<h3><span class="mw-headline" id="Upcoming_Runs">Upcoming
Runs</span></h3>
<p>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.

total of 12.4 W for the entire detector or 0.10 W per
3 mm × 3 mm square SiPM chip.
