Abstract
The Photoconductor Array Camera & Spectrometer (PACS) is one of the three science instruments for ESA's Far Infra-Red and Submillimeter Telescope (FIRST). It employs two 16 X 25 pixels Ge:Ga photoconductor arrays (stressed/unstressed) to perform imaging photometry and imaging line spectroscopy in the 60 - 210 micrometer wavelength band, with an optional extensions to approximately 300 micrometer. In photometry mode, it will simultaneously image two bands, 60 - 90 or 90 - 130 micrometer and 130 - 210 micrometer, over fields of view of approximately 1' X 1.5' and approximately 2' X 3', respectively, with full beam sampling in each band. In spectroscopy mode, it will image a field of approximately 50' X 50', resolved into 5 X 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 (5(sigma) in 1h) of 4 - 6 mJy or 3 X 10-18 W/m2, respectively.
