GENIE is the Ground based European Nulling Interferometry Experiment. To be built by ESA as technology demonstrator for DARWIN and to become a full facility instrument for ESO's VLTI. The current preliminary design of GENIE concentrates on a two-way beam combiner operating in the (near-) infrared (K, L, or N band). The science objective of GENIE is to observe a couple of hundred candidate stars for DARWIN in order to measure the zodiacal light and bright orbiting extra-solar planets. Kick-off for GENIE was in June 2002, and the instrument is scheduled for commissioning in 2006. GENIE will be built by industry with support of academia.
We provide results of the readings of the four temperature/humidity HMT 323/HMP 303 sensors installed in the VLTI laboratory on Paranal in Sep 2004 within the GENIE T/RH sensor project as PostScript and raw ASCII files.
