Coaxial microwave plasma with filaments
Вставка
- Опубліковано 9 лют 2012
- Coaxial microwave discharge at various low gas pressures in argon. A central copper antenna radiates 2.45 GHz microwaves. The antenna is encapsuled in a quartz tube with atmospheric pressure in the inside. On the outside of the tube, in the low pressure, the microwave fields ignite the plasma, which in turn renders the outer shape of the quartz tube. The plasma is basically the outer conductor of a coaxial cable. Taken at the TU/Eindhoven, www.tue.nl/?id=18805
The plasma is in low pressure, while the antenna is in placed in a tube with atm pressure...otherwise the plasma would ignite there as well.
"mbar" is a unit of pression which state for millibar, so 1 thousandth of 1 bar; the latter being equivalent to atmospheric pressure conditions
Beautiful
As the EM-field strength from a magnetron is rather small, it will be always easier to create a plasma at 1bar by a HV source, so kind of corona discharge.
Hello! that it takes place at a pressure of 5?
That is the most amazing color purple...
I am trying to create hydrogen plasma at 1 bar in a small reaction chamber, and was wondering the best way of going about it, from using a HV, high Freq tesla coil at 4 Mhz, to using a magnetron, or a combination of both.. Thanks the reply...
Fully vacuum means no particles at all, first, that is impossible, but second, if no atoms: nothing can be ionized, no charges, just nothing.
Microwaves as all em-waves propagate in empty space, but there is no materia to interact with.
what conditions was atmospheric, inside the tube?...
what is an mbar? can you unabreviate?
so is reflective resonant, interesting! in phase or or out?
ahh this is the answer I REALLY seek. Is it possible to make a plasma that once charged enough be able to produce it's own charge?
Hmm not sure what you meant but I think you cannot create new net charge because that would break charge conservation.
A have so many questions. But I'll start with one. Can plasma be charged enough, or made to be able to contain a separate charge like a battery, to be able to remove it from the power source?
The short answer: no. Plasma is defined by its ionization energy, it's doesn't store or collect energy, it simply _is_ energy. Fusion power generation is an attempt to collect energy _from_ plasma, that's about as close to energy storage in plasma as you will get.
at 3.5 mbar it gjenerate x-ray plasma
Point of this being.....................?
Is this a method of doing or effecting something?
What would happen in a vacuum?
MOAR MBARS!!!
Light saber. That would be a cool experiment
Thanks...
I would thumbs up his vid a thousand times if I could. At 15 mbar, does it not look exactly like our skies do now and days?
Is this a distortion field in the frequency?
When are we gonna see this in prisons?
Probably like most technology, it's there but cost prohibitive to use on a large industrial scale. If we were truly advanced, all this stuff would cost near nothing. Also, you'd need to have a set of traditional bars between the beams, prisoners would only use them to kill themselves or harm others including guards or even start fires, you won't see them used for such a thing.
@@kezadrone except that these plasma work at such lowpressures that would kill inmates. in ambient pressures, you'll get an electrical arc. i propose a giant tesla coil. but who will pay the electricity bill ? taxpayers. so no. steel bars are still more efficient.
Hi, Can you tell me how did you make the laser?
Now make a lightsaber.
im not educated enough to understand what i am seeing :) wikipedia here we come.
cool though..........
crazy to think what people are doing inside their garages hahaha

Well, was part of my PhD, so it was a "government garage" :)
+streamingplasmas
This would make for a very cool looking nightlight ... I just don't know how cool the RF radiation would be for me XDDD
You can make banana jelly
E=mc2
Or does it? Moooaaahaaahaahaaa.
Wow something cool, but no fucking clue!
f
me neither^^
+zzzlt top secret =D
Look im smart. but not smart enough for context.
