Hi, does any one try and succeeded by making crystal diffraction picture on intensifying screen ? I want to try do it like this: take salt crystal, drill 0,8-1mm hole in lead sheet 2-3mm thick, and place intensifying screen 5-10cm away from lead sheet, and with good camera (1000iso, 2,8, 30s or even more for exposure) take picture, and hopeful get some nice pattern of crystal :) i have quite concentrated 80-120KV x ray source ( well, not yet, but soon) Will it work ??

Which I mount like this:
I would also suggest you fix your Gd2O2S:Tb screen to the front of an image intensifier, to avoid very long exposure periods.

that wasin't that hard, all i did i take around 6cm steel wall, drill hole 2mm in diameter, used some nice mononcrystall from mosfet, and 2 min exposition with intensifying screen, and after developing film i get this
