Hi guys ,
Suppose there is a circular accelerator has the same inner structure of a linear accelerator in terms of the rings of acceleration ...

Not sure what you are imagining here:
I think of a
linear accelerator like that (link) ... so the picture I get is somehow putting the rings in a circle. But this uses electric fields so...
The angular frequency of accelerated particles is : ω = qB/m = 2πf , and this is also the frequency of the supplied current ...

... I'm not sure where the B comes in to it.
