Our group at the University of Washington is currently working to upgrade the optical spectroscopic capabilities of the Astrophysical Research Consortium (ARC) 3.5-meter telescope at Apache Point Observatory (APO) in New Mexico. The first part of this project involves modifying the KOSMOS spectrograph. The Kitt Peak National Observatory Ohio State Multi-Object Spectrograph (KOSMOS) is a spectrograph originally built for the Kitt Peak National Observatory (KPNO) through a collaboration between Ohio State University (OSU) and the National Optical Astronomy Observatory (NOAO). It is now being modified and moved to the APO 3.5-m. KOSMOS is a longslit instrument that improves efficiency and brings the possibility for multi-object capabilities across 360-1000 nm. Upgrades are being made that will provide slit viewing, as well as possibilities for internal calibration. The multiple configurations of slits, filters, and grisms make KOSMOS versatile instrument for the wide range of science interests in the ARC collaboration. In this poster, we present the current status of modifications and characterization of KOSMOS.
