This project aims to complete radiation resistant magnet which is made from completely inorganic materials. For this purpose, we have continued the R&D works on the next two points ;1,R&D of Mineral Insulation Cable (MIC) with high current density2,R&D of various magnet parts which were made from completely inorganic materialsThe R&D works of the section 1 have already been completed by our previous works. However magnet parts of the section 2 are not ready even at the start point of this work (2003). Then we started the R&D works on ;1,Temperature switch,2,Water pressure switch,3,Interlock logic circuit,4 Mineral insulation signal cable :The R&D works for these parts have been made and reasonable good results have been obtained. Then we assembled the test magnet with these parts as well as MIC excitation coil and the long term test operation has been performed. In addition it, these parts were applied for the actual magnets of real operating beam lines of the KEK 12 GeV-PS.Now we can conclude it the magnet fabrication by completely inorganic materials is successfully done. In the last year of the project, we have investigated the wider scope of the magnet application to the real high intensity beam line. Then the setting up the magnets with beam monitors, vacuum ducts etc. etc.was tested. The beam line design with actual physics motivation has been performed I order to test the usefulness of the magnets at the real beam facility.

该项目旨在完成完全由无机材料制成的抗辐射磁体。为此，我们继续进行了接下来两点的研发工作；1、高电流密度矿物绝缘电缆（MIC）的研发；2、全无机材料制成的各种磁体部件的研发。第1部分的研发工作我们之前的工作已经完成。然而，即使在这项工作的开始点（2003 年），第 2 部分的磁铁部分也还没有准备好。随后我们开始了以下方面的研发工作：1、温度开关、2、水压开关、3、联锁逻辑电路、4矿物绝缘信号电缆：这些部分的研发工作已经完成，并取得了合理的良好效果。然后我们用这些部件组装了测试磁体以及MIC励磁线圈，并进行了长期测试运行。此外，这些部件还应用于KEK 12 GeV-PS实际运行束线的实际磁体。现在我们可以得出结论，完全无机材料的磁体制造已经成功完成。在该项目的最后一年，我们研究了更广泛的磁铁应用范围，以实现真正的高强度光束线。然后对磁体与光束监视器、真空管道等的设置进行了测试。已经进行了具有实际物理动机的束线设计，以测试磁体在真实束流设施中的有用性。
