2024/08/27: Annoucement of PHITS Workshop + Intermediate Course in Japan on Feb 18-21, 2025
Recently, PHITS has been used by more than 10,000 researchers from over 70 countries in a wide range of research areas, including nuclear engineering, medical physics, radiation biology and protection, and cosmic-ray research. However, communication between PHITS users is not very active because they generally attend conferences specific to their own research fields and rarely have the chance to meet other PHITS users studying different fields.
To address this issue, we have decided to organize the first PHITS International Workshop and Intermediate Course in Tokai, Japan, creating an opportunity for PHITS users from various research fields and countries to come together. Therefore, we encourage you to participate in this event and present the results of your study using PHITS on any topic. We look forward to seeing you in Japan this winter. Please check the workshop's website in more detail.
