Abstract
On January 27, 2009, protons were accelerated by 50 GeV Proton Synchrotron (50 GeV-PS) up to 30 GeV, at which we will operate the PS at the first phase of the project, and successfully extracted to Hadron Experimental Hall in Nuclear and Particle Physics Facility and transported to the beam dump [1]. Hadron Experimental Hall is one of the two facilities at 50 GeV-PS and utilizes the various kinds of secondary particles generated by protons. To make plenty of secondary particles by the high intensity proton beam available for experiments, many methods of handling the high intensity beam have been developed for this facility. In particular, a firm radiation shield was constructed and magnets that were hard to break and easy to be replaced, in case of trouble in the high radiation area, were produced.
