Another parameter is the bending limit Kb, expressing the (magnetic field) strength of the cyclotron. Rewriting the formula for the kinetic energy one gets
- T = p2 / 2m = (qBR)2 / 2m
where R is the extraction radius, q (m) the charge (mass) of the particle and B the strength of the field. Because the magnet coils have a limiting current, there is an upper bound on the magnetic field, which means the kinetic energy of the accelerated particle is bounded by
- T / A < Kb (Z / A) 2
- Kb = (eBR)2 / 2m0
with e the electron charge and m0 the proton rest mass. The bending limit for AGOR is 600 MeV, which makes it a K600 cyclotron, as it is also called.
