Upcoming Runs

Beni asked if the Start Counter would be used for upcoming runs. If removed it can be stored in the Hall: it has its own stand and its own crate that accommodates the detector on its stand.

Measuring SiPM Power Consumption

Beni looked at current draw from the bias voltage supplies to estimate power use by the SiPMs. He find a total of 12.4 W for the entire detector or 0.10 W per 3 mm × 3 mm square SiPM chip.
