Abstract

The Photoconductor Array Camera and Spectrometer is one of the three proposed instruments for ESA's Far IR and Submillimeter Telescope. It employs two 16 by 25 pixels Ge:Ga photoconductor arrays to perform imaging photometry and imaging line spectroscopy in the 80-210 micrometers wavelength band, with optional extensions to 60 micrometers and approximately 300 micrometers . In photometry mode, it will simultaneously image two bands, 80-130 micrometers and 130-210 micrometers , over fields of view of approximately 1 foot by 1.5 feet and approximately 2 feet by 3 feet, respectively, with full beam sampling in each band. In spectroscopy mode, it will image a field of approximately 50 inches by 50 inches, resolved into 5 by 5 pixels, with an instantaneous spectral coverage of approximately 1500 km/s and a spectral resolution of approximately 175 km/s. In both modes background-noise limited performance is expected, with sensitivities of 3.5-5 mJy or 2.5 by 10^-18/m², respectively.
