Noise Modeling for CMB Probe

Roger O'Brient

This page summarizes work on TDM noise models. We should probably create one page for noise models of both TDM and FDM flavors, for one-stop-shopping. We could edit this page to add in FDM computations as well.

What's done so far:

  • Loading model constructed
  • Compute bolometer Gs & taus
  • Plot NEI vs frequency
  • Compute NEP white-noise plateau
  • Compare to B2/Keck Data
  • Flicker noise study (emperical results, pulled from the literature)

To do:

  • adjust the sampling frequency and nyquist inductors to study how aliased noise changes
  • Repeat analysis for 4K primary (?) Repeat analysis for more realistic loads from window and filters.
  • Generalize to higher MUX factors
  • Make plots of noise vs stage temp and optics for Chris' cryo design.
  • Form focal plane mass estimates for Chris' cryo design.
