Session 54 - Ground and Instrumentation Techniques and Catalogs.
Display session, Wednesday, June 12
A new very high resolution cross-dispersed echelle spectrograph has been tested at the Starfire Optical Range 1.5 m telescope. It takes advantage of the diffraction limited images provided by adaptive optics to achieve a resolving power of R \sim 250,000 together with a wavelength coverage in a single exposure of about 300 Åabout 100 times that of conventional very high resolution spectrographs. This was achieved by recording 60 cross dispersed orders across the 18\times 18 mm^2 format CCD detector. The total efficiency of the CCD based system, including the sky and telescope transmission, spectrograph and detector, is measured to peak at 1.3%.
