Making Super Fast Electrons, Cathode Ray 

I ruined the 69

Yeah, welcome to electroboom

To be fair, I wouldn’t exactly call it “safe”.

I thought I was the only one who noticed!

So I’m not the only one

As engineer, he knows that the dome is perfectly safe unless some external force affects it... ^^

@@timohaavisto8491 I was mostly worried he would bump into the table to create that force

Total anxiety inducing +_+;

With lighter*

thanks for the idea

Intentions are what matters. Smart people are not who should be placed on a watchlist. Evil, cold, or profit-driven people should, though.

its probably already emitting some xrays, tungsten just has a bigger cross section for electron scattering

X-rays aren't very dangerous for short ammounts of time. No need for watchlist.

😂

My exact thoughts.... Here I come plasma based bladeless jet engine and gravity stabilized pure electron battery

@@sonicxfan8322 lol! I believe he said not to try this at home...unless..... you are not at home then that would void his warning XD.

A true engineer.

Sometimes it's just easier to just go for it and learn from it than to go though a search engine for a niche answer.

Yep

Same here I love cathode rays even more when it’s pure and turned a light blue and gets stripes :)

trump wasn’t asked

his mic turned into a bomb lol

@MUM!N i dont think you can catch That With a comercially available camera

nah Vaccum Tubes barely make Xrays

@MUM!N You need a purpose build X Ray machine and a purpose build X Ray tube to get significant amounts of radiation. 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.

@@alouisschafer7212 idk much about this but don't vacuum tubes work at a couple hundred volts? Electroboom is using tens of thousands of volts

@@maxxiang8746 you are correct that is one of the main factors. Normal vacuum tubes often barely see 500V. So almost no X Rays. Seeing 1000V in a Tube Amp is rare. Highest I ever worked with was 450V which is not much in contrast to thousands of volts but still a change of pace to work with from conventional electronics.

when i use my vacuum its affects the lights...

It MESSES with mY LIGHTS!! so calm

I checked the comments specifically to see if anyone else noticed this.

Yeah, was just going to post this, looking at that fills me with incredible levels of anxiety.

Xdddd

I had the same though and then I went to remember that this is a desk of a guy who tests his home-made vacuum chamber without even having a proper eye protection and the only method of testing high-voltage devices he know is to do it with his hand. That globe placement was pretty safe for his standards.

It didn't annoy me, but with many people mentioning it now its annoying thanks guys

hes done this in the video where he made his vacuum chamber...

With a perfect seal, what level of vacuum is this pump capable of?

I'd like to like this comment, but its at 69 nice

Or maybe: "Let's power it up"

Now lets see if this works

thats what she said

I feel like I hear "Let's try it" more than anything 😆

He's very likely producing tons of xrays

Electromagnetic radiation go brrr, ik it's a joke but the concentration decreases with inverse cube of distance so he's only risking himself

@Nybbl er Have you seen his Eyebrows? guy could impregnarte someone with a Hard stare.

well,i do experiment with homemade gunpowder,gasoline,etc,and i have made some rockets,biggest one wighed around 6 kilos,which is a lot,at least for me,but i am nowhere near the exosphere or any space,so it would be useless in my research,very cool though!

"OUCH!"

OH F### *** **** *bleep* BURNED MY FINGER

But it started out as a Farnsworth fusor....

IT BERNS

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.

@@ArchangelUltra i feel like a smartypants rn

That is why old CRT screens had an earthed screen to ground out the x-rays.

@@dogwalker666 You're gonna have to explain this one to me. X-rays are uncharged so why would they need any kind of ground? They're unaffected by electric potentials. And I thought CRTs didn't have much of an xray problem because their electron gun wasn't at a very high voltage, but I don't actually know much about those so that's more of a guess.

@@ArchangelUltra Thanks I was wondering what that phenomena was. Now I'm going to dive into a Wikipedia rabbit hole. See you guys on the other side. o7

@@ElectroBOOM Hey Mehdi in my book it is written that if we use cathode tube for very long it can break. Can you explain this, maybe it is due to the vacuum?

I wouldn't worry too much most x-rays are in the Mev range. In the 100xKev range they are asorbed by air in a few inches. Just like old TVs not really scary unless you sit 2 inches from it all day every day.

@@pcriged you’re sort of right. most x rays can arrange from 70-400 KV. You can seriously create some decent x rays. I know this because I graduated from radiology, and I work with x rays. (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

@@CapDude death insurance not health insurance

@Tristan Sword ya

the dose makes the poison, I guess 😂🔥

@@VigiHunter yes the lethality is equal to time x strength

​@@arthurizando 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.

@@Ahapenootjes o know, just trying to be brief

@@Ahapenootjes This is part of my field of study, I just didn't want do drag on in a simple RU-vid comment joke :).

That's something cody's lab would do.

LMAO

@@24680kong they both are subbed to each other lol

It would cause the wave function to collapse

@@AlexMoreno-zj7po If you believe in such nonsense as the wave function collapse

That's cool

Also they paint the inner tube with silver to stop the xrays that it produces

Same thing with beam tetrodes/pentodes which contain beam forming plates.

@@brokentos4546 the conducting metal inside the CRT is where the +25 kv is applied. It sucks the electron out after they hit the phosphor. The xray are stopped by the lead in the glass. The focussed electron beam is created by the succession of metal plates in the electron gun, including the focus control with a voltage of about +8 kv.
