Subject: How Electron Traps Work

I have some questions about betatron/Synchrotrons. My first is that is a 
betatron the best to contain electrons (Compared to a cyclotron, 
synchrocyclotron, etc)? My second is that how strong is the electric and 
magnets in the betatron/Synchrotrons? My third is what is the highest capacity 
of electrons in the betatron (not MeV but number)? My fourth is does the speed 
of the electrons moving in a circle make a difference? My fifth question is 
that if you have a betatron/Synchrotrons that has say 10 electrons in it, what 
does it mean that it has x MeV (In relation to amount of electrons in the 
system). My sixth question is that how long can I contain the electrons before 
I direct them to the target?  My last question is what is the energy lost by 
radiative energy loss, called synchrotron radiation (loss per time and 
electrons in system). My criterion is that the betatron/Synchrotrons be no 
bigger then 2 feet square (Structure similar to < 
http://adelphitech.com/products/narrowband_sources.html >, and the speed of 
the electrons is not as important as the capacity of electrons, Therefore, 
maximum electrons at resultant speed from electrons (before directing at 
target x ray/particles) Thanks.
