Optical measurement

2012-02-26 XPP CSPad metrology files from Chris Kenney:
2012-02-26-CSPAD-XPP-Configuration.pptx
2012-02-26-CSPAD-XPP-Metrology.xlsx
identically converted to the text format:
2012-02-26-CSPAD-XPP-Metrology.txt

Chris has changed the order of measurement: in stead of individual quads entire detector sensor positions are meaasured in changed order:

The new script
/reg/neh/home/dubrovin/LCLS/test_optical/convertOpticalToStandard.py
converts the new measurement to the standard file format:
2012-02-26-CSPAD-XPP-Metrology-standard.txt

Procedure and table of results

We calculate
S1 - 1st short side of 2x1
S2 - 2nd short side of 2x1
L1 - 1st long side of 2x1
L2 - 2nd long side of 2x1

dS and dL are the deviations of the 1st and 2nd corner along the short and long sides, respectively. The sign of all dS are chosen in order to provide correct sign for the tilt angle (the same direction for all 2x1 sensors).

Everything, excluding <dS/L> and angle(deg), are in micrometers.

  • All ds1, dl1 are well consistent (within +/-10um) with ds1, dl1, respectively
  • Angles of 2x1 are in the range from -0.76 to +0.18 degree.
  • All tilts are measured for entire detector. No need to apply any tilt for quads.
