The University of Wisconsin Astronomy Department and the Space Astronomy Lab at UW are designing an SHS spectrometer for the WIYN 3.5-meter telescope on Kitt Peak and the SALT 10-meter telescope in South Africa. The new device will be mated to the Sparsepak, (Bershady et al, 2004, 2005) and/or the Hydra fiber array at WIYN, and fed by either the prime focus image at SALT or the High Resolution Spectrograph fiber-feed at SALT. The spectrograph will produce spectra at a reciprocal dispersion, R = 25,000 in 20 orders, each order covering an average wavelength band 250 km/s wide, for a total wavelength range of 5000 km/s. Spectra from approximately 82 fibers will be resolved. Once the system is proven at WIYN, and because the aperture size for this spectrometer does not scale with telescope size, we will be able to test this same prototype at the SALT 10-meter telescope. This will be the first application of this technique to large aperture astronomical observations.
