Detector name labels
Add label with unique detector name on each camera body
- agreed on unique detector names: 2M.0, 2M.1, 2M.2, ...
- if expected number of detectors more than 10 it is better to use 2M.00, 2M.01, 2M.02, ... (better for files sorting in catalogs).
Why it is important? We need to distinguish detectors in optical metrology and geometry constant files. It does not matter for intensity correction, where detector will be identified by the panels Id from data.
Optical metrology
Use the same measurement pattern for all epix10ka2m detectors
- orientation of all cameras in optical metrology should be always the same
- order of measured points should be always the same
Why? We have to unambiguously map panels in optical metrology and in data from DAQ. Different detector orientation or different order of measurement need in special treatment in the processing script, which is error-prone and always needs in verification.
Camera orientation in optical metrology
Preferred optical metrology pattern from 2018-11-18:
- orientation of camera should be consistent with its beam-view in hatch, Q0 in top left corner.
- orientation of quad labels should be human readable (from left to right) in hatch position
- on current photo labels need to be rotated upside-down (right photo shows how embarrassing labels look in the hatch)
- add labels for vector of gravity or x-y for optical metrology in order to exclude wrong orientation
- orientation of quad labels should be human readable (from left to right) in hatch position
Measurement order
- measurement order of points per quad should be kept in Chris Kenney's style as shown on photo
- microscope origin location does not matter
- metrology data is saved in xlsx (or text) format
- units - micrometers, without decimal dot
- example of data:
Label on connectors and cables
- All labels on detector connectors and cables should show THE ONLY way to connect camera.
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 hatch (for now they are upside-down)
- Use the same detector orientation in optical metrology, Q0 is in upper left corner in microscope x-y. Origin does not matter.
- Connect camera connectors to properly labeled cables.
