Dear Colleagues,
This is the second announcement for the 32nd World Conference of the International Nuclear Target Development Society (INTDS2026), which will be hosted by RIKEN and held at the RIKEN Nishina Center for Accelerator-based Science in Wako, Saitama, Japan, from August 30th to September 4th, 2026.
We are pleased to announce that a joint session will be held for the first time with the 20th Workshop on Targetry and Target Chemistry (WTTC20) (https://wttc20.ric.u-tokyo.ac.jp ) on August 31st, 2026.
WTTC focuses on solid, liquid, and gas targets for accelerator-based radionuclide production, as well as post-irradiation chemical processing.
This joint session aims to foster deeper discussion and interaction on the research and development between beams and targets and to promote cross-disciplinary exchange among the communities.
This workshop will be conducted in person.

· Preparation of radioactive targets
· Preparation of liquid and gas targets
· Beam charge strippers (i.e., foil, liquid, gas, plasma)
· Targets for high-intensity beams
· Targets for special applications (e.g., medical, industrial, controlled fusion)
· Target characterization
· Target recycling and disposal
