Data

exp=cxif5315:run=147, 198 - dark

exp=cxif5315:run=162 - water sample

exp=cxif5315:run=169 - data sample

Detector: CxiDs2.0:Cspad.0

...

Difference of average dark images between runs 147-198 is small, 0.3 ADU, difference rms=0.6 ADU, this proves that CxiDs2.0:Cspad.0 is stable during 50 runs.

Image array averaging

1)  Download configuration file psana-cxif5315-cspad-ds2-NDArrAverage.cfg

2) To get average/rms/max over 10000 events data of run 169 use command:

psana -c psana-cxif5315-cspad-ds2-NDArrAverage.cfg -n 1000 exp=cxif5315:run=169

This command produces files with arrays of size (32x185x388)

• cspad-ndarr-ave-cxif5315-r0169.dat
• cspad-ndarr-rms-cxif5315-r0169.dat
• cspad-ndarr-max-cxif5315-r0169.dat

2) To get average/rms/max over 1000 events (skipping 5000) data for water sample of run 162 use command:

psana -c psana-cxif5315-cspad-ds2-NDArrAverage.cfg -s 5000 -n 1000 exp=cxif5315:run=162

Geometry alignment

In accordance with CSPAD Alignment, use geometry file:

/reg/g/psdm/detector/alignment/cspad/calib-cxi-ds2-2015-01-20/calib/CsPad::CalibV1/CxiDs2.0:Cspad.0/geometry/1-end.data

and array with image from file: cspad-ndarr-ave-cxif5315-r0169.dat

geo -i cspad-ndarr-ave-cxif5315-r0169.dat -g 1-end.txt
