6. High power targets at J-PARC

Shunsuke Makimura (J-PARC/KEK)

03/09/2026, 09:00

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...

10. TOWARD RADIATION-TOLERANT TITANIUM ALLOY BEAM WINDOWS FOR MW-CLASS PROTON ACCELERATORS

Taku Ishida (High Energy Accelerator Research Organization (KEK)／J-PARC Center)

03/09/2026, 09:20

Beam windows used in MW-class proton accelerator facilities are subjected to severe thermal shock, cyclic stress, and radiation damage under intense pulsed beam operation. In the J-PARC neutrino beamline, a 0.4-mm-thick double-dome Ti-6Al-4V (Ti-64) beam window structure with He gas cooling between the two layers has been successfully operated; however, future higher-power operation toward the...

11. CONCEPTUAL DESIGN STUDY OF A BERYLLIUM TARGET FOR A FUSION NEU-TRON SOURCE FOR THE DEMO REACTOR

Kohki Kumagai (National Institutes for Quantum Science and Technology)

03/09/2026, 09:40

Design and development activities are currently underway with the aim of demonstrating power generation using a Fusion DEMO reactor in Japan in the 2030s. At QST Rokkasho, feasibility studies are being conducted on a fusion neutron source required for qualifying blanket performance for the Fusion DEMO reactor (hereafter referred to as DEMO-FNS).
Unlike A-FNS [1], DEMO-FNS is planned to...

28. - Design and offline qualification of a high-temperature niobium bent-foil target for SPIRAL1

Sophie Hurier (CNRS-GANIL)

03/09/2026, 10:00

The SPIRAL1 facility (Système de Production d'Ions Radioactifs Accélérés en Ligne) at GANIL (Grand Accélérateur National d'Ions Lourds) produces radioactive ion beams via the Isotope Separation On-Line (ISOL) method. Primary heavy-ion beams from ¹²C to ²³⁸U at up to 95 MeV/u currently impinge on graphite targets to induce projectile fragmentation. To extend and enhance isotope production,...

47. ANALYSIS OF IRRADIATION DAMAGE AND HIGH-HEAT LOAD IN THE BEAM DUMP MATERIALS TOWARD HIGH-POWER OPERATION

Dr Eiichi Wakai (Facility for Rare Isotope Beams, Michigan State University)

03/09/2026, 10:20

High-energy particles in accelerator facilities and nuclear research reactors utilize for the basic science, materials science, and engineering application and analysis in the world. In many facilities it is required to increase the operation power level and beam intensity for the requirements for them. In such facilities the beam intercept device such as beam dump and components of structure...
