On November 1 and 2, 2025, we held an “OSECHI Development Retreat” at University of Toyama. The OSECHI project normally holds regular meetings online, but about once a year we bring members together in person for a concentrated push on development.
This retreat included a first in-person meeting with the University of Toyama members who joined the project this year, and discussion was lively. On the development side, we redesigned OSECHI’s PCB and worked hands-on through how to combine the electronic parts and configure the initial setup, completing five OSECHI detectors by the end. The retreat further strengthened collaboration among members and marked an important step forward for future development.
