Abstract
The J-PARC Project 3-GeV proton synchrotron is designed to accelerate 8.3 × 1013 protons per pulse at a 25 Hz repetition rate for the injection energy of 400 MeV. The incoming beam emittance of the 400-MeV linac is 4π mm mrad and the acceptance in the 3-GeV synchrotron is 324π mm mrad in both the horizontal and vertical planes. Painting injection system is designed to fit in the FODO structure, which has rather short drift space. The bump orbit for painting injection is designed to have a full acceptance of the circulating orbit through the injection period. A full-acceptance bump orbit will enable both correlated and anti-correlated painting injection.
