* [[File:2016.09.01 Group Meeting.pdf|Zack's notes]]
* Thad suggested that we should have a logarithmic amplifier (so the signal is large enough for the ADC), and a PID loop at sub-Hz frequency to get rid of the DC fields around the sensor array.
=== Fundamental noise limit estimates ===
Finished the Mathematica models of the Mx in coated cell, SERF with buffer gas and SERF with OTS coating + 30 Torr Ne magnetometers. The models estimate the best achievable performance of each magnetometer in perfect circumstances (taking into account probe and pump de-pumping). Each magnetometer has a cubic cell of 1x1x1 cm. The magnetometer ranking by sensitivity is (best to worst):
# SERF + OTS coating
# SERF + 200 Torr Ne + 30 Torr N2
# Mx
