The European Spallation Source in Lund, Sweden, is a facility under the final stages of its commissioning process, with the first user program planned in 2027. The 600 m long proton linac underwent beam commissioning in Spring 2025 with first beams through the superconducting part of the accelerator and to the tuning beam dump. This last commissioning run aimed to test all the critical linac...
For the China Spallation Neutron Source (CSNS), the rapid cycling synchrotron (RCS) accumulates and accelerates the injection beam to the design energy of 1.6 GeV and then extracts the high energy beam to the target. The CSNS design beam power is 100 kW, with the capability to upgrade to 500 kW. By February 2020, the beam power had reached 100 kW, and through improvements, the beam power was...
The Japan Proton Accelerator Research Complex (J-PARC) linac has been operated with a design peak current of 50 mA since 2018, and several test operations have been performed at a higher peak current of 60 mA. Furthermore, an even higher beam current is being investigated for future projects at J-PARC. To achieve such high beam currents, it is essential to understand beam dynamics and minimize...
The Korea Multipurpose Accelerator Complex (KOMAC) has been operating a 100 MeV Proton Linear Accelerator (Linac) since 2013, supporting various research and industrial applications by providing proton beams to users through four regularly used beam lines. In addition to these, a neutron beam line has completed pilot operations and is set to begin user services. In parallel, maintenance and...
