Possible Simplifying Requirements

  • don't change geometry
  • serial numbers for all detectors
  • understand detector non-linearities before experiments
  • if you do change geometry have a way to get new geometry info in a standard way
  • stable beam-center (um, jets 50um). standard way to get beam center
  • stable jets
  • make jets/beam comparable unless you needstable need stable to a pixel-size
  • stable experimental setup
  • don't switch between sparse/dense photon cases for spectrometer, and/or understand in advance
  • measure detector tilts
  • avoid double-beam-focus seen in SPI
  • smaller pixels would mean photons don't occupy single-pixels, and we would get fooled less by hot-pixels
  • gravity sensors on cameras
  • more fiducial markings for geometry
  • better calibrations for motor to positions
  • hardware protection for cameras to avoid changes due to damage (camera replacement, bad-pixels)
  • for xpp ring-center finding:
    • make t0 finding fast (need to have pump-probe time set to see radially-symmetric physics signal: to see physics signal need to look at angular integration, which requires a rough center)
    • need to put a well-known sample in exactly in the right spot
    • or use the jet solvent itself
