Invitation from the Conference Chair
Masanori FUJINAMI (Chiba University)
On behalf of all members of the Japanese positron groups, it’s my great pleasure to chair the organization of the 20th International Conference on Positron Annihilation (ICPA20) and we warmly invite you to join us at Kagawa International Hall and Sunport Hall, Takamatsu, Kagawa, Japan on June 1-6, 2025. ICPA aims to cover fundamental and emerging trends in all aspects of positron and positronium annihilation, and to provide opportunities to exchange knowledge and promote collaborations.
ICPA19 was held as an online meeting due to COVID-19, but ICPA20 will be the first full face-to-face meeting in seven years, so that a lot of social programs will be also prepared to enhance interactions among researchers. In particular, we will encourage young researchers and PhD students to broaden their perspectives and expand the scope of their research. We hope that many researchers will gather and have a meaningful time in Takamatsu, a place of scenic beauty and plenly of fresh food.
We are looking forward to meeting you at Takamatsu, Japan.
Main Topics of the conference
- Fundamental aspects of positron & Ps
- Antihydrogen production & its fundumental studies
- Theory; Calculations of positron annihilation characteristics etc.
