The Electron Lens upgrade project at the Relativistic Heavy Ion Collider (RHIC) has reached an operational status, whereby intense, pulsed or DC beams of electrons are generated in order to interact with the RHIC polarized proton beams in both the Blue and Yellow Rings at the 10 o'clock Interaction Region. Interactions between the electrons and protons are utilized to counteract the beam-beam effect that arises from the desired polarized proton collisions, which result in a higher RHIC luminosity. A complex system for operating the e-lens has been developed, including superconducting and non-superconducting magnet controls, instrumentation systems, a COTS-based Machine Protection System, custom Blue and Yellow e-lens timing systems for synchronizing the electron beam with the RHIC timing system, beam alignment software tools for maximizing electron-proton collisions, as well as complex user interfaces to support routine operation of the system. e-lens software and hardware design will be presented, as well as recent updates to the system that were required in order to meet changing system requirements in preparation for the first operational run of the system.
