to compensate for the energy loss of the electron beam,
to keep the longitudinal stability,
and to determine the radius of the ring.
The energy loss per turn U is expressed as
where E is the energy of the beam in unit of GeV, r is the bending radium of dipole magnet.
There are four RF stations distributed along the ring.
Each station has eight accelerating cavities.
