In 2023 J-PARC Main Ring achieved 750kW beam power for T2K neutrino experiment. The 750kW is the initial design value of MR and it means to reach a great milestone. In this talk, I will briefly introduce the key technologies needed to achieve this 750kW. One of the key technologies is the injection and extraction systems. The kicker magnet and power supply, septum magnet and power supply used...
The Rare isotope Accelerator Complex for ON-line experiments (RAON) is a heavy-ion accelerator for researches using Rare Isotopes (RI) as a major research facility in Korea. It can deliver ions from hydrogen (proton) to uranium. Protons and uranium ions are accelerated up to 600 MeV and 200 MeV/u respectively. It can provide various rare isotope beams which are produced by isotope separator...
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. As the second phase of the CSNS, CSNS-II will achieve a beam power on the target of 500 kW. The injection energy of CSNS-II will be increased from 80 MeV to 300 MeV and the...
To meet the 500kW beam power requirement of China spallation neutron source project Phase-II (CSNS-II), an external antenna RF-driven negative hydrogen ion source has been developed. It has been put into commissioning on China spallation neutron source (CSNS) accelerator since September of 2021. In the last two run cycles, it has operated for 315 days and 323 days respectively, with 100%...
Since neutrons are secondary particles, their efficient use is important in applications. Even neutrons, which have no electric charge, can be deflected by magnetic fields due to their magnetic dipole moment. Transport and manipulation of neutron beams using magnetic fields will be discussed.
There are two research reactors at the Institute for Integrated Radiation and Nuclear Science, Kyoto University (KURNS). Kyoto University Research Reactor (KUR) of one of the reactors, which has a thermal output (5 MW), is scheduled to be shut down in May 2026. The KUR has been used for many years as a neutron source for collaborative research, and we are considering the construction of a...
The CSNS is an accelerator-based multidisciplinary user facility operates at a stable beam power of 140 kW since October 2022, which is 40% higher compared to the designed value. The upgrading project of CSNS (CSNS-II) is in progress, and the missions associated with linac include increasing the output energy to 300 MeV by employing superconducting accelerator and the peak current to 50 mA. A...
