  The two Tevatron Electron Lenses (TEL1 and TEL2) are installed in Tevatron in
2001 and 2006 respectively. TEL1 is operated as the vital parts of the Tevatron
for abort gap beam clearing, while TEL2 is functioning as the backup as well as
the test device for beam-beam compensation, space charge compensator and soft
beam collimator. Both of them are working exceptionally reliable after a few
initial kinks being worked out. Their operations in Tevatron are summarized in
this report.
