|
Uwe found out, that there was some common ground effect between 90 and 145 degree detectors. after moving the grounds, we could record much more nicer (Gaus
shaped) peaks in the spectra. Now we continue with this settings |

Wed Apr 8 23:02:24 2020, Laszlo, General, lmd to measurement pairing list,
|
I use the following list of lmd files combined to a single root file for each measurement.
It is very important to highlight that sometimes the trigger==1 data got corrupted,massive number of trigger==2 like events appear on the detector as trigger==1
signal, because the gas jet target didn't switch off after its normal phase (gas jet remains ON during injection. Maybe some gas jet issue, maybe some |
