Are X-Rays Produced From Plasma Compression?

- This is my attempt in capturing if x-rays are produced from my theta pinch plasma compression videos. I had to rebuild the circuit and retest everything but this time, I can control everything remotely. For that I used a raspberry pi with a relay board and I controlled everything through SSH.
If the intensifying screen won't work out, I would imagine a Scintillation crystal tube and the Pi-camera behind it to detect the energy from the scintillate (i.e. re-emit the absorbed energy in the form of light). There might be an issue with visible light getting through, but with a Beryllium screen in front, it is possible to block visible photons.
As a metal, beryllium is transparent or translucent to most wavelengths of X-rays and gamma rays, making it useful for the output windows of X-ray tubes and other such apparatus - so it would also be useful as an input window.
You could also test the sensitivity using a natural ionizing emitter, say using Uranium glass - as Uranium 238 is a beta emitter.
Looking forward to the next video :ø)
Edit: If you 'just' want to confirm x-rays, using 'just' a Beryllium screen in front of the pi CCD sensor ought to do the trick (remove all lenses, IR filters, etc, so the chip is exposed for maximum sensitivity). The Scintillation crystal could in theory work like a lens, but I'm not 100% on that, but it will definitively detect ionizing radiation and give off visible light for the camera to see.
I would recommend reading "The suitability of smartphone camera sensors for detecting radiation" in Scientific Reports from Nature, to shed some light on the subject ;ø)
Beware if going this route, Beryllium isn't your friend - so handle with utmost care..
I used to try to make a youtube channel myself and people liked my stuff, telling me not to quit. So here I am. Don't quit.
Good stuff. Interested to see more
I’ve been using UA-cam since 2004ish… this is the coolest channel I’ve ran into.
Interesting experiment, looking forward for more!
Who warned you of x-rays at 3 kV?!? Asides from the fact that it's extremely unlikely to generate x-rays at that acceleration voltage (albeit not impossible), they'd be of extremely low photon energy. I might add that if you manage to generate x-rays of < 3 keV photon energy, I doubt your x-ray screen would emit any light from it. P.S. Subscribed!
Such a handsome xplosion!
Why such a huge battery of electrolytic low capacitors with high inductance? you ideally need one oil capacitor 20 nanohenry 60 kilovolts 10 microfarads with instant current output in megaamps
Hi. I have certainly x-rayed myself a few times lol woops. Not too high levels and not often but you've got me thinking I'd better get a dosimeter I think.
Just recently , I placed dibs on 3 large glass panels from an x-ray department . When i asked about them they told me they'd smashed them because they were too hard to get out and they were "only glass". I am so upset . If I'd had known I'd have got out myself. Just thought I might share this with someone who would understand how messed up this is.
Yay I love working in construction.
مهتم بكل التفصيل
quite funny, i am currently working on a electrothermal accelerator using a pretty similar capacitor bank to yours but was struggling with coming up with a proper switch for it, most of my trials were done using a mechanical switch but as you mentioned they get pretty loud...
The idea of using a vacuum switch like that never came up but it is a pretty good idea that i should try sometime
3Kv ? I wouldn`t worry about X rays at all... nice set up! sorry it got fried! :( .. tell you what! you`ve earned a new sub!
At 3kv i dont think the electrons have enough energy to produce any x-rays at all. Amazing setup though. Gained a new sub
Have you tried using diodes to prevent current backflow? Also, (I don't know how to put this to make it sound friendly, but I am trying to be) may I ask why you didn't choose to use photosensitive paper? And one more thing: for a steady plasma stream, try using a neon light tube, or (if you don't want to modify your setup all too much) the townsend discharge method.
Im not sure if backflow diodes would be useful in this situation since the failure mode was from an arc jumping from the circuit to ground. My current fix is to isolate the vacuum switch from the relay with a long plastic tube and use enamel coating on metal components to prevent the arc discharge while its under vacuum. The problem with photosensitive paper is it has a very long exposure time (minutes) where as the xray pulse lasts in the tens of microseconds. A neon tube is not customizable and is at relatively high pressures (0.4 - 3 kPa).
For the townsend discharge method, the vacuum switch actually uses that method and is very efficient.
@@NeutronStudios1 Oh, I read somewhere on researchgate that laser pulses of duration 1.2 picoseconds would cause a mark to be visible on the paper but chances are that either the laser wattage was high, or I misunderstood it. Good video!
@@NeutronStudios1Please could you make a video on hydrogen plasma
would a cheap dosimeter work to pick up a short flux?
unfortunately no, I have a cheap dosimeter and it doesn't pick up a noticeable change from these experiments.
You should put a little hydrogen ball in there 😈
