Dear AMMRLers,
We've got our first supercon magnet system up and running here at the CFA,
but have run into a few stupid "supplier issues" for trivial parts. I was
wondering whether anyone out there can suggest a reliable, current, supplier
for:
- helium boil-off meter, 0 - 25 or 50 cc/hr
to attach to vinyl tubing on the top of an Oxford D15000 cryostat
(I'm used to seeing ones from "Dwyer Instruments, Michigan City, IN
but can't track these folks down anymore)
- high-power 30 dB attenuator with cooling fans for hooking
RF amplifier output directly into an oscilloscope
(We can't find this in the Newark catalog - but maybe aren't looking
in the right place!)
I've never had to worry about obtaining stuff like this before - they were
just always around!
Many Thanks,
Ross Mair
