Coaxial microwave plasma with filaments

  • 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?

    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?...

    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?

    • @bensonburner3852
      @bensonburner3852 3 роки тому +1

      Hmm not sure what you meant but I think you cannot create new net charge because that would break charge conservation.

  • @bringer-of-change

    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?

    • @TheExplosiveGuy

      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.

    When are we gonna see this in prisons?

    • @kezadrone
      @kezadrone 8 років тому +1

      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.
