Abstract

We describe a 32 pixel polarimeter, Hertz, for use at the Caltech Submillimeter Observatory. We present polarization maps of the Orion molecular cloud (OMC-1) at 350 μm (46 detections) and 450 μm (19 detections) with 3σ or better statistical significance. The 350 μm polarization ranges from 1.4% to 6.8% with a median value of 3.3%. The position angles are fairly uniform across the source at an angle of ∼30 degrees (east of north). We describe the design and performance characteristics of the polarimeter and discuss systematic effects due to telescope and instrumental polarization, atmospheric fluctuations, and reference beam flux.
