Optical measurement
Update
- 2013-06-11 Modify script
convertOpticalToStandard.pyfor indexing of rotated CSPAD - directly generated center_global/0-end.data constants
- deployed to sxr65713
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
- 2013-01-29-CSPAD-Metrology-XPP.xlsx- file from Chris Kenney
- 2013-01-29-CSPAD-XPP-Metrology.txt - text version of the file. Only Quad 0 in this file is changed comparing to 2013-01-29-CSPAD-XPP-Metrology.txt
- Use script
convertOpticalToStandard.pyto produce 2013-01-29-CSPAD-XPP-Metrology-standard.txt
- Numeration of quads is still wrong by 180 degree... So, change the numeration in 2013-01-24-CSPAD-XPP-Metrology-standard.txt
- Apply the same corrections of a couple of corners:
Q1,p3: 12 21331 47024 47 -> x+200, y-200 12 21531 46824 47 Q3,p5: 24 90849 68979 218 -> x+300, y-200 24 91149 68779 218
Or the same correction in 2013-01-29-CSPAD-XPP-Metrology.txt (2013-01-29-CSPAD-XPP-Metrology-corr.txt):
Quad 1 < 24 177872 164109 218 -> x+300, y-200 > 24 178172 163909 218 Quad 3 < 31 90737 42743 37-> x+200, y-200 > 31 90937 42543 37
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
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
Quality check parameters for the perfect measurement:
- S1=S2, L1=L2 - the 2x1 sides should have equal length and width,
- D1=D2 - the 2x1 diagonals should be equal,
- dS1 = dS2 = 2*dL1 =2*dL2 - tilt angle should provide consistent deviation for all corners,
- dD=0, d(dS)=0, and d(dL)=0 - within precision of measurement.
Everything, excluding <dS/L> and angle(deg), are in micrometers.
