btw qns your videos may be crap, but you certainly have a talent for engineering. you should try colliding electrons with photons; that will be my next.
@BulgarianBombShelter Thanks. If i collided electrons with photons i'm pretty sure they would bounce off each other or the electrons would absorbe the photons, but when i gel a vacuum pump ill try it for sure.
The electron guns in projection CRTs are more badass than that one. It's a larger gun with a single beam designed for high intensity such as a projector, instead of the standard gun there with three beams each for red green and blue. I had one of those tubes a few years back, plugged it into a regular CRT board and used that set's deflection coils and anode flyback connector. I had something on it until one of the pins broke off the base when I unplugged it from the CRT board.
@quicknuclearscience I can't exactly put a figure on it. But I do know the tube requires liquid cooling of the faceplate when it's operated in it's intended environment. I've had some other tubes nearly self-destruct when leaving an undeflected spot on the screen. The beam would drill into the faceplate. I would imagine the beam in a projection tube would do the same thing very quickly and drill all the way through in a short amount of time.
@quicknuclearscience There's a boat load of them in ebay right now. The best ones to snatch in your case anyway are the ones showing more wear than the others. The wear is so intense and uneven that it is not practical to return to service in another CRT projector, since the raster settings may be different. These are the ones that most people looking for replacements should stay away from anyway for that reason. ;)
you do know in the process of this in order to get the particles at the speed of light your going to need more then pvp pipe your going to need to make the opening for the particles to travel through the size of an atom and your also going to need to have a 3 stage process to get them up to speed or it wont be called a particle accelerator. plus your also making a mini black-hole for one one thousand of a second just to let u know about the extream radiation that it will give off.
@brandonhughes7 my goal here isn't to accelerate electrons to almost the speed of light, also a particle accelerator is anything that accelerates particles at all not something that accelerates them close to the speed of light. And i already know about the radiation it will give off, but because i haven't cut off the electron gun the lead coating on the CRT TV will still be intact it will protect from most of the radiation. Making the accelerator no more dangerous than a CRT TV.
I research particle physics, so trust me when I say, all this will do is create a type of oscilloscope. These electrons will only travel at about .5c, obviously not approaching anywhere near the speed of light, and consequently, not really accelerating anything. And even if you did manage to build a decent accelerator, you cannot accelerate electrons. CERN will accelerate protons by ionizing a hydrogen atom. simply put, electrons behave very strangely when we accelerate them, protons don't.
@103kon i know that playing with the beam will only create a sort of oscillliscope, but when slamming two beams together the electrons should bounce off each other and be detectable, right? I think it would be interesting to see how they bounce off each other. And yes you can accelerate electrons, just look at the LEP.
@quicknuclearscience Yes, if you have the proper equipment you will be able to "see" electrons interacting. But this is basic Quantum mechanics. Of course electrons can be accelerated, but YOU cannot. The reason the LEP works is because it's so big. They need the 27kilometer path to allow the electrons to build up enough energy over time, and this is extraordinarily difficult to achieve. Have you done the math? If you have, you'll see the difficulties very quickly.
@quicknuclearscience As electrons accelerate, they become extraordinarily more massive. Consequently, the closer to the speed of light they become, the more energy is required to exert the force required to continue to accelerate them. This process takes A LOT of energy, over a long period of time, over the course a LONG distance, and you would need to regulate its oscillation with an extreme degree of precision.
@quicknuclearscience The nature of the electron makes its acceleration far more difficult to achieve than that of a proton. You could invest all this time, money, and energy in trying to accelerate electrons. Or you could invest in HV generators, transformers, etc. and actually build a potential drop accelerator. It would prove much easier, more fruitful, and likely much cheaper. Also note that when accelerated, electrons emit BETA RADIATION which can be harmful and difficult to detect.
@quicknuclearscience None, just a few tips. 1) Only move the camera if you really have to 2) Keep it on a tripod and 3) maintain a wide view so you can use both your hands on your project :D Just basically keep it still, other than that when you film, RELAX :D good luck
@tunderhed Thanks for the tips, i have a tripod but it is 6 inches high, i'll try the wide angle, sounds like it might work, and i defiantly need to Relax. Thanks
Very bright young man. Keep at it and someday contribute to science. I admire you kid. Be careful because the CRT can keep a lethal charge even after power has been removed for up to 3 days. You can make a simple flyback driver. There are schematic for that.
@TheMarineGuy4000 actually i'm not sure that this is legal now that you mention it. But it has no reason to be illegal, it cant possibly harm somebody. Except me and my chances of getting a girlfriend.
This is an excellent project which will provide valuable insight into particle physics, vacuum technology, electron gun design, and general engineering. After watching your video, I have two suggestions for you. Do not use PVC for your drift tube. Its extremely leaky and will cause you nothing but headaches. Heavy walled Pyrex or borosilicate tubing is in order here. A little internet research here can provide suitable equivanencies. Secondly, use an electron gun from a magnetron.
@clagwell oh i'll try to get some of the pyrex, and for the electron gun i already have two crt tv's with electron guns that i was going to use, and collide the beams, instead of colliding 1 beam with a static target as in the video above. I could try to get some magnetron's but just curious why from a magnetron are they better in some way?
@clagwell The filament from a CRT gun will quickly fail after being exposed to air. A magnetron gun is extremely heavy duty and will withstand the air exposure with no problem. Not to mention, you could run the magnetron gun at much higher temps providing more electrons through thermionic emisson.
Regarding "Episode 3", I have taken a break from lab projects for awhile. I will finish the project later this year and post a new video (or two).
@clagwell thanks that will save me a ton, i'm not sure i can get any magnetron gun's though but i'll try. Can't wait for the your new particle accelerator video, good luck.

how much more intense is the beam, i would assume an order of magnitude.
