The University of Texas McDonald Observatory will build a high-                 resolution spectrograph of novel design incorporating a large                   echelle grating and prism cross dispersion.  Spectra will be                    projected onto the largest Charge Coupled Device (CCD) image                    detector available -- the new Tektronix TK2048M.  This 55-mm                    square solid state silicon image detector will produce over 4                   million picture elements per exposure.  With this combination the               entire spectrum of an astronomical object between the atmospheric               ultraviolet (UV) cutoff and the near-infrared (IR) limit of CCD                 sensitivity will be acquired simultaneously at high resolution.  A              1-hour exposure will obtain spectra of stars at V magnitude 11                  with signal-to-noise 100, while useful spectra can be obtained to               magnitude 15 in 3 hours.                                                                                                                                        Major motivations for the new instrumentation are its ability to                gather quickly and completely spectra needed to determine CNO,                  (Carbon, Nitrogen, and Oxygen) abundances in cluster stars and                  magnesium (Mg) isotopic abundances in old metal-poor dwarfs, stars              that are fainter than current limits for these studies.  The                    search for planets around nearby bright stars will rely on the                  high radial velocity precision enabled by the statistics of large               numbers of simultaneously-measured spectral line profiles to                    determine small periodic motions in the parent star induced by                  orbital motion of the planet.
