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

PWV 1 mm
Elevation 60 deg
Optical Eff 0.30
Telescope Temp [K] 15.0 Similar to PB2
Bath Temp [K] 0.250
Transition Temp [K] 0.427
Saturation Power 2.5*Popt Safety factor for ETF stability
Number of detectors 3794*(fcent/150 GHz)2 PB2 FOV
