Abstract :
It is planned to overcome the major limitation imposed by the beam-beam effect on the achievable luminosity in Tevatron with the help of electron lenses; the primary goal being to eliminate the p-bar bunch-to-bunch tunespread due to the PACMAN effect (linear beam-beam compensation). The possibility of the simultaneous compression - by adjusting the electron beam profile - of the intrabunch nonlinear tunespread (nonlinear compensation) is considered. Major limitations on the achievable degree of compression are analyzed
