Abstract
A powerful high resolution spectrometer has been developed, and is installed at the Coude Focus of ESO's 3.6 m telescope. It can also be fed by a 1.4 m auxiliary telescope dedicated to the instrument. With this latter telescope magnitude 10 stars can be observed at a resolving power of 100.000 and with a good instrumental profile. The CES also features a single channel scanner mode which can attain a resolving power of 300.000 with an extremely high spectral purity.
