  We present preliminary results from a FUV spectroscopic and photometric
survey of the globular cluster 47 Tuc. Our main goal is to either confirm or
rule out the existence of a large population of CVs in the core of this
cluster.
  We have so far identified approximately 425 FUV sources, most of which are
probably hot, young WDs. However, we have also found approximately 30 FUV
sources whose position in a FUV-optical color-magnitude diagram makes them
strong CV candidates. If most or all of these objects are eventually confirmed
as CVs, the large CV population predicted by tidal capture theory has finally
been found.
  Our data has also allowed us to resolve the long-standing puzzle surrounding
AKO 9, a UV-bright and highly variable 1.1 day binary system in 47 Tuc. AKO 9
is the brightest FUV source in our data and presents a blue FUV spectrum with
strong CIV and HeII emission lines. Its spectrum is similar to that of the
long-period, DN-type field CV GK Per. Based on this similarity and other
evidence, we suggest that AKO 9 is a long-period CV in which mass-transfer is
driven by the nuclear evolution of a sub-giant donor star.
