Overview
During the second week of June 2019, 5 counters were removed from the TAGH. These counters all had scintillators that were loosely connected to their respective light-guides and were believed to not be functioning properly. The initial 5 counters were the numbers 113, 116, 125, 144, and 161.
Initial State of the Counters
Two of the five counters had scintillators that were broken at the base, as is seen in the picture to the right. The other three counters had scintillators that were loose and no longer held by the epoxy to the light-guide. These damages are thought to be the result people bumping into them and not putting the protective caps over the scintillator part of the counter.
