Hi Bob: This is very similar to a "proton precession magnetometer" that measures the total magnetic field, not in vector components. There's a lot of amateur designs for these that you could use as the bases for a MRS.
There is an article in the same publication for a tube type frequency standard that can be used to drive a line powered wall clock.
The Magnatron magnets were probably Alinco, so if you upgraded to modern magnets it might be much more stable. http://en.wikipedia.org/wiki/Proton_magnetometer http://en.wikipedia.org/wiki/NMR Have Fun, Brooke Clarke http://www.PRC68.com http://www.end2partygovernment.com/2012Issues.html http://www.prc68.com/I/DietNutrition.html Bob Stewart wrote:
First, an apology. When I changed the topic on my original post, I thought that would be OK. Apparently that's still a thread-jacking. Sorry. I'm still interested in this Magnetic Resonance Spectrometer thing, though. On page 335 of the pdf linked below by Dave, there's an experiment with an MRS using water and the magnet from a magnetron available back then. Apparently the resonant frequency of hydrogen nuclei in water is 6.131325 MHz in that magnetic field. Did anyone ever pursue this with the idea of creating a frequency standard, or was the technology just too primitive at the time? Perhaps it's a repeatability problem from the magnetic flux standpoint? I can guess that temperature changes would cause enough of a flux strength change to cause a problem, but that's just a guess.
