- Ben started analyzing the THU base. Here is his Calculation on all three PMT bases
- Zhihong shared pictures of the super-module being assembled at THU: pic0, pic1, pic2; He will also send a new PMT base design diagram (for the super module) so we can study its possible gain shift in advance
- Zhihong will look if there are old PMTs with the same base as the 2023 Hall C beamtest, and will do a bench test to study the gain shift if any such PMT/base is found.
- Xiaochao shared a rough draft of the beam test report. Still need to wrap up some calculation, and need someone to double check all numbers.

The EC weekly meeting minutes prior to FY22 beam test was hosted on an old-fashioned HTML page: All EC meetings 2013-2022
