Abstract
We have imaged a 6 arcminute region in the Bo\"otes Deep Field using the 350 m-optimised second generation Submillimeter High Angular Resolution Camera (SHARC II), achieving a peak 1 sensitivity of 5 mJy. We detect three sources above 3, and determine a spurious source detection rate of 1.09 in our maps. In the absence of detections, we rely on deep 24 m and 20 cm imaging to deduce which sources are most likely to be genuine, giving two real sources. From this we derive an integral source count of 0.84 sources arcmin at mJy, which is consistent with 350 m source count models that have an IR-luminous galaxy population evolving with redshift. We use these constraints to consider the future for ground-based short-submillimetre surveys.
