Abstract :
In order to handle high intensity primary proton beam provided by Japan Proton Accelerator Research Complex (J-PARC), radiation-resistant beam lines have been constructed at Hadron Experimental Hall of J-PARC. The key technology of the radiation-resistant beam line is the radiation-resistant magnets. However all the peripheral devices of the magnets were designed and assembled as radiation-resistant ones since peripherals as well as magnets should be operated in very high radiation environment. In addition a safe operation and maintenance scheme of high intensity beam lines has been established based on the Chimney technology of radiation-resistant magnets including their peripherals. Then the beam lines in the Hadron Experimental Hall have been constructed with “radiation-resistant magnet system”.
