  We plan to take advantage of the unprecedented combination of low thermal
background and high resolution provided by the 6.5m MMT's adaptive secondary
mirror, to target the 3-5 micron atmospheric window where giant planets are
expected to be anomalously bright. We are in the process of building a 3-5
micron coronograph that is predicted to be sensitive to planets as close as 0.4
arcsec to the parent star. We expect to be able to detect giant planets down to
5 times Jupiter's mass for a 1 Gyr old system at 10 pc. We plan to carry out a
survey which is complementary to the radial velocity detections of planets and
constructed to characterize the prevalence and distribution of giant planets
around nearby, Sun-like stars.
