Abstract:
After linac energy and intensity upgrade to 400MeV and 50mA respectively, J-PARC linac were ready for equivalent 1 MW beam power from RCS in 2014. The next milestones 1.2 and 1.5MW from RCS are relying on feasibility and property of increase of peak current to 60 mA and the pulse width to 600us in linac. Beam studies were carried out at linac to study the initial beam parameters from ion source/RFQ, to find the optimized lattice and matching, to clarify beam loss source and to mitigate the loss/residue dose for the power upgrade.
