2013-01-24 XPP CSPad metrology file from Chris Kenney:

It is clear that quad 2 p.21 (12 in standard numeration) is dy=1mm off. It is corrected in the 2013-01-24-CSPAD-XPP-Metrology-standard.txt file.

QC procedure and 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.

Comparing deviations of dS1 and dS2, and dL1 and dL2, we found:

  • In Quad 3, pair: 3 mis-measured x and y about 200um - Use it as is (do not know which corner(s) should be corrected).
  • All other measurements are consistent within +/-10um
  • Angles of 2x1 are in the range from -0.64 to +0.38 degree.
