Effect of electron disruption in the energy recovery linac based electron ion collider
Beam-beam effects present one of the major factors limiting the luminosity of colliders. In the energy recovery linac (ERL) based eRHIC design, the electron beam, accelerated in a superconducting ERL, collides with the proton beam circulating in the RHIC ring. During such collisions the electron beam undergoes a very strong beam-beam interaction with the protons, which warrants careful examination. We evaluated transverse disruption and linear mismatch effects in the electron beam caused by collisions and considered several countermeasures to mitigate the emittance growth from these interactions. The minimum required aperture of transport lines is calculated that should allow the transport of the electron beam during the deceleration process.
