Optical measurement

Note

Chris informed me that in this measurement the detector was rotated by 180 degree, that requires to interchange of Q0 with Q2 and Q1 with Q3 parameters. It was done in 2013-01-24-CSPAD-XPP-Metrology-standard.txt file.

...

Note from Chris:
The new metrology file is attached.  It has some unique characteristics.
1) all the positions are the same for 3 of the 4 quadrants
2) only the values for Quad 0 have changed.
3) this was done by aligning the entire detector to about 30 microRadians by hand.
4) This was checked by recording the positions of a few points on the other three quads
5) The slight rotation between last weeks and this weeks metrology can be taken out using these extra data points

Procedure

...

...

  • txt - text version of the file. Only Quad 0 in this file is changed comparing to 2013-01-

...

...

  • Use script convertOpticalToStandard.py to produce 2013-01-

Then:

  • Image Added
  • Numeration of quads is still wrong by 180 degree... So, change the numeration in
  • converted to the standard for quads file format,
  • quads numeration is changed by 180 degree rotation (swapped data for Q0 with Q2 and Q1 with Q3) in:
    2013-01-24-CSPAD-XPP-Metrology-standard.txt Image for all quads after correction:

QC procedure and results

  • Apply the same corrections of a couple of corners:

QC procedure and results

We calculate
S1 - 1st short side length of 2x1
S2 - 2nd short side length of 2x1
L1 - 1st long side length of 2x1
L2 - 2nd long side length of 2x1
We calculate
S1 - 1st short side length of 2x1
S2 - 2nd short side length of 2x1
L1 - 1st long side length of 2x1
L2 - 2nd long side length of 2x1
D1 - 1st diagonal of 2x1 between corners 1 and 3
D2 - 2nd diagonal of 2x1 between corners 2 and 4
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).
<dS/L> - the tilt angle of 2x1 averaged over two sides in radians.
angle(deg) - the same angle in degrees.
dD = D1 - D2
d(dS) = dS1 - dS2
d(dL) = dL1 - dL2

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

  • In Quad 1, pair: 3 mis-measured x and y - correction is applied as discussed below.
  • In Quad 3, pair: 5 mis-measured x and y - correction is applied as discussed below.
  • All other measurements are consistent within measurement precision about 10um
  • Angles of 2x1 are in the range from -0.64 to +0.38 degree.
