Optical measurements

Comments from Gabriel Blaj:

These replace the May 2014 versions and should be used for all experiments after September 24, 2014.

Changes in CXI-DS1:

  • Quad 3 (zero based counting) reworked; metrology updated in the attached file: "DS1-Metrology-Sept-24-2014"
  • Q3 Z values measured properly
  • Mikhail, please double check Q3 values for consistency
  • The other 3 quads (Q0, Q1, Q2) are unchanged (as in the previous metrology: May 15 2014).
  • Please note that this camera has been renamed. Possible new name: "CXI Camera 1"+ version number. Jason, could you please confirm the exact name and version.

As always, these excel metrology files are NOT FOR DISTRIBUTION to avoid user confusion. Only Mikhail?s curated version should be distributed and used.

Based on this comment the file 2014-05-15-CSPAD-CXI-DS1-Metrology-corr.txt is used and Quad 3 data is substituted.

Quads alignment

2015-06-02 cxih8015 run 0176

2015-06-02 quads alignment is done in geo using wide-ring image from exp=cxih8015:run=0176:

Aligned constants are in file /reg/g/psdm/detector/alignment/cspad/calib-cxi-camera1-2014-09-24/calib/CsPad::CalibV1/CxiDs1.0:Cspad.0/geometry/geometry-camera1-in-ds2-cxih8015-r176.data  (download).

2016-06-03 cxi06216 run 25

Chuck complained that in quads alignment with geo internal and external rings can't be fitted in concentric rings simultaneously.

Assumption is that Z coordinate is involved in this experiment:

 

ds = DataSource('exp=cxi06216:run=25:smd')
epics_var = Detector('CXI:DS1:MMS:06.RBV')

 

gives Z=-400  (D.1:MMS.0 -419.9924) so in this experiment sample-to-detector distance along Z should be 175mm

BTW, in g-optimized file /reg/d/psdm/cxi/cxi06216/calib/CsPad::CalibV1/CxiDs1.0:Cspad.0/geometry/25-end.data

Chuck uses Z= 578254um (question) Image obtained with this g-optimized file:

This image is used to set initial quad geometry in geo:

Progress with external rings "scale variation" was achieved using

  • central projection of pixel x-y coordinates to the constant Z plane and
  • applying small detector rotation ~0.5° around X and Y axes:

2016-06-15 cxil0216 run 150

Nadia Zatsepin approved to use for alignment runs 145 - 150 in cxil0216.

CSPAD Z position is estimated from Chuck's measurement:

 

ds = DataSource('exp=cxil0216:run=146:smd')
epics_var = Detector('CXI:DS1:MMS:06.RBV')

# D.1:MMS.0 -479.9976 
that gives Z=-480

Chuck's estimate:
Z-code z[mm]
   0   577
-200   380
-400   175
-------------- 
hence
-480   ~95mm

Test images:

  1. central rings
  2. external ring for tilt -0.3° around x
  3. external ring for tilt +0.3° around x (for cross-check)

Comments:  

  • cxil0216-r150 is very good for alignment - has bright internal rings and external from nozzle.
  • tilt -0.3° around x is required to inscribe external ring
  • plot (3) for tilt  +0.3° around x shows sensitivity to this effect - it looks like external ring has a horizontal offset.

To make consistent internal rinngs geometry with external (from nozzle?) tilt angles of entire detector were applied as shown below:

Image without x-y tilts

shows a few pixel offset for large radius ring.
