Talked to Dima about the NURI magnetometer network paper. His comments:

• The device section describes a solution without a problem. Add to the introducion:
  • need for the accurate timing
  • need to correlate signals from the different sensors
  • magnetometer has to be portable

Talked to Thad about a possibility to have a synchronously pumped scalar Mx magnetometer in the fMCG project. The advantages would be:

• not having to cancel the field
• no calibration
• no 1/f electronic noise

Disadvantages:

• spin-exchange relaxation
• no vector sensitivity

Calculations for an Mx magnetometer built with a paraffin-coated 1cm3 cell show that it should be possible to get around 3 fT/sqrtHz per 1cm of the probe length.
