====== 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, applied to 30K Primary
  * Computed bolometer Gs & taus
  * Ploted NEI vs frequency
  * Computed NEP white-noise plateau
  * Compared to B2/Keck Data
  * 1/f 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 (?)  Also repeat analysis for more realistic loads from window and filters, whose loading will not be negligable.
  * 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.

Slide decks for public discussion:
  * {{::Noise_for_CMB_Probe_v2.pdf|Imager Telecon 20170919, TDM noise Study}}
  * {{::flicker_noise_CMB_probe.pdf|Imager Telecon 20170919, 1/f noise Study}}
Note: slides are a funny way to add content to a wiki, but since they lend themselves well to JPL's document release protocol, I will put most technical content in that form.
