Electron beam system of the Tevatron Electron Lens

The goal of the beam-beam compensation project at Fermalb is to improve performance of the Tevatron collider. The first of the two Tevatron Electron Lens (TEL) for betatron tune correction of individual antiproton bunches has been recently built, commissioned and installed in the Tevatron. The first series of studies demonstrated a good agreement of the tuneshift of 980 GeV protons with theory. We describe the electron beam system of the TEL, which includes vacuum system, electron gun, collector, ion and secondary electron cleaning electrodes, beam diagnostics (BPMs, current monitors, scrapers, wire scanner). The results of the electron beam studies are presented.
