S1 signal analysis 1) Rate vs amplitude 2) Charge vs amplitude

S1 signal: 1) rate vs amplitude �4 ✦ Goal: obtain the rate of muons (S1 signals) crossing the detector with no fields ✦ Next steps: • S1 rate vs different field conditions • Run with TPB response ~ PEN response • **Long run (6-7/11/2019): S1 rate stability** ✦ Run #1625 (18/10/2019) • Random trigger • Fields off • 30k events (250 subruns) • Time window: 1 ms • Sampling: 16 ns • PMTs at G=1e7 (20190912)
