  We have performed a survey of the Kuiper belt covering ~ 1/3 a square degree
of the sky using Suprime-cam on the Subaru telescope, to a limiting magnitude
of m(R)~ 26.8 (50% threshold) and have found 36 new KBOs. We have confirmed
that the luminosity function of the Kuiper belt must break as previously
observed (Bernstein et al. 2004; Fuentes & Holman 2008). From the luminosity
function, we have inferred the underlying size distribution and find that it is
consistent with a large object power-law slope q1~4.8 that breaks to a slope
q2~1.9 at object diameter Db~60 km assuming 6% albedos. We have found no
conclusive evidence that the size distribution of KBOs with inclinations i<5 is
different than that of those with i>5. We discuss implications of this
measurement for early accretion in the outer solar system and Neptune migration
scenarios.
