PACS - A Photodetector Array Camera & Spectrometer for Herschel|
The PACS is one of three science instruments
for ESA's Herschel Space Observatory (HSO, formerly known as FIRST).
It operates either as an imaging photometer or an integral field spectrometer over the spectral band from 57 to 210 Ám.
- Simultaneous two-band (same field of view) 60-85 Ám or 85-130 Ám and 130-210 Ám imaging
- Two filled bolometer arrays: 32x16 and 64x32 pixels
- Point source sensitivity: ~3 mJy (5-sigma limit in 1 hour)
PACS is being designed and built by a consortium of institutes and university departments from across Europe under the leadership of Principal Investigator Albrecht
Poglitsch located at Max-Planck-Institute for Extraterrestrial Physics,
- Simultaneous 57-105 Ám and 105-210 Ám spectroscopy
- 47"x47" (5x5 pixels) field-of-view rearranged via an image slicer on
two 16x25 Ge:Ga detector arrays
- Sensitivity: ~5x10^-18 W/m^2 (5-sigma in 1 hour)
Consortium members are:
Austria: UVIE; Belgium: IMEC, KUL, CSL; France: CEA, OAMP; Germany: MPE, MPIA; Italy: IFSI, OAP/OAT, OAA/CAISMI, LENS, SISSA; Spain: IAC.
Principal Investigator: Albrect
Poglitsch, Max-Planck-Institut fur Extraterrestrische Physik.
Co-Principal Investigators: Christoffel Waelkens, KU Leuven, Belgium.
Instrument Control Center: PACS-ICC -
operational nerve center and Project Office site at the PI institute in Garching, Germany.
