Paper Abstract

In the last few years, we have undertaken a number of studies and experiments to assess the impact of various environmental factors on the performance of the ESO very large telescope interferometer (VLTI). The investigated topics include atmospheric turbulence, wind loads on the telescope structure, vibrations created by equipment, natural thermal variation, thermal load from electronics, natural and man-made seismic noise, as well as acoustic noise. A first report of this activity was given in a previous paper. This paper presents the final results obtained in 1995. The main outcome is the very good confidence that the VLT 8 m telescope and the infrastructure design is adequate for interferometric use at optical wavelengths down to the visible.
