    Just make sure the tungsten is at a 45 degree angle to the beam. The X-rays will shoot straight down or up.

    Cathode rays are used to make the semiconductors that replace them. Well, not exactly, but very similar. That’s the job of implant…it bombards the silicon with either positively charged compounds or negatively charged ones.

    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 Cheers from France ;)

    To get free electrons you need a REALLY, REALLY good vacuum. A bell-jar and a simple rotary pump won't cut it. You need to get below 10E-4mb. All you'll get is fast ions from the residual air with that simple setup. Trouble is, if you manage to do it, you'll start to generate X-rays... Not good.

    Mehdi actually created x rays there, a not insignificant amount, actually. But due to the angle he probably fired them mostly backwards and into the glass and all over. To make a large amount of xrays, he would have to make the anode out of different materials, like tungsten or silver. Then, you would spin the anode on a stator to distribute the heat since that's what you mostly get. Ionizing radiation is dangerous, use a lead shield. Proper xray machines actually use an aluminum or whatever filter to get rid of the low energy photons since they add to your radiative dose of X-rays but are not high energy enough to really expose a photograph of your gutz and bones, only the crazy high energy ones are useful.

  53. Amit Bajpai

    I think you should have a bigger hole and thinner iron frame of that anode Just replace the washer with same circumference but digger hole

  54. Gerret Bertram

    You need a negativ charged cylinder to focus the elektrons into the middel of the hole in the anode.
