Paper Abstract

By adding a prism-cross-dispersed echellette grating as an optional module to the Inamori Magellan Areal Camera and Spectrograph (IMACS), complete spectra from 3400 to 11000Å of 15 simultaneous objects may be achieved with a resolution of R = 21,000 for a projected 0.5-arcsec slit width and a 5.0-arcsec slit length. The additional cost of this module is on the order of $50,000. This echellette module (IMACS-E) is intended for studies of stellar abundances where the targets are sufficiently dense over the 15 arcmin IMACS field of view to take advantage of the multi-slit capability. Such applications include the study of Galactic bulge stars, stars in local group galaxies, stars in Galactic globular and open clusters, and the integrated light of extra-galactic globular cluster systems.
