DEVELOPMENT OF A RADIAL COMPRESSED SEAL AND ITS REMOTE HANDLING DEVICES

This paper reports the design of a radial compressed seal and its remote handling flange used in the NP-hall of J-PARC. This facility will be handled a high intensity proton beam of 3x10 14 ppp accelerated by 50GeV. The power of a primary proton beam will be about 100 times greater than the currently slow extraction facility at KEK 12GeV-PS. The radial seal ordinary used as the seal of high viscous fluid was developed as a new flange system for a connection of vacuum beam pipes. Presently two flange devices were developed by each fastening mechanisms. The sealing capacity of the connecting device is reached with <10 -10 Pa.m 3 /sec.
