An RF-driven $\mathrm{H^-}$ ion source has been developed and put into commissioning at the China Spallation Neutron Source (CSNS). The ion source features a silicon-nitride plasma chamber and an external antenna structure. It has demonstrated a maintenance interval exceeding 7,500 hours with nearly 100% availability.To achieve the goal of delivering a 500 kW beam power to the spallation...
CEA Paris-Saclay has been engaged in the development of high-intensity proton sources since the early 1990s, beginning with the SILHI ECR ion source, designed to inject beam into the IPHI accelerator. Still in operation today, SILHI has demonstrated long-term stability and reliability. To improve compactness and ease of maintenance, a redesign of the plasma chamber was initiated. This effort...
During the long-term shutdown in FY2021, major upgrades of the main magnet system in the J-PARC Main Ring (MR) were carried out, including the installation of new power supplies, rearrangement of existing PSs, restructuring of magnet families, and cable re-wiring, contributing the beam extraction repetition period for the T2K experiment shortened from 2.48 s to 1.36 s, enabling operation at...
