Abstract

OSS on Origins is designed to decode the cosmic history of nucleosynthesis, star formation, and supermassive black hole growth with wide-area spatial-spectral 3-D surveys in the 30 to 670 micron band. Six wideband grating modules combine to cover the full band at R=300, each couples a long slit with at least 30 beams on the sky. Two high-resolution modes are provided: one incorporates an interferometer in front of the gratings providing R of more than 40,000 at 112 microns, the other adds an etalon for R>300,000 at 112 microns. The full system design is presented, including optics, detector arrays, readouts, and the thermal design.
