Belle II Trigger/DAQ Workshop 2025

22 Oct 2025, 08:00 → 24 Oct 2025, 20:40 Asia/Tokyo

大セミナー室 (Large seminar room) (大阪公立大学文化交流センター　(OMU Academic Extension Center))

The annual Belle II Trigger/DAQ workshop has been resumed.

The workshop is held in a hybrid-style with both face-to-face and remote connection. 

The main topic of the workshop is to discuss target during RUN2 and the possible improvement and development for "Long Shutdown 2(LS2)", which has been extended to 2032. The discussion includes the application of machine learning for the automatic optimization of TRG/DAQ condition in beam, and the approach for the triggerless DAQ.

Host: Osaka Metropolitan University, OMU NITEP, KEK

Organizers: Masako Iwasaki (Osaka Metropolitan University), Eiichi Nakano(Osaka Metropolitan University), Taichiro Koga (KEK), Satoru Yamada (KEK), Mikihiko Nakao (KEK)
