  • orientation of camera should be consistent with its beam-view in hatchhutch, quad Q0 in the top left corner.
    • orientation of quad labels should be human readable (from left to right) in hatch hutch position;
      on current photo labels need to be rotated upside-down. Right photo shows how embarrassing labels look in the hatchhutch.
    • add labels for vector of gravity or x-y for optical metrology in order to exclude wrong orientation
    • microscope origin should stay the same during the measurements. 
      Origin location does not matter,  but it can optionally be labeled somewhere for uniformity of metrology data. 

...

  • All labels on detector connectors and cables should show THE ONLY WAY to connect camera in hutch.

Detector name in DAQ

  • Latest incident revealed by Philip on 2020-07-16 - "We've been mostly using the 2M.1 camera but the daq calls it 2M.0."
  • Detector name like DetLab.0:Epix10ka2M.0 is used to access data in xtc file.  
  • it should be consistent with calibration constants, like
    /reg/d/psdm/det/detdaq18/calib/Epix10ka2M::CalibV1/DetLab.0:Epix10ka2M.0/pedestals/<run-range>.data
  • To prevent mess with names it would be nice to use the same detector name on camera in hatchbody (2M.0) and in DAQ (DetLab.0:Epix10ka2M.0).

Summary

  • Engrave detector name on camera body.
  • Add labels for unambiguous detector orientation:
    • vector of gravity,
    • x-y (and optional origin) for optical metrology,
    • all labels should be left-to-right readable in the hatch hutch (now for 2M.0 they are upside-down).
  • Use the same detector orientation in optical metrology, Q0 is in upper left corner in the hatch and hutch and in microscope x-y Cartesian frame. 
    • Origin location does not matter, but it is better to label for uniformity of constants.
  • Use the same order of measuring points per quad, as numerated on photo.
  • Plug-in properly labeled cables to the properly labeled camera connectors.
  • Use the same detector name on camera body (2M.0) and in DAQ (DetLab.0:Epix10ka2M.0).
