Comparison of XGT data between before/after shipment to NSBF


Description of the data

I have investigated XGT data of BFEM, to see if there are any siginficant changes before/after shipment to NSBF. The data are taken by Dave Lauben and converted into ROOT file by Heather Kelly. There are six data files (each of them is 10-minutes run), three were taken before the shipment and three after the shipment. For more detail, see NSBF Tesging.


Pedestal

I derived XGT histograms and looked at the pedestal for each of XGTs. Results are shown below. No change was seen during the same run. Before/After the shipment, pedestals changed by a few channel. This can be negligible because up to 1000 ADC channel can be used for XGTs.

PHA Histogram

I compared the XGT PHA histograms before/after the shipment for each scintillator. Derived histograms are shown below. The statistics are rather poor, because integration time was only 30 minutes. However, as far as I investigated, no significant change is seen for MIP peak position.
