Atomic Magnetometer

Atomic Magnetometer. Continuous HighSensitivity and HighBandwidth Atomic Magnetometer Abstract Here we demonstrate an atomic magnetometer that has a bandwidth of more than 100 kHz and a sensitivity of 180fT/√Hz at a Fourier frequency of 8 Hz and 07nT/√Hz at 100 kHz.

PDF fileA comparison of the electromagnetic survey and the magnetometer survey shows that the conductors outlined were roughly coincident with magnetic lows thus indicating that the conductors were due to long areal faults There were a few conductors not due to conductive overburden or swamp these occur as follows L7 at 12 + 00′ North of baseline L10 at 4 f 00′.

Atomic magnetometers work by detecting how the energy levels of atoms are modified by an external magnetic field This is the famous Zeeman effect – a quantum effect whereby the magnetic spin states in an atom split in the presence of an external magnetic field.

SERF Atomic Magnetometer–Recent Advances and Applications

An atomic magnetometer of superior sensitivity is the spinexchangerelaxationfree (SERF) magnetometer It is noted that it requires zero ambient magnetic field Its principle of operation is described below and in Figure 2 A droplet of alkali metal eg rubidium in a glass chamber is heated to produce a vapor (gaseous phase).
