Varian 860 cold cathode controller
I have a dead varian 860 cold cathode controller for a vacuum gauge. It got shorted out inside and I’m not sure I can fix it (replacing one burned out resistor didn’t suffice) and I’m not sure of my ability to track down and fix anything else that blew out also.
Anybody have a good one they’d like to sell? The 860A would probably work, too.

Pretty sure he was a member here at one time....? All my kit came of eBay even if at time postage was more than the item price!?
So guys keep your eyes open you’d be surprised where gear can show up.

Check this out!
FYI this guy is pretty sharp. You get get along with a chamber made from a propane cylinder. He also has built a bigger system using carbon steel plate and a welder. Try to get creative. Diffusion pumps I think are on ebay a fair amount.

I used an old ammonia tank from an industrial refrigeration
system, 1/2" thick walls 18" in diameter. Was a bear to cut wet
too considering it was 6' long!
Got to love a good scrap yard.

nope...we have Trademe.co.nz but its way over priced for
second hand stuff and very rarely anything interesting
turns up...when it does they want full price someimes far
more than if it were new!!!
i do buy ebay usa though and europe...i recently got a
really cool Depostion controller, it measures and monitors
the thickness of depostion coatings for 200 bucks! really
neat kit.
A VAC chamber form a pressure vessel?? i thought that
wouldnt work and they are designed thin but compound to
resist burst pressure rather than vacuume.. i cut one open
myself and it was 2.5mm thick not enough for a vacumm.
maybe 4mm mild steel right?

Hi Drew,
Yes it is, I'm actually in a dual degree program, so get my
medical doctorate and a bachelors in surgery too... Long road
indeed!
How are things in sunny Florida these days?
Cheers, Thomas

I think im going to move to PA!!! But alas its a long way from New Zealand.
I myself am a lurker, and not messaged within this group before, im collecting pieces to build myself a telescope sputtering chamber, so i joined to get tips and to learn from some rather experienced individuals.
Im almost there, all i need is a diffusion pump and either a 14" bell jar or a tig welded stainless chamber, but getting hold of pressure vessel heads here in NZ is nigh impossible as with almost everything i am interested in...so its custom spun heads or a bell jar, both qiute expensive.
I am so enviouse of the surplus shops and brick'a'brack junk shops you have in the USA, i tottaly would jump in my truck and travel interstate to pick up an old chamber or bell jar, the adventure of driving tot new places and to pick up some "science gold" at the end of that rainbow is intoxicating. nerd-vana!!

I'm an electronics guy working as a consultant in the embedded systems world. I have a background in instrumentation, some working knowledge of lasers and physics stuff, and a strong interest in vacuum systems. I have some vacuum hardware, and a lot of lab space (which seems to be what most people lack, which is why I mentioned "stuck in a small house" above) in a pair of commercial buildings that I own. I'm based just outside of Pittsburgh. Is anyone here nearby and up for hacking? I've got some hardware (and am willing to amass more), space, power, and interest...just need someone to work with who will take the lead on getting some vacuum goodness going. Oh, and there's also that nice electron microscope over on the other side of my lab. I had it running great many years ago, but it has been open to air since then. Gotta get that running.

It was built by the original developer of the Yahoo Groups system, and is very good; it has some nice migration tools that can be used to move group files, even archives I think. It's good stuff.

Well, let’s generate some traffic!
?
About 25 years ago I worked at a small thin
film R&D
outfit in Ventura CA. It was the most fun job I’ve had. Part of it
was
maintaining the sputtering system that was central to the whole
operation. It
had a 5HP mechanical roughing pump followed by a small turbo.
Turbo was
connected to the load lock chamber. The sputtering chamber itself
was pumped by
a cryo. It was a two target Gartek sputtering system. A shuttle
system,
magnetically coupled to an external drive, moved a pallet holding
the wafer to
be coated from the load lock to the first position - a
water-cooled table that
raised up to hold the pallet. Bellows allowed the motion in the
vacuum. Once
the cryo took the chamber down to 10^-6 Torr (ion & pirani
gauges) the
chamber was flooded with a small amount of Argon. A magnetron
target above the
wafer was then energized with either 13.56 MHz RF if it was a
dielectric target
or DC HV for conductive target. The resulting plasma sputtered the
atoms from
the target to the wafer. When that was done the wafer on the
pallet could be
moved farther into the system to the next table and target for the
next
material coating. We sputtered Gold, Palladium, Titanium,
Titanium-Tungsten,
Copper, and some dielectrics that I don’t recall. I wrote the
software that ran
the system in Forth (the boss liked Forth) rebuilt each pump,
designed the load
lock door and target magnets, and so on. Thus began my love of
vacuum science.
Now I have a small diffusion pumped system in my home shop, just
for fun.
?
The gurgle of a roughing pump, the whine of an
accelerating
turbo, the throbbing of a cryo cold head drive. Music to my ears.

It should definitely be moved, probably to like the rest of
the Yahoo! groups, before it disappears completely.
