We have developed indirectly cooled radiation-resistant magnet coils which can be loaded with larger current than before, which are required for upstream magnets of high-momentum beam lines to be constructed at the Hadron experimental facility in J-PARC. The indirectly cooled coils are made of solid-conductor-type mineral-insulation cables. In order to realize such a large -current indirectly cooled coils, heat problem at the end parts of the coils must be solved. For this purpose, we have carried out load tests using a test sample of the end parts, and have succeeded to load DC2000A to the test piece in vacuum by improving the emissivity and cooling structure of the end parts.

我们已经开发出间接冷却的抗辐射磁体线圈，其可以加载比以前更大的电流，这是需要在J-PARC的强子实验设施中建造的高动量束线的上游磁体。间接冷却线圈由固体导体型矿物绝缘电缆制成。为了实现这种大电流间冷线圈，必须解决线圈端部的发热问题。为此，我们使用端部的测试样品进行了负载测试，并通过改善端部的发射率和冷却结构，成功地在真空中将DC 2000 A加载到测试件上。
