Description
J-PARC is a multipurpose experimental facility and has high intensity proton accelerators of a linac, a 3-GeV rapid cycling synchrotron (RCS), and a 30-GeV synchrotron. The linac and the following RCS provide a high power proton beam for driving muon and neutron sources at Materials and Life Science Experimental Facility (MLF) through a 300-m-long beam transport line. In 2024, long-term high power beam operation at the design value of 1 MW was achieved through continuous beam studies. The beam studies of the linac and the RCS are continued for further stable operation and a beam power upgrade beyond 1 MW towards future upgrades of J-PARC, including MLF second target station (TS2). Design studies of a new 3-GeV proton beam transport line to the TS2 are also ongoing. In this presentation, we show the operational status and recent studies for future upgrades of J-PARC.
