[volt-nuts] Low-cost Josephson Junction Array

Well, I already have a 3458A, a 34420A, a GPSDO (with 10Mhz output), and so
all I need is something that produces a fixed 10V (and 1V would be OK too).
I was thinking of something like the "Compact Josephson Junction Array"
[CJJA] that is used for inter-comparisons, etc. This unit has an SIS
array, and is very "finicky" to get working-- so something based on a SINIS
array (highly damped) or something similar that can be used without having
It is already understood that NIST has the best solution for this if you
want the "Cadillac" version, (and have virtually unlimited funds)-- but I
don't have unlimited funds, and I don't need a programmable output, and I
don't need to generate AC waveform, and I don't need or want all of the
complexity. $400K is *WAY* out of my budget. I was looking more for
something on the surplus market-- or some "cast away" JJA that someone is
getting ready to throw into the dumpster-- something that nobody wants
anymore that I can get working on a _very_limited_ budget... That's why I
mentioned the CJJA, because that has the RF source and everything built-in
(well, except for the programmable current source, but I can build those
all day long in my sleep).
