The High Intensity Proton Accelerator facility (HIPA) at the Paul Scherrer Institute, Villigen, Switzerland will celebrate its 50th year of operation in 2024. This contribution provides insights into the facility’s operational history, current status, and forthcoming upgrade strategies. At present, the focal point rests on the RF-upgrade program of the Injector 2 cyclotron. This initiative is one of the main pre-requisites for reaching a beam current of 3 mA. First results about the operation with one new 50 MHz resonator in Injector 2 will be presented.

The 3-GeV RCS of J-PARC now operates at high-intensity to nearly the designed 1 MW beam. The beam loss and the corresponding residual radiation is one of the key limitations against beam intensity ramp up. Recently, by a series of beam studies and feedback from numerical simulations, we have well mitigated the beam loss to a minimum level and also reduced the beam emittances for beam operation to the spallation neutron source as well as to the main ring. The residual beam loss at the designed 1 MW beam power occurs mostly due to the unavoidable foil scattering beam loss during multi-turn injection, while other beam loss sources have been well mitigated to realize a stable and higher availability beam operation at a nearly 1 MW beam power.
