Abstrakt

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 imaging line spectroscopy and imaging photometry in the 57 - 210/œm wavelength band. In photometry mode, it will simultaneously image two bands, 60 - 85œm or 85 - 130œm and 130 - 210œm, 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 ~ 1500km/s and a spectral resolution of ~ 75 - 300km/s. In both modes background-noise limited peformance is expected, with sensitivities (5s in 1h) of ~ 3 mJy or 3 - 10 × 10-18W/m2, respectively.
