Abstract
The Cerro­ Chajnantor Atacama Telescope prime (CCAT-p) Observatory is a wide­field, 6­ meter aperture submillimeter telescope. Prime-­Cam ­will be a powerful, first­ light camera for CCAT-p with imagers working at several wavelengths and a spectroscopic instrument aimed at intensity mapping during the epoch of reionization. We present the design of an instrument module in Prime­-Cam, operating at 350 microns — the shortest wavelength on the instrument, and the most novel for astronomical surveys, taking full advantage of the atmospheric transparency at the high 5600 meter CCAT-p siting on Cerro Chajnantor. This instrument module will provide unprecedented broadband intensity and polarization measurement capabilities to address pressing astrophysical questions regarding galaxy formation, Big Bang cosmology, and star formation within our own Galaxy. We present the overall optical and mechanical design for the module, and laboratory characterization of the 860-GHz KID array.
