Notes

Questions:

  • What plans for instrument systematics modeling on the decadal timescale and beyond? What instrument parameters values should we use, guided by simulations & experience?
    • Complementary performance-based and ab initio forecasting
    • Write down specs for eg. bandwidth, NET, etc, justified by demonstrated performance
    • Need single reference document for all of these (wiki page? google sheet?)
      • Organize by subsections of CDR reference design chapter
      • Incorporate achieved values from S3 experiments
    • Cascade diagram progressively decomposing each element
    • For many boxes there are uncontroversial numbers that can be used as the starting point
    • On which parameters do we need to do better than S3 to achieve our goals?
    • CDT framework provides maxima for eg. additive contamination
      • see CDT report appendix A, wiki links & forecasting paper in progress
    • Track propagation of systematic from source to power spectra to identify scaling with eg. number of detectors
    • What's going to be hard?
      • Beams, beams, beams & beams
