Introduction

This page is dedicated to comparing the relative sensitivities of the various proposed band configurations for CMB-S4.

Assumptions

Below are input assumptions that are common to all calculations.

Parameter Value Comment
Band Shape Top Hat
PWV 1 mm
Elevation 60 deg
Optical Eff 0.30
Telescope Temp [K] 15.0 Similar to PB2
Bath Temp [K] 0.100, 0.250 Considering both a Dil fridge or ADR, and a He3 fridge
Transition Temp [K] 0.171, 0.427 1.71*Tbath
Saturation Power 2.5*Popt Safety factor for ETF stability
Number of detectors 3794*(fcent/150 GHz)2 PB2 FOV

To simulate the sky temperature, we use the [[][AM code]] using the [[1][example configuration files]] for the Chajnantor plateau and the South Pole.
