| Research Abstract |
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.
