Attempting to make X-rays by unrolling Scotch tape (negative result)--- make money online

A few years ago, a research group posted a video showing that X-rays could be created by unrolling scotch tape in a vacuum. The idea is that the static charge generated by the mechanical unrolling process would cause electrons to

accelerate to 50KV (or so), and then produce x-rays when they slam into something. I tried to recreate this experiment, but I had pretty weak results. I may need a much larger vacuum pump to keep the pressure in the chamber very low while unrolling.
hey everyone here's an experiment that

I've wanted to try for a long time and

someone mentioned it in the comments at

my last video which had brought it to

the front of my memory a few years ago

someone said that you could generate

x-rays by unrolling a roll of scotch

tape in a vacuum and surprisingly

there's there's been no follow-up like I

haven't seen any stories about this

lately the original research group

thought that this could be a low-cost

alternative for x-ray machines because

obviously you can just send a spool of

tape to third-world countries of vacuum

chamber and generate low-cost x-rays so

I want to give this a shot that it's

supposed to work by transferring charge

from one roll of tape to the piece that

you're pulling off so that there's a

really high charge differential between

the piece of tape that's getting pulled

off in the roll like potentially 50

kilovolts and then when the electrons

you know fly off the tape and hit the

roll they decelerate and create x-rays

I've always been a little bit skeptical

but of course trying it's always better

so what I did is I started with an

aluminium plate and put a teflon seal in

it so I drilled a two-step counterbore

one of the counter bores is to hold this

Teflon spring-loaded seal and the other

counterbore is to hold a ball bearing so

to do this right I should have a ball

bearing on the top and bottom of the

plate with the seal in the middle

but this is just kind of a quick pack

job and I put a take up school on the

top of the plate and a collar on the

bottom to keep it from getting sucked in

there's going to be vacuum on the inside

and air pressure on the outside so it

will be some force trying to pull the

shaft in and then to dispense the tape I

just have a free-floating roller with a

tape roll line I also have my pen engage

mounted into the plate and I used a

acrylic tube to seal the plate to the

diffusion pump this is a new diffusion

pump that I got it halts head and it's

water-cooled so I've got my air

conditioner water chiller running and

it's pumping water through the pump I've

got the Harbor Freight vacuum pump

two-stage rotary pump and that's pumping

the chamber down

as you can see the vacuum is not as as

good as I would like it to be the tape

is outgassing quite a bit so if you keep

an eye on the gauge if I turn the tape

roll very slightly to dispense some tape

you can see there's quite a bit of gas

released you can see there the gauge

change just from unrolling you know a

few centimeters of tape so we're gonna

have to try this in short bursts but I'm

going to use is a cordless drill to turn

the spool and get some tape dispensed

to check if this thing is actually

making x-rays I've got the handy-dandy

mighty own Geiger counter and my x-ray

intensifier cassette phosphor screen

behind this whole rig so I'm going to

turn the room lights down and hook the

cordless drill up to the tape dispenser

and roll off some tape and I'll do it in

short bursts to try to keep the air

pressure while the vacuum really good in

the chamber and we'll see what we can

see so the vacuum level is only about 2

times 10 to the negative 4

tor and I'm going to give it a quick

pulse here with the drill

well I'm not sure you were able to see

anything I did notice some blue light

coming from the tape roll itself but not

from the phosphor screen and the Geiger

counter seemed to be a little bit more

active when I was unrolling but honestly

I don't really see the effect all that

strongly it could be there so

unfortunately this test is pretty

uncommon inconclusive

maybe with a better vacuum pump I'll be

able to maintain a higher vacuum while

unrolling the tape okay I'll keep you
