Here is a data library with PMT signals with different attenuators. The dynamic rage is from 1 pC to 2000 pC.

The data are collected using R5900 PMT with active dividers and 676 V. Patrick's LED 4 ns width and David's setup All figures are in “figures”.

Download data from https://atlaswww.hep.anl.gov/asc/phase2/data/, and then gunzip it. To make a plot for 1 trace, use

wget http://atlaswww.hep.anl.gov/asc/hepsim/hs-toolkit.tgz -O - | tar -xz;
python show_trace.py data/D1_traces_full.txt.gz 1

Data files in “data/*” have the name “D” that indicate attenuation strength for the light. We used 1 neutral density filter 50% (NDF50), and 1 neutral density filter x16 (NDF16)

1. D1 NDF16 + 6xNDF50
2. D2 NDF16 + 5xNDF50
3. D3 NDF16 + 4xNDF50
4. D4 NDF16 + 3xNDF50
5. D5 NDF16 + 2xNDF50
6. D6 NDF16 + 1xNDF50
7. D7 NDF16
8. D8 3xNDF50
9. D9 2xNDF50
10. D10 1xNDF50
11. D11 - no NDF
