The long term performance of Tevatron Electron Lenses (TEL1 and TEL2) are summarized. Both of them are operated reliably. Besides their main function as DC beam cleaner, TEL2 is also a test bed for beam-beam compensation, space charge compensator and soft collimator. And its operation as collimator will be tested after the installation of the new electron gun with hollow cathode in planed summer shutdown peroid.

In present circular machines the beam intensity is often limited by the following phenomena: machine resonances, various tune shifts (and spreads), and instabilities. In this paper we will propose a path toward alleviating these phenomena by making accelerators nonlinear as well as integrable.
