  • This is a very poor vacuum -- unfortunately, the tech for making a really good vacuum is frustratingly expensive and specialized. You can get much better results, and a much better distinction between a cold and hot cathode, with a high vacuum. (you need a much higher vacuum to get truly ballistic flow of electrons, and at that point no current will flow unless the cathode is hot.)

  • 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.

  • 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.

  • If invert the polarities of the electrodes, you will create an "Anode Ray" and a purple glow will emerge from the hole in the cathode (Originally the anode). Great video as always!

    ElectroManElectroMan26 ימים לפני
    • Exactly. Since positively charged particles (Protons) are much larger than electrons, they 'Fly' through the hole in the anode and collide with particles of nitrogen still left in the vaccumm chamber. As they are forced to stop through these collisions, the kinetic energy they had is released as light and heat. Due to their greater mass relative to electrons, the energy that they had stored through motion is much greater than that of an electron moving at the same speed thus a much brighter 'Glow' is achived and seen exiting from the hole in the anode.

    Sushovan PaulSushovan Paul27 ימים לפני
  • I’ve seen some other videos on cathode rays, and they typically have a tube or ring of glass between the cathode and the anode so the electrons don’t just go directly to the anode
