  The Taiwanese-American Occultation Survey (TAOS) aims to detect serendipitous
occultations of stars by small (about 1 km diameter) objects in the Kuiper Belt
and beyond. Such events are very rare (<0.001 events per star per year) and
short in duration (about 200 ms), so many stars must be monitored at a high
readout cadence. TAOS monitors typically around 500 stars simultaneously at a 5
Hz readout cadence with four telescopes located at Lulin Observatory in central
Taiwan. In this paper, we report the results of the search for small Kuiper
Belt Objects (KBOs) in seven years of data. No occultation events were found,
resulting in a 95% c.l. upper limit on the slope of the faint end of the KBO
size distribution of q = 3.34 to 3.82, depending on the surface density at the
break in the size distribution at a diameter of about 90 km.
