In this follow-up video, I show that I was able to get a P47 phosphor disc to illuminate when unrolling tape in the vacuum chamber. The blue x-ray intensifier screen did not illuminate although it was also in the chamber. Also, it seems the P47 was illuminated through a thin copper foil, though I will have to do some more tests to believe this.
