  Using a suite of numerical calculations, we consider the long-term evolution
of circumbinary debris from the Pluto-Charon giant impact. Initially, these
solids have large eccentricity and pericenters near Charon's orbit. On time
scales of 100-1000 yr, dynamical interactions with Pluto and Charon lead to the
ejection of most solids from the system. As the dynamics moves particles away
from the barycenter, collisional damping reduces the orbital eccentricity of
many particles. These solids populate a circumbinary disk in the Pluto-Charon
orbital plane; a large fraction of this material lies within a `satellite zone'
that encompasses the orbits of Styx, Nix, Kerberos, and Hydra. Compared to the
narrow rings generated from the debris of a collision between a trans-Neptunian
object (TNO) and Charon, disks produced after the giant impact are much more
extended and may be a less promising option for producing small circumbinary
satellites.
