HV voltaic arc in vacuum chamber Test

[@TheAmmoniacal]

For anyone who is curious. The two phenomena seen in this video are very different, the first phenomena with the screwdriver is an electric arc with a discharge of air molecules. The second phenomena is a "vacuum arc", caused by field electron emission at the anode and subsequent absorption at the cathode. Electrons are literally "boiled off" at the anode, and will accelerate towards the cathode by the electromagnetic field. Not so sure if I can explain the color, most likely due to iron atoms being reduced and oxidized along the path. When electrons are boiled off at the anode you'll also get gaseous iron ions (Fe+, Fe2+, Fe3+ etc), possibly also variations of Fe- and Fe* (radicals). Iron does have emission spectra at the blue and purple parts of the visible spectrum.

[@utopianfish]

First, there is an error in your comment: i think the electrons are "boiled off" at the cathode, and accelerate towards the anode.And i have a question with this video, the arc did not happen until the pressure is decreased to some value by the pump, why?

[@TheAmmoniacal]

Plasma Vacuum It would depend on whether you mean conventional current flow or real current flow. Remember that electrons are negatively charged, so they can only be attracted to a positive electrode (cathode).

[@utopianfish]

does not cathode means the negative electrode?:（en.wikipedia.org/wiki/Cathode

[@TheAmmoniacal]

Plasma Vacuum It's not that easy, because the terms cathode and anode are defined by the system itself. The cathode is defined as the electrode where conventional current leaves. Conventional current is opposite of real current. Short summary: en.wikipedia.org/wiki/Cathode#Flow_of_electrons

[@utopianfish]

yeah, i got you,Just as the instance inside and outside the battery.So what i really want to know is,why the arc did not happen until the pressure is decreased to some value by the pump?

love arcs in vacuum, the plasma is quite cool!!!

[@exonvidz9094]

it is called a cathode ray tube (CRT)

[@drspastic]

if you increase the vacuum to remove all the air, the discharge stops because there is no gas to form plasma. also notice the 2 streams generated by alternating current, negative to positive in both directions separately. don't let the streams cross: that would be bad

[@salopaindahouz]

I think it would still generate plasma from the ionize anode material

[@hikolanikola8775]

i was here for that exact question, but i found no answer :/

[@jmdavison62]

No, the discharge won't stop. The plasma you're seeing is not coming from residual gas in the imperfect vacuum.

Yesterday I was watching a documentary of a Portuguese real case of one UFO in the 70´s with a Air Force in which the pilot is currently commander,and this video explains much that is not understood in the case.Things sometimes have an explanation, we can not have the technology to do or sufficient scientific knowledge, but if they are possible?yes they are.

[@professorfidelcat]

amazing video!! I always thought sparks were assisted by presence of air particles providing the necessary conductance to these charges to jump over..it seem from your demonstration that total emptiness of vacuum actually improves its conductivity!!!! This has a lot to say about energy from dark matter or vacuum!! no wonder Tesla had several vacuum tubes in his fuelless car!! the vacuum tubes must have made energy harnessing from the environment 100 times easier!..theres a lot of unknown in vacuum waiting to be discovered!!

[@CoyoteGenius314]

Nice experiment! I read recently that the resistance of a conductor is reduced in a vacuum. It would be interesting to see how much it effects coil resistance. This may have contributed to the length of the arc.

[@MagixScience]

can some one explain to me what is happening here? I thought (doesn't matter have to be present for photons?) gases are ionized to produce photons when Electric arcs. or is it just the result of leaked/extremely low amount of air molecules ionizing? would this look similar in absolute zero pressure/stray molecules, in general?

[@diymetric3295]

wow you make a CRT

[@laharl2k]

i thought vaccum didnt conduct electricity because it has not atoms on which the electrons could travel through. Just reading about vaccum arcs, it says the plasma we see comes from the metal ions itself. Would changing the material of the tips change the colour? and what happens if you put an insulator, say a sheet of glass in between of the arc? does it go through as if nothing was there or what? Nice video!

[@TheChipmunk2008]

Laharl Krichevskoy What you say is true in complete vacuums, but these are in partial vacuum, the colour of the arc is mostly due to the gas that's present (oxygen/nitrogen). This is how Neon tubes work, they're at very low pressure, much lower than atmospheric. At 1 atmosphere, neon tubes wouldn't conduct

[@laharl2k]

[@rensvods8777]

Yeah pretty much. Electrons that aren't bound to an atom are probably zipping through the vacuum at high fractions of the speed of light as radiation until they smash into something or get snagged by the electromagnetic field of some celestial body.

[@BartManNL]

Very interesting, I really enjoyed your video. The question was already posted: I'm curious what would happen if you reach a real hard vacuum where there are little or none gas molecules left to ionize. What concerns me a bit is that there seems to be quite a big scratch on your vacuum dome? Doesn't that risk an increased chance of implosion?

[@ElectricExperimentsRobert33]

Bart Prins Yes, you're absolutely right, the bell has a few scratches, which is why I can not go a certain point in the void ;)

[@pivotmastex]

In a real vacuum there would only be x-ray bremsstrahlung emitted from the anode.

[@Spoif]

Electric Experiments Roobert33 Is there any difference in current consumption between the arc in air and the partial vacuum ?

[@ElectricExperimentsRobert33]

***** No, there is no difference, always 20mA.

[@Spoif]

Electric Experiments Roobert33 I wasn't expecting that. I thought there would have been some variance in current since it seems "easier" for the spark to jump the greater distance at lower pressure.

[@journeyonin]

can you do some tests on solar power in a vacuum, how much something charged and how long it would work for, be creative

[@lajoswinkler]

Neat video, very neat! However this is not a voltaic arc because this is alternatic current. Voltaic arcs are DC. Back in the time when Volta did arc experiments with his electrical batteries, alternating current was merely (if at all) hypothesized. Everything was done with DC.

[@ElectricExperimentsRobert33]

Lajos Winkler If it is not an electric arc, can you tell me what it's called? And those strings that you see sometimes on pylons above in AC, have a name?

[@lajoswinkler]

Electric Experiments Roobert33 It is an electrical arc, but it's not a "voltaic arc". Those two are not synonyms. All voltaic arcs are electrical arcs, but only some electrical arcs are voltaic arcs. For example in your video Test voltaic arc 310 volts DC, those really are true voltaic arcs. They even have distinctive appearance. Those violet streamers seen in ozone generators, HV pylons or Tesla coil toroids are called coronal discharge. Basically same thing as St. Elmo's fire. Ions jumping and emitting photons.

[@ElectricExperimentsRobert33]

Lajos Winkler In essence they are synonyms for arc. And this, as it should be called electric arc ?: kzbin.info/www/bejne/m6rZhKuim7eXZrc

[@lajoswinkler]

Electric Experiments Roobert33 That is an electrical one and it's quite obvious by the look and sound of it. DC arcs (voltaic arcs) are hissing and way better at melting electrodes.

Strange, looks like two arcs - one emitted by cathode and one by anode - but should be one. Is it AC or DC?

[@ElectricExperimentsRobert33]

***** Yes, actually are two arches, but then it is all one, I do not know why it is so. It is AC.

[@RinoaL]

[@Coolkeys2009]

If you leave the vacuum pump on long enough does the arc go out again?

[@ElectricExperimentsRobert33]

Coolkeys2009 The pump has a slight leak of air, which is why you have to turn on the pump.

[@Coolkeys2009]

Electric Experiments Roobert33 If you can get the vacuum high enough the arc should go out again, but I think you need a very, very good vacuum pump.

[@ElectricExperimentsRobert33]

Coolkeys2009 This pump is made in house, for what it can do is good enough. I attach my video of this pump:Interesting vacuum chamber

[@Coolkeys2009]

Electric Experiments Roobert33 The reason I'm asking is there is a video in which a KZbinr does a similar experiment with a turbo molecular pump and the arc goes out again at higher vacuums, I'm not sure if this effect is possible with a reciprocating type pump.

[@Infinion]

Coolkeys2009 The arc's not going to go out at higher vacuums. However, if the distance between the electrodes were increased to raise the breakdown voltage threshold, you might only see a glow mode discharge surrounding the electrodes themselves, and a dark mode discharge in the space between them.

Yes, vacuum sealed capacitors exist and are still used in the field today. They are called vacuum variable capacitors.

Not sure if your bucket idea is very practical to do on a large, or even a small scale for that matter.

[@douro20]

Is that an OBIT?

[@faustdownunder]

You would find that the reduction of air pressure reduces the voltage needed for arcing. In other words: thinner air has less "insulation" capability. Scientifically: the mean free path length increases when air pressure decreases.

Nice demo but I think you are wrong to call this an arc "in the absence of air." Your vacuum pump probably does not produce a very high vacuum - the residual pressure in the jar is probably a few 10s of Torr. This is a low pressure arc - at low air pressure, air is easier to ionize (lower breakdown E field). In a hard vacuum, the gap for an arc would need to be smaller than the 1 atmosphere air pressure gap, not longer.

It is the fact that the universe is actually dark, there is no light, the stars do not shine, the Sun is not bright, the Moon does not reflect its rays, everything is black, frighteningly black. Why, because light exists only if there are eyes and a brain capable of transforming electromagnetic waves into light signals, as the human brain does. Electromagnetic waves in themselves do not generate light, everything is dark in the cosmos and silent, because without an atmosphere there are no sounds. It could be said that the cosmos lights up only when the man appears who knows not only to see these lights but to interpret them.
