Abstract / Description: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_25 pixels, each, and two filled Si bolometer arrays with 16_32 and 32_64 pixels, respectively, to perform imagiung 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 ~1.75'_3.5', with full beam sampling in each band. In spectroscopy mode, it will image a field of ~50"_50", resolved into 5_5 pixels, with an instantaneous spectral coverage of ~600- 2500 km/s and a spectral resolution of ~75-300 km/s. In both modes background-noise limited performance is expected, with sensitivities (5sigma in 1h) of ~3 mJy or 3- 20_10-18W/m2, respectively.
