Abstract
Japan Atomic Energy Research Institute, JAERI, has been proposing the Neutron Science Project (NSP) which is composed of research facilities based on a proton linac and a proton storage ring with an energy of 1.5 GeV. In the proton storage ring, the pulsed beam from the linac is accumulated, and high intensity pulsed beam is produced for the neutron scattering experiment. The goal of the proton storage ring is to provide a short pulsed proton beam of less than 1 {mu}s with an average beam power of 5 MW with two rings. The study of the proton storage ring whose beam power is 2.5 MW has been performed. To achieve a beam power of 2.5 MW with an energy of 1.5 GeV, it is necessary to accumulate 2.08x10{sup 14} protons. When the beam injection is completed, accumulated protons are extracted from the ring during 1 turn. Lattice design for high intensity proton storage ring has been performed. 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. Each lattice has zero dispersion regions and long straight sections. The
