Paper Abstract

The Adaptively Corrected Echelle Spectrograph (ACES) high resolution echelle spectrograph was originally developed at Steward Observatory to couple adaptively-corrected stellar images to the instrument using a near single mode optical fiber to give R~190,000 at V band. We explore here the feasibility of using the spectrograph with the 2x8.4m Large Binocular Telescope (LBT), preserving the fiber coupling for instrument isolation and illumination stability, but employing either a narrow slit or image slicer to offset the smaller component size and thereby preserve high resolution. Such a combination could offer simultaneously higher resolution with greater wavelength coverage per exposure than the configuration of alternate instruments.
