Optical measurements

E-mail from Gabriel:

Today we measured the metrology for the MEC quad.
Mikhail, could you please update the metrology? It should be applied to all experiments between April 3rd 2015 and June 3rd 2015.
As always, please use only the metrology files provided by Mikhail and not the raw file attached here.
Thanks,
Gabriel and Philip

Alignment check with rings

exp=meci0215:run=55 detector is tilted, so orthogonal to the beam projection does not work well:

 

Deployment

Parameters for geometry (and old style center and tilt) are available in

Archive: /reg/g/psdm/detector/alignment/cspad/calib-mec-2015-04-03/calib/calib/CsPad::CalibV1/MecTargetChamber.0:Cspad.0/geometry/

  • 0-end.data   - non-corrected
  • 1-end.data   - corrected 68um offset for point 24.

Deployment: for all experiments between April 3rd 2015 and June 3rd 2015.

 

Summary

In segment 5 one point has 68um offset. Two files are available for corrected and non-corrected optical measurements.
