Multi-object high-resolution echellette spectroscopy with IMACS
2003
INSTRUMENT DESIGN AND PERFORMANCE FOR OPTICAL/INFRARED GROUND-BASED TELESCOPES, PTS 1-3
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 11000Angstrom 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.
