- 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.
- orientation of quad labels should be human readable (from left to right) in hatch hutch position;
...
- 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).
