J-PARC2024 — 4th J-PARC symposium

The J-PARC facility started its operation of a neutron beam facility in May 2008, a muon facility in September 2008, a hadron facility in February 2009, and a neutrino facility in April 2009. The output beam power of the accelerators is steadily increasing with the progress of the beam tuning and hardware upgrades. The output beam power of the rapid cycling synchrotron is reaching its design goal, 1 MW, and the main ring synchrotron achieved the operation for the neutrino facility at 500 kW. According to the symposium theme, "Futures of J-PARC, Futures by J-PARC", we will discuss the achievements from 15 years of J-PARC operation together with the progress in relevant fields around the world. We then will discuss future and upgrade plans of J-PARC and other facilities.
