Abstract: Applying the space-charge forces of a low-energy electron beam can lead to asignificant improvement of the beam-particle lifetime limit arising from thebeam-beam interaction in a high-energy collider 1. In this article we presentthe results of various beam experiments with electron lenses, novel instrumentsdeveloped for the beam-beam compensation at the Tevatron, which collides980-GeV proton and antiproton beams. We study the dependencies of the particlebetatron tunes on the electron beam current, energy and position; we explorethe effects of electron-beam imperfections and noises; and we quantify theimprovements of the high-energy beam intensity and the collider luminositylifetime obtained by the action of the Tevatron Electron Lenses.
