This session combines two originally proposed sessions:
- 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)
- 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

- Tyler St. Germaine: SAT sidelobes slides
- Discussion of next steps for sidelobe and optical performance modeling and integration into simulations
