Abstract :
The Tevatron Electron Lens (TEL) installed in the Tevatron at FNAL bends a 10-keV electron beam into and out of the antiproton path. The stringent requirements of the electron beam path demand extremely straight magnetic field lines over roughly two meters which then bend away to the gun and collector. A 6-Tesla superconducting solenoid and two normal-conducting solenoids, supplemented with several dipole and quadrupole correctors, were constructed at IHEP and subsequently assembled and tested at FNAL. Several testing methods, with an resolution of approximately 2 grad, confirmed the field profile to match computer models and meet necessary constraints. Visual inspection of the beam position and size on screens confirmed the measurements. This paper analyzes these results and relates them to the system requirements
