=== Bison's magnetometer ===
That's the magnetometer described in G. Bison's thesis.
==== Magnetometer 1 ====
Things that can be improved:▼
http://arxiv.org/abs/physics/0406157
Achieved about 60 fT/sqrt(Hz) probe-limited sensitivity, and measured ~300 fT/sqrt(Hz) in Cs cells at 40°C in magnetic shielding in 2 μT field (7kHz). Bandwidth was ~140 Hz, minimal distance between sensors was 3cm.
# Coating instead of bare cell with buffer gas
# Use synchronous pumping instead of rf coils?
# Something to improve the bandwidth?
==== Magnetometer 2 ====
http://link.springer.com/article/10.1007/s00340-003-1120-z
Gradiometer with 4cm distance between the cells. Cells are 20x20mm buffer gas with Cs at 30°C. The gradiometer sensitivity was 2pT/sqrt(Hz) in a partially shielded room (8mm aluminium shielding).
==== Magnetometer 3 ====
Cs, D1 pump/probe, B = 5 μT (17.5 kHz), intrinsic sensitivity of 100 fT/sqrt(Hz)
(there are several more magnetometers with similar configuration and performance)
