[neonixie-l] Home made helium leak detector:)

[Alek onet]

Hi everybody,

 I hadn't helium leak detector, because of high cost. So far I detected 
"holes" using primitive methods (by acetone, alcohol) but it wasn't easy.
 My friend gave me old russian 180 angle mass spectrometer for helium 
leak detector. Inside is simple ion source and faraday's cap. Old vacuum 
tube preamplifier was bad, that's why I build my own.
Power supplier for ion source and detecting circuit is my own too. 
Yesterday I throw out original magnets (it was very heavy -ca 12kg) and 
changed to neodymium magnets.


This detector could be connected to high vacuum system, as it shown here:

Hi Dalibor,

Are you calculated cost of manufacture of tubes?

Hi Michel,

You are right, I am also eager to it glow. As soon as the shed is 
built, I will move all the stuff there and start with it.


It should be a replica or copy of z568m, so the size of the numbers is 
5cm. I actually dont have any z568m, so other dimensions are measured 
from z566m and scaled. Isnt there anyone who has faulty z568m to cut 
it open? ;-)


With the gold plated stainless steel - You actually jumped ahead, I 
have this idea with the anode electrode (grid), that will be possible. 
The numbers must be made of steel as all other metals sputters a lot 
more and the life of the tube would be short. It would be possible to 
make it also from brass, but the pumping time would be many times 
longer than with steel because it would be done with low temperature - 
I guess 100C instead of 450C. Once the tube is filled with gas, the 
brass should not relieve zinc as the vapour pressure of zinc is small 
enough. Zinc starts to cover the glass envelope at pressure of 10-6 
torr and temperature of 200C, conditions during the bakeout process.


bye!


2013/6/26 Michel mailto:mic...@xiac.com>>

Beautiful work Dalibor!
What is the size of it? Looks like IN-18 size?
Can't wait to see them light up, you too I guess :-)

The brass really looks stunning and stands out between any other
nixie tube, it's a pity that you can't make them like that. Would
9k gold work, or gold plated stainless steel?

Re: [neonixie-l] Re: Nixie tube making: first glow lamp up and running

[Alek onet]

Dear Dalibor,

Photolitography devices are original pieces. It was used for polish 
industrial nixies, but rather for laboratory scale. When prototypes were 
good, manufacturing go to Dolam, Wroclaw. I suppose that there were 
similiar devices, but bigger.
I used hydrochloric acid with perhydrol H2O2 and pure water. I'm going 
to try with molybdenum foil and cupric foil for another parts, not for 
nixies.


 I'm very tired now. That's why I must go to sleep. I promise you 
answer good as quick as possible.

it is not so easy, the total surface of each digit should
be constant to achieve constant current and constant
brightness of each digit (else You will have to struggle
with resistors on cathodes..). Bigger number = higher
current..

While this is true, it isn't an absolute.  Existing nixies
have different currents for different digits (particularlay
"1").  Since they're more-or-less constant
voltage devices, the anode resistor tends to even out the
different current draws.  Running nixies from higher voltages
with larger anode resistors
helps with this (at the cost of efficiency).  Some designs
actually use current regulation instead of anode resistors,
and these will tend to overdrive
the smaller digits slightly.

That said, it would be simple enough to write code to adjust
the digit stroke thicknesses to achieve matching total areas.
 Note that in some nixies,
the "1" digit is made with a double stroke to help with this.

And I also like the retro look of original digits ;-)

That is a perfectly valid reason.  If I were going to clone a
nixie, I'd choose the CD-66 with its particularly nice digit
shapes.

However, if I'm making my own nixies, I'd be interested in
making them visibly distinct from existing ones.  If I want a
CD-66, I
can just go buy one (unless I want a CD-66 with 30mm digits).
 If I want a nixie with Böcklin or Klingon digits, I'll have
to make
my own.

There's also a mechanical consideration - thicker digits will
be more rigid and stable, and should survive longer.  However,
this thickness can be in material thickness or stroke width.

Once I have working tube (as close as possible to
original) I can play and change things inside..

Absolutely.  Coming up with digit shapes is likely not the
most difficult problem in making nixies.

Have You made something working with mentioned digit graphics?

Not as of yet.  My original plan was to photoetch them, but I
just heard from someone who's making custom variable
capacitor plates, and has access to a water jet cutter.

I've been pricing the little ceramic rings used as insulating
digit separators, and they're expensive, so now I'm thinking
of glass and mica as alternatives.

Next, I will experiment with the aluminum oxide
insulator. Sadly, it is quite brittle, so if you shake
the tube too hard it will break loose. But I could use
this insulator to prevent parts of wires to glow.

But I doubt that air is going to get any brighter, Argon
would probably yield much better results.

lead-in-wires with tungsten middle sealing part. I tested them
on helium leak detector and some of them are ok! :-) So now I
need the lathe to make the envelopes and seal it..

I also did simple experiment with photo-etching of numbers
from thin stainless steel sheet. It works, but the etching
proces will have to be made more even and much much faster to
prevent under-etching..

I also had to build new transformer spot welder, the capacitor
discharge welder waswaste of time :-( the new one can be
adjusted, tungsten-steel welds are now really easy :-)

Thanks Michel, I am planning to do all kinds of glow lamps
before I get a real torch, a real colon display would be nice.

Next, I will experiment with the aluminum oxide insulator.
Sadly, it is quite brittle, so if you shake the tube too
hard it will break loose. But I could use this insulator
to prevent parts of wires to glow.

But I doubt that air is going to get any brighter, Argon
would probably yield much better results.

Jens


Nice work Jens!

Would be a good combination, nixie tube clock with
glow lamp colons or
something like that. It doesn't seem as bright as neon
but that is
probably because it is a prototype.

Hi folks,

finally I got my first glow lamp working. It is
the third try, therefore
I call it "GL-LS-3", short for glow lamp lab
sample 3. See two pictures
here:


http://www.jb-electronics.de/tmp/gl-ls-3_1.jpghttp://www.jb-electronics.de/tmp/gl-ls-3_2.jpg

It consists of 9mm soda lime tubing and Dumet
wire. The gas filling is
normal air at 9mbar. It ignites nicely at roughly
550V DC.

I used a simple propane torch for the glass work.
Will switch to a
hand-held oxygen-propane torch in a few months
though (when I have
enough time and money).

I will get my needle valve in two weeks or so,
then I will be able to do
something with neon. Believe it or not: over two
months lead time for a
silly needle valve... Anyway, I hope I will have
the tube making content
prepared for my website by then. It is piling up,
but there is still
much to do.

Re: [neonixie-l] Re: nixie makers: getters

[Alek onet]

I have mercury dispenser, used in fluorescent lamp. I think that it's 
safety. I have also a lot of small Ti-Hg "drugs" for plasma displays, 
but I'm not able to use it. I don't know how to use it. I used liquid 
mercury, but I hate this method:/.

I can't to tell that Ron is right.
 If you want low voltage supply (below 180V) and long life for nixie, 
you should have the atmospere Ar, Ne and Hg.
I have old polish documets about AC and DC-PDP (plasma displays) and 
there is a lot of informations about good mixtures.


I haven't glass lathe so far, thats why I can't prepare so beautifull 
glass wafers as Ron:(

Hi,

but where do you get the mercury dispenser? Do you have a source? I am 
just curious because I searched for it some months ago and did not 
find any.


But Ron is probably right: Many Nixie tubes neither have getters nor 
mercury in there, so the bakeout really is the crucial part.


Jens

Mercury + stainless steel cathode are the best combination for the 
longest lifetime of the tube. Another possibility is to use 
molybdenum cathode, but it is not easy to obtain (0.1mm shim), I dont 
know how to etch it, it is quite brittle to work with and difficult 
to spotweld to lead-in-wires. I will fill mercury by mercury 
dispenser - metal compound, activated by heating, this procedure 
relieve the mercury.. Similar to flashing the getters,


Dalibor

2012/6/26 glasslinger mailto:rons...@att.net>>

Good reason for not using mercury in your tubes! Pick a low
sputter cathode metal so it isn't necessary. Also, getters are
not really necessary in tubes operating at nixie tube pressures.
Just do a good bakeout and you will be fine.

There is so much glasswork to figure out for me,

Hi Dylan,

flashed getters are not used in nixies (I havent
seen it at least), just some VFD tube use flashed
getters. Flashed getters leave a coating on a glass
envelope of the tube - we don't want that. I think
that kind of getter needs only initial activation
by heat which could be done by induction heating as
well as in the case of flashed getters. Look to
IN-14 nixie, there is exactly the same pellet.

The only matter to solve will be attaching the
pellet to a wire, but I think that will be possible
to do by spot welding - inspired by IN-14.

Thanks,

Hey Dalibor and others-
   I don't feel that these are the right
getters for nixie tubes.
   The literature lists them as thermally
active- they only absorb if you put them
somewhere hot.
   Many styles of getters are made this way;
most tubes do run quite hot, beacuse of the
filaments..

   There isn't anywhere in a nixie tube that is
constantly 100C-200C. (That's part of the magic
of nixies, of course)

   You really want some flashed barium getters;
they absorb gasses at any temperature.
