  A proposal to search for direct {\mu}-->e conversion at Fermilab requires
slow, resonant extraction of an intense proton beam. Large space charge forces
will present challenges, partly due to the substantial betatron tune spread.
The main challenges will be maintaining a uniform spill profile and moderate
losses at the septum. We propose to use "radio frequency knockout" (RFKO) for
fine tuning the extraction. Strategies for the use of the RFKO method will be
discussed here in the context of the Mu2e experiment. The feasibility of this
method has been demonstrated in simulations.
