PROGRESS WITH ELECTRON BEAM SYSTEM FOR THE TEVATRON ELECTRON LENSES

The Tevatron Electron Lenses (TELs) were installed to mitigate the effects of electromagnetic long-range and head-on interactions of high intensity proton and antiproton beams. These phenomena account for significant beam loss and lifetime limitations in the Tevatron Collider operation. The electron guns and their drivers are key components of the TELs. They define the possible modes of operation and overall performance of the TELs. We report on the recent development of the electron guns and the gun driver for the Tevatron Electron Lenses.
