Hi folks,
Had a bit of an accident in the lab this week.
As we all know liquid N2 and fingers just don't mix.
So typing is a bit of a pain. However the YCBO test
went pretty well I think. Got some good numbers and
I'll investigate more after the blisters pop. Just
a note. In the future use Indium seals for everything.
Don't believe the manufacturers hype when your safety
or health is on the line. Could be bad. And a bit
pricey when your LN2 goes bye bye before you can shut
it off. Shield is up to 3.25% or so but again I need
to crunch the numbers. The Burr-Brown isolation amps
are acting wonky. I need to go with something hermetic
since the thin film substrates seem to be suseptable
to the wide temp variations from being so close to the
detectors. I'm looking for a new supply of Indium for
the primary seals so for now the gravity shield tests
are going to be on hold. On the positive side though
I did pick up an eight channel NO2 cooled IR detector
for almost nothing (retail 35,000$) I've fixed the
cracked window so the next tests will provide more
information on the superconductors internal heating
from induction in the subtrate. Check with the gravity
research site for more information. Well, just a short
note. By the way I haven't received any requests lately
for components. The local club members are soaking up
the parts but they're located on thier own private
site so they don't come through here. Drop a line if
anything in the database is of use. The prices listed
are only for tax purposes. If you want to support the
club by buying that's great. But if you're in need and
don't have the funds.... Well, that what we're here for.
