Paper Abstract

The Echelle spectrograph FOCES,1 that was operated at the 2.2m Calar Alto telescope between 1995 and 2009 was moved to the laboratories of Munich University Observatories and is being as a test bed for a number of different stability issues related to high precision radial velocity spectroscopy. We utilize FOCES to study spectrograph stability, illumination stability and fiber transport stability. Results from temperature and pressure stabilization are presented with this paper. We will show, that we reach the requirements set by our model analysis approach presented in [2]. Peak to valley mid term stability of temperature and pressure is as good as 0.002K and 0.02hPa.
