Muon Telescope with 2" PMT
The muon telescope was built with a 2“ PMT R1332 as the middle (signal) PMT. 2” PMT 8575B was the top of the telescope, and 1“ PMT 18 was the bottom of the telescope. The total number of events was 16358 for a run that took 4.8 days.

The sharp cut-off around 8.2 V suggests this was the full-scale; however, the full-scale was set to 16 V.

Based on the calculated of this post, the energy of the peak around 120 nVs should be 5.6 MeV.
