      For example High voltage rectifier tubes are known to produce small amounts as an unwanted byproduct.
      Audio Tube Amplifiers are the most common type of Vacuum Tube Application today among very high power transmitter tubes. But there is no concern from those since they are not contained in a glass envelope but a water cooled metal jacket.
      Audio Tube Amplifiers pose no significant risk.

    Nice work!
    From the amount of Plasma I would expect a pressure of somewhere between 10 mbar and 0.1 mbar. For electronbeams that are used (either in Electron Microscopes (SEM/TEM) or for Electron Beam Epitaxy) in Lab settings we usually have vacuums around 10^-5 mbar, since in those the electrons flow much easier and are well behaved so that you can control and detect them accordingly.
    For demonstration purposes a vacuum of ~10^-3 mbar should be enough, use some Argon to show the path of the electrons.
    Also if you use a Helmholtz coil setup you can actzally adjust the path of the electrons into a circle and use that to correctly measure the charge of a single electron.

    Here's an explanation for the "clumps of gas" in the vacuum chamber. When pressure is decreased in cathode ray experiments (which you were doing by drawing the air out), the cathode ray tube goes from irregular crackling to a horizontal column that stretches from the anode to the cathode. When you decrease the pressure even more, eventually you get something called a Crooke's dark space, negative glow, Faraday dark space and striations. These striations are the "clumps of gas". There are many stages that correspond to different pressures though, so I've only just mentioned the first stage and the stage we're interested in.
    Also, I'm not an expert in this topic. I am just a high school student who came across electric currents through gases. Please do correct me if I am wrong!

    You can greatly improve the seal on your vacuum chamber by wiping a thin film of Vaseline around the lower rim of your clear container, laying a wet ring of RTV silicone on the base, and gently pressing the container into the goop. The Vaseline prevents the RTV from bonding to the glass. When the RTV cures (give it a full week), remove the container and wipe all the vaseline off both surfaces. You'll now have a custom-made airtight gasket.

    • @ArchangelUltra
      @ArchangelUltra Před 3 lety +194

      If you're curious, the source of these x-rays is the high energy electrons smashing into the anode disk and losing their energy rapidly. This rapid loss of energy is released in the form of high energy photons (the x-rays). This phenomena is called "bremsstrahlung," or braking radiation. I worked for 5 years with a Van De Graaff positive ion accelerator that needed lead shielding to protect against the braking radiation, since positive ions accelerating in high voltage (even at high vacuum) will ionize residual gas particles and release electrons that in turn accelerate backwards through the high voltage into the accelerator itself, creating x-rays.

    Hey Medhi, thanks for sharing so cool videos out there ! All are very comprehensive and funny at the same time ! (I wish I had a teacher like you back in the days before my engineering mechatronics school).
    It's been a while since you uploaded this video but as you explained it, you say that the cathode ray is producing a wind in atmosphere (due to presence of molecules). So your cathode ray is producing some thrust in atmosphere.
    So, if in (perfect) vacuum your cathode ray does not procuding thrust because of lack of molecules. But imagine that you could add some gas through the negative pole with some isolated nozzle then you could produce some thrust ! In low gravity and vacuum that makes a tiny ion thruster isn't it ?
    Well, congratulations Medhi, you have made half a space ion thruster !
    Anyway, your videos helped me a lot in my profession in some fields and I'm always pleased when you upload new contents ! :D

(Rad tech). MEV is higher voltage This guys needs to stop playing with higher voltages and using cathodes and anodes. This is exactly how you make X-rays. Use high voltage send that to the cathode, send the electrons to the anode, and with a vacuum, there is still a possibility of leakage radiation. There’s reasons why a lot of scientists don’t play with this anymore. X rays are very dangerous if you’re not careful enough. Seriously kids, don’t do this stuff at home, not worth getting cancer over this

      I wouldn't use the term "Strength", also I would add: divided by distance².
      For a X-ray sources mA·s and KV are commenly used for driving the tube. mA·s = current * time and KV is obviously voltage. mA·s is the main way of controlling the amount of X-ray photons produced by a tube while the voltage increases the photon energy, measured in KeV (electronVolt). The voltage actually also has a huge effect on the amount of photons so mA·s has to be lowered to compensate. However, X-rays with higher photon energy are actually less absorbed in a body compared to X-rays with lower photon energy. If someone wants to see soft tissue better compared to for example bone it can be useful to lower the voltage a bit. This is a way to control the contrast in X-ray imagery. You can also take images with MeV equipment used for radiation therapy, this however created images with extremely low contrast compared to normal X-ray equipment because a lot of the X-rays will simply pass through the body without interacting at all.
      So "Strength" doesn't really say much in x-ray physics!
      Obviously the physics and biological effects behind X-rays are quite a bit more complicated. But my knowledge is incomplete and a bit rusty so to say.

Had an old civil defense radiation detection kit and started noticing the radiation dosimeter were constantly pegged even after being reset. Radon? no check for that regularly. Ultimately it turns out that high voltage Spark x-rays ,tungsten and beryllium are not things to keep in close proximity to your marxx generator.

    9:13 I believe this is the effect also seen in the Franck-Hertz-experiment. The electrons get accelerated and gain speed (kinetic energy). Once this energy is high enough the electrons can give that energy to one of the remaining air molecules exciting it in the process and making a glow. The electrons are now slower since they gave away the energy and they get accelerated again until they can give their energy to the next air molecule and so on and so on.

    re - 9:25
    This is my guess as to what the _Corona-Diamonds_ are:
    They're visual representations of the ionisation energy of air. The farther away from the cathode they are, the lower energy they receive, so they're in a lower ionisation state. The closer we get to the anode, the more energy they receive, so they're in a higher ionisation state. Hence the first diamond represents the first ionisation energy of air, the second diamond represents the second ionisation energy, etc...
    Again, that's a GUESS, since I'm an organic chemist and not an electrochemist. If anyone knows for sure what's going on, or even if they just know that I'm wrong, I'd be very interested in finding out.
    NB: Even in the absolute BEST vacuums humans are able to construct, there's still a density of about a trillion molecules of gas per cubic centimetre. I doubt that this is anywhere near such a vacuum, so the gas density is quite likely to be orders of magnitude greater.
