Description
We are pleased to invite you to the Joint Workshop of TYL/FJPPN and FKPPN, to be held in Hamamatsu, Japan.
- Date: May 18-21, 2026
- Place: ACT CITY HAMAMATSU Congress Center
The workshop consists of keynote talks, reports from institutions, award ceremonies, and project reports. The last day, May 21, is dedicated for an optional tour to the factory of Hamamatsu Photonics etc.
Keynote talks include the one from Hamamatsu Photonics to cover its technical development of photo-sensors.
This year, 2026, marks the 20th anniversary of France-Japan Particle Physics Laboratory/Network, and we plan to have a special session to celebrate.
The official hotel will be Hotel Crown Palais Hamamatsu, which is right across the street from the conference venue. Participants are recommended to book through our webpage. The charge will be announced in the registration page.
Excursion is planned on Thursday, May 21st. We visit a factory of Hamamatsu Photonics and the YAMAHA museum, and return to the Hamamatsu station at around 4:30pm. (The slots for the excursion are all booked as of Apr 23.)
The registration is open until April 17 extended to Apr 24, but the hotels and excursion are arranged in a first-come-first-served principle. The registration fee is 10,000 JPY, plus 3,000 JPY for those who join the optional excursion.
Organizers: Guillaume Batigne (SUBATECH), Marc Besancon (IRFU), Shoji Hashimoto (KEK, chair), Youngman Kim (IBS), Emi Kou (IJClab), Francois Le Diberder (IJClab)
Hosted by: High Energy Accelerator Research Organization (KEK)
Supported by: Japan Society for the Promotion of Science (JSPS) , Hamamatsu Photonics K.K.
