As for "this thing probably is never going to work", take a look at this:

yes, invisible things that can kill you without your notice should be
treated with the degree of respect they deserve. Not necessarily more
dangerous than turning on a disassembled microwave oven though.

I'm all in favor of avoiding exposure to x-rays.
I'd say this thing
probably is never going to work, and might make an interesting art project
or something.
If people are serious about attempting to make it work as an x-ray source,
there would need to be a clear plan about how people would be protected
from it. And I suspect that the time while the fix is being attempted, that
is the most likely time to have accidental exposure to x-rays, so
protection would need to come first.
Probably requires building some sort of lead lined enclosure around the
thing with safety interlocks to make sure the door is closed before it can
turn on, and that would probably be pretty expensive.
But if people are really into it, and can put up the money to make it
happen...then the idea should be considered.

Thanks Steve, those lead shields are useful in
minimizing radiation
exposure in a clinical setting but unfortunately in a hacker space I would
probably classify having an active X-ray source as a hazardous danger. I'm
not against controlled risks but there is a very real risk of inadvertantly
exposing other occupants to X-rays (even accidentally) and that could be a
problem. Similar to some of the biowork that a few of us are hoping to do,
we have to be really careful to ensure Sudo room is a physically safe
enviroment (within reason) for all members, even if that means some things
may not be possible in our shared space and I would feel a little
uncomfortable with an active X-ray source being used (even if I'm in the
other room).
Does anyone have any additional thoughts on this? I'm not an X-ray (or
radiation) expert but I just wanted to chime in around the safety
considerations that I thought might be important for us!

In theory this thing first actually work.
He was unable to meet up yesterday so someone still needs to pick it up.
