Coupling effect on the proton optics from the electron lenses
In this note we calculate the effect of the electron lense solenoids on the proton optics. Electron lenses (e-lenses) are to be used for head-on beam-beam compensation in the Relativistic Heavy Ion Collider (RHIC). Electron lenses are to be used for head-on beam-beam compensation in the polarized proton (pp) runs to compensate the large tune spread generated by the head-on proton-proton beam-beam interactions at IP6 and IP8 in the Relativistic Heavy Ion Collider (RHIC). The main part of an electron lens is a superconducting solenoid with a longitudinal magnetic field up to 6 T. In this report, we will estimate the e-elenses effects on the {beta} and dispersion functions with 100 GeV and 250 GeV pp run lattices. Table 1 lists some lattice and beam parameters to be used in the following study.
