Abstract
The J-PARC rapid cycling synchrotron (RCS) has been delivered 300kW beam to both the MLF and the MR with high reliability and small beam loss for user operation. To realize simultaneously two kinds of beam shape which are required from the MLF and the MR, two pulse dipole magnets for injection painting were installed in the beam transport line from the Linac to the RCS. It was successful to make two kinds of beam shape with injection painting bump magnets and these added pulse dipole magnets. This injection painting system is used for user operation and works well for reduction of beam losses. Not only user operation but also high power beam test was performed, and beam power of 524kW for 35 second was achieved with low beam loss in the RCS. Almost all beam loss was localized at the ring collimator and the loss rate was about 2% and this was acceptable because design value of the beam loss was 3%. This power corresponds to 1.8MW for 400MeV injection in terms of the Lasslett tune shift. In this high-intensity trial, significant progress toward design output beam power of 1 MW was demonstrated. The status and progress of the RCS in J-PARC are presented.
