Charge

This session combines two originally proposed sessions:

  1. Shielding / sidelobes / optical performance
    • Synthesize thinking on optical simulations and sidelobes from ST and LT and ensure all issues are covered, and that people are communicating appropriately.
    • Connect the sidelobe performance requirements (from measurements and observing simulations) to instrument requirements on shielding and cryogenic absorbers
    • Evaluate performance of existing shielding plans in both ST and LT
    • Evaluate groundshield requirements separately for south pole (flat) and Chile (~15 degree mountains nearby)
  2. Atmosphere & Ground-Pickup modeling for simulations
    • Define the simulation plan for connecting timestream performance requirements like low-frequency performance and modulator speed to map-space and ell-space noise requirements
    • Define a simulation plan for connecting ground temperature variation and ground shielding plan to map-space and ell-space noise requirements


Agenda

  1. Shielding / sidelobes / optical performance
    • Patricio Gallardo pdf and Johanna Nagy File:CWRU ground pickup.pdf: LAT Sidelobe calculations and addressing whether a LAT ground screen is needed
    • Kirit Karkare : Science forecasts including LAT/SAT sidelobes and non-ideal instrument performance
    • SAT sidelobe studies
    • Discussion of next steps for sidelobe and optical performance modeling and integration into simulations
  2. Atmosphere & Ground-Pickup modeling for simulations
    • Sara M. Simon : Scan Synchronous Signal slides
    • Clem Pryke : Connecting raw detector sensitivity and optimized scanning strategies with final map depth wiki post
    • Reijo Keskitalo : Atmospheric signal
    • All : discussion on the ground and atmosphere simulation plan
      • Define "timestream performance requirements". How do they map onto pixel and multipole noise requirements?
      • How does one go from ground temperature variation and ground shielding plan to pixel and multipole noise requirements?
