1st Announcement
Dear Colleagues,This is the first announcement of the 8th High Power Targetry Workshop, which will be hosted by RIKEN and J-PARC and willtake place at RIKEN Nishina Center for Accelerator-based Science, Wako, Saitama, Japan, from Nov. 6th to Nov. 10th,2023.
The HPT Workshop brings together scientists and engineers from the international community for particle accelerator targetry.
Applications include neutrino facilities, neutron facilities, radioactive ion beam facilities, material irradiation facilities, accelerator
driven systems, and precision experiments for rare processes. This workshop will be conducted in-person.

Participants are invited to submit their contributions covering one of the following topics orrelated subjects. Themes for the workshop include:
1.

R&D to support concepts
R&D: target physics, testing and material

2.

Radiation damage in target material and related simulations
Radiation damage simulation and databases

3.

Post-irradiation examination
PIE results, feedback to R&D and design, experimental technologies

4.

Target design, analysis, and validation of concepts
Target design and optimization by numerical simulations

5.

Target facility challenges
Facility radioprotection, remote handling, lifecycle challenges

6.

Construction, fabrication, inspection, quality assurance
Integration, feedback/experience

7.

Operation of targets and beam dumps
Operational experience, instrumentation and monitoring, maintenance8.

Multipurpose use of targets and beam dumps
Beam dump facilities for irradiation and particle generation

Time will be available for open discussion, and we would welcome suggestions of suitable topics. For those who are interested inestablishing inter-laboratory collaborations, we may provide support to organize satellite meetings.
