General thoughts

General thoughts/questions

• Try mixed buffer gas cells, with Ne or He instead of most of N2, only have ~10-30 Torr of N2 for quenching
• Optical fibers to carry the light back from the cell, to not deal with the photodiodes being close to the sensors
• Have a gradiometer within the same buffer gas cell
• Measure somehow the coating shift for m≠0
• Try Mx magnetometer in cells with a little bit of quenching gas, will the performance at T≈40°C be any better?

Cell making patent holders

What are the other cell sources? Vitaly Shutov gave me a list of all cell-related patents, because maybe the patent holders make and sell them File:Cell patents.zip (Page 2 also contains atomic-clock-related patents). Patent holders:
