Quad location in the hutch

Hi Mikhael,

Dimitri has the fully fitted position, but very roughly:
Looking downstream, it sit behind the target on the Right.  Center is at beam height. It is rotated around the vertical (Y) axis ~40degrees. Distance to IP  is probably  around ~100mm. A very rough sketch of topview below:

2020-10-13 Geometry validation on data

  • geometry file: /reg/g/psdm/detector/alignment/epix10kaquad/2020-10-04-epix10kaquad0/2020-10-04-epix10kaquad0-geometry.txt
  • data
    • nda-meclv2518-0099-quad0-LAB6-max.txt
    • nda-meclv2518-0101-quad0-CeO2-max.txt


  • 40 degree tilt around Y is not applied in psana geometry
  • X,Y,Z camera offset relative to IP is set APPROXIMATELY in order to get "round" one of the rings on image
