Abstract: The Photodetector Array Camera and Spectrometer (PACS) is one of the three science instruments for ESA's far infrared and submillimetre observatory, Herschel. It employs two Ge:Ga photoconductor arrays (stressed and unstressed) with 16 x 25 pixels, each, and two filled Si bolometer arrays with 16 x 32 and 32 x 64 pixels, respectively to perform imaging line spectroscopy and imaging photometry in the 57 - 210mum wavelength band. In photometry mode, it will simultaneously image two bands, 60 - 85mum or 85 - 130mum and 130 - 210mum, over a field of view of similar to 1.75' x 3.5'. with full beam sampling in each band. In spectroscopy mode, it will image a field of similar to 50" x 50", resolved into 5 x 5 pixels, with an instantaneous spectral coverage of similar to 1500km/s and a spectral resolution of similar to 75 - 300km/s. In both modes background-noise limited peformance is expected, with sensitivities (5sigma in 1h) of similar to 3 mJy or 3 - 10 x 10(-18)W/m(2), respectively.
