摘要：

The Photodetector Array Camera and Spectrometer (PACS) is one of the three science instruments on ESA's far infrared and submillimetre observatory. It employs two Ge:Ga photoconductor arrays (stressed and unstressed) with 16 x 25 pixels, each, and two filled silicon bolometer arrays with 16 x 32 and 32 x 64 pixels, respectively, to perform integral-field spectroscopy and imaging photometry in the 60-210 mu m wavelength regime. In photometry mode, it simultaneously images two bands, 60-85 mu m or 85-125 mu m and 125-210 mu m, over a field of view of similar to 1.75' x 3.5', with close to Nyquist beam sampling in each band. In spectroscopy mode, it images a field of 47 '' x 47 '', resolved into 5 x 5 pixels, with an instantaneous spectral coverage of similar to 1500 km s(-1) and a spectral resolution of similar to 175 km s(-1). We summarise the design of the instrument, describe observing modes, calibration, and data analysis methods, and present our current assessment of the in-orbit performance of the instrument based on the performance verification tests. PACS is fully operational, and the achieved performance is close to or better than the pre-launch predictions.
