22/10/2017 Start: 01:26 Run: 037 Stop: 11:01 Run: 039 List mode: 171022_0126_bck_*.dlt Root file: 171022_0126_1101_bck.root Observations: 1. The noise in 3He tubes has been effectively suppresed (compare figure of BRIKEN spectrum in attachment with similar figures of previous runs) 2. The 252 Cf source used immediately before has activated something as can be deduced from the change of rate in the D4 detector compared to G7 (standing on the floor) see picture below. The effective half-life of the activation is T1/2=71.8min (see figures in attachment)
