  Fermilab Main Injector has been operating at high Beam Power levels since
2008 when multi-batch slip stacking became operational. In order to maintain
and increase the beam power levels the localized beam loss due to beam left
over in the injection kicker gap during slip stacking needs to be addressed. A
set of gap clearing kickers that kick any beam left in the injection gap to the
beam abort have been built. The kickers were installed in the summer of 2009
and became operational in November of 2010. The kicker performance and its
effect on the beam losses will be described.
