A design study of the proton storage ring for the Neutron Science Project at JAERI

The goal of the proposed Neutron Science Project (NSP) at JAERI is to provide a short pulsed proton beam of less than 1 /spl mu/s with an average beam power of 5 MW. To achieve such purpose, a proton storage ring operated at 50 Hz with 4.17/spl times/10/sup 14/ protons per pulse at 1.5 GeV is required. Two kinds of a lattice are examined as a lattice of the proton storage ring for neutron science project. One is FODO lattice and the other is Triple Bend Achromatic (TBA) lattice. This paper describes preliminary results of the lattice design for the proton storage ring.
