Abstract :
Continuity R&D work is reported here on the radiation resistant magnets for the Japan Proton Accelerator Research Complex (J-PARC). The main accelerator of the J-PARC is the 50 GeV-15 mA proton synchrotron (50 GeV-PS) with beam power of 750 kW. The radiation resistant magnet is the key technology to realize the external beam lines and experimental facilities of the J-PARC 50 GeV-PS. The radiation resistant technologies we have selected for the J-PARC are; (1) Polyimide Resin Insulation (PI) for up to 108 Gy and, (2) Mineral Insulation magnet Cables (MICs) with larger cross sections for higher radiation dose up to 1011 Gy. Approximately 20 polyimide insulation magnets and 10 MIC magnets are designed for the external beam lines of the 50 GeV-PS. The fabrication of those magnets has already started in 2005 and will continue until the end of 2007
