Really?? Holy cow...how do they deal with dielectric leakage
problems? Over time, that charge should decay to pretty much
nothing...and not a whole lot of time, either.
That's a really interesting use of a SQUID.
A physics-oriented friend of mine keeps suggesting that I build one,
because I have an interest in proton-precession magnetometry and
gradiometry. Someday I hope to have that much free time.
