Good questions!

Not exactly off topic.

The electrons are traveling in pretty small packets. Eventually they get
too close to one another, and they repel one another and get pushed out of
the packet.

If it's "top-up" filling, the little bumps could cause a problem. Ask
the beam-line manager.
If it's periodic refilling, every several hours, you don't take data
during the filling time, so when you restart you'll find a new, stronger
beam. That increase in intensity ought to be corrected in the scale
factors when you reduce data. (There is more to it than this, and maybe
you'll get more answers.)

Not impossible. Just takes money.
