Description
J-PARC has three proton accelerators and three research facilities with using MW-class high power proton beams. Each experimental facility is equipped with beam-intercepting devices, such as targets and beam windows, to generate secondary particles; the survivability of beam-intercepting devices, such as target and beam window under intense beam irradiation is a key factor limiting the achievement of higher beam power.
In April 2026, the Beam Technology Development Section was established to address the development of common technologies across all facilities. This presentation reports on the high power targets at J-PARC and the activities of the newly established Beam Technology Development Section.
