Good questions!
I have off topic questions.
Not exactly off topic.
Why can't electrons continuously circulate the ring at synchrotrons instead being refilled every few hours?
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.
Does new electrons injected into the ring affect MX data collection?
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.)
Secondly, is it impossible to have all MX beamlines with insertion device as the source and all of them tunable?
Not impossible. Just takes money. Bob
