结合日本强子设施（JHF）项目，KEK 继续开发新型抗辐射磁体线圈。其中一个主要项目是设计和生产具有更大最大电流的矿物绝缘电缆（MIC）。我们已经开发出具有方形截面空心导体的2000A级MIC。使用该 MIC 制作了一个示例磁体线圈。其稳定性和可靠性测试正在进行中。我们现在正计划开发3000A级的MIC。另一个计划是研发一种完全无机的缠绕绝缘材料，该材料可以像普通类型的预浸渍环氧树脂的玻璃纤维带一样使用。经过对多种胶带和粘结剂组合的机械强度和电绝缘性测试后，我们发现了一种预浸渍无机水泥的纯（99％）氧化铝纤维带，适合热固化后的磁体线圈绝缘体。 >
In connection with the Japanese Hadron Facility (JHF) project, the development of new types of radiation-resistant magnet coils has been continued at KEK. One major program is the design and production of a mineral insulation cable (MIC) with a larger maximum current. We have already developed a 2000A-class MIC having a square-cross-section hollow conductor. A sample magnet coil was fabricated with this MIC. Tests of its stability and reliability are under progress. We are now planning to develop a 3000A-class MIC. The other program is R/D work on a completely inorganic wrapping insulation material which can be used like the usual type glass-fiber tape pre-impregnated with epoxy-resin. After tests of the mechanical strength and electric insulation of many combinations of tapes and bonds, we found a pure (99%>) alumina-fiber tape pre-impregnated with inorganic cement that is suitable for a magnet coil insulator after thermal curing. >
