Paper Abstract

TIMMI is the ESO Infrared camera dedicated to 10 micrometers high angular resolution imaging of the austral sky. This camera, built for the European Southern Observatory (ESO) by the Service d'Astrophysique at Saclay (SAp), has been successfully commissioned during 2 observing runs at the ESO 3.6-m telescope: one in July 1992 and the other in January 1993. Based on a LIR 64*64 pixel Si:Ga/DVR detector array optimized for ground-based broad-band 10-micrometers astronomical observations, the camera, operated at a frame rate of 120 Hz, has achieved a noise equivalent flux density of 0.01 Jy min-1/2 pixel-1 (1 (sigma) ) during N2-band observations with a pixel field of view of 0.48 arcsec. Two other fields of view are available: 0.32 and 0.65 arcsec. A filter wheel allows to select between 14 broad-band and narrow-band filters covering the atmospheric window (8 - 13 micrometers ); a M filter allows observations in the 4 micrometers atmospheric window with substantial sensitivity. The instrument is now available to visiting astronomers.
