-irradiation testing to levels th...
