US-Japan Collaboration in the Construction of the BNL Superconducting Muon Storage Ring and Inflector

摘要

The US-Japan collaboration in the constraction of a BNL muon storage ring for the g-2 experiment (E821) is described from the viewpoint of Japanese collaborators.Japan has contributed in the production of described from the viewpoint of Japanese collaborators.Japan has contributed in the production of the pole pieces made of a vacuum-melted Ultra-Low Carbon Steel,Al-stabilized Nb/Ti superconductors for the superferric storage ring dipole coils,including technology transfer,and the development of a sophisticated superconducting inflector for muon injection.All of above items seem to be essential techniques to pursue accurate and detailed muon injection.All of above items seem to be essential techniques to pursue accurate and detailed muon g-2 experiments.Recent experimental results are also mentioned in the latter part of this report.
