As far as the PTF concerns,various beam energies are needed to ensure an effective radiation of tumors located at different depths.On account of the fact that the rotation radius is constant,the field of dipoles should change according to the beam energy.The correlation between the field intensity and the beam energy is described by Eq.(1).The higher the beam energy,the higher the magnetic field needed to maintain a constant radius.Therefore,as to the EM force analysis,it is necessary to focus only on the maximum input currents,which are summarized in Table 2.The seven quadrupoles are classified by magnetic field gradient(the threshold is 12 T/m)into two groups.Quadrupoles of the same group adopt the same mechanical structure.
