Abstract

As a part of the ongoing XIIth plan project titled "R&D activities for high energy proton linac based spallation neutron source", the work on physics design of various subsystems of the injector linac and accumulator ring has been taken up at RRCAT, Indore. For the 1 GeV H- injector linac, physics design studies of individual systems have been completed, and the end to end beam dynamics simulation studies have been performed to ensure that the stringent beam dynamics criteria are satisfied for the optimized lattice. Physics design studies to optimize the linear lattice of the accumulator ring have also been completed. The design studies for the beam transport lines from the injector linac to the accumulator ring, and from the accumulator ring to target are currently in progress. This report describes the physics design of various systems of the injector linac and the accumulator ring.
