COOLING STRUCTURE OF BEAM DUMP DEVICE, AND BUILDING FOR BEAM DUMP DEVICE INSTALLATION

摘要

PPROBLEM TO BE SOLVED: To provide a cooling structure of a beam dump device capable of efficiently cool a dumping target with a simple constitution. PSOLUTION: Main beam rods 11a, 11a of a floor 11 and a wall 12 of a building 10 at which beam dump devices 30 are installed and the main beam rods 12a are respectively joined to each other by joining steel wires 11b, 12b, furthermore cooling fins 13 are embedded into concrete of the floor 11, and the other end sides of coupling reinforcing bars 11j, 13j of which one end protrudes in the building 10 from the floor 11 are mounted on the main reinforcing bar 11a and the cooling fins 13 by welding or the like. These reinforcing bars 11j, 13j, and a cooling member 32 obtained by laminating pure iron plates 32P to support a dumping target 31 are coupled with flexible members 31 so that heat generated at the dumping target 31 by collision of charged particles has been dissipated.
