Intensifying screen
« on: April 19, 2021, 04:45:03 PM »
Hi everyone!
I build an x ray machine with an 2u2c Russian copy of 2x2a tube. It works very well, but the problem is I don't have an intensifying screen and its pretty hard for me to find one. What I can use as an intensifying screen? Maybe I can build one but I don't know what chemicals and stuff i need.
Here is an video of the x rays attacking the camera ccd (and the Geiger counter in the background): https://imgur.com/gallery/yYIikrv
 
Thanks in advance!

Something like this?

I don't think it's viable making one yourself

Beware that many "phosphor plates" used for radiography do not glow at all when irradiated by x-rays.
They receive a latent image, later "developed" in a plate reading machine, with the plate reset and ready for the next exposure.
