The interstellar medium on the line of sight toward gamma Cassiopeiae was observed in the 950-1150 Angstroms region at a resolving power of ~ 200,000 by the Interstellar Medium Absorption Profile Spectrograph (IMAPS) as part of the ORFEUS-SPAS space shuttle flight in September 1993. The gamma Cas sightline was previously studied with the Copernicus satellite (see Ferlet et al. 1980, ApJ, 242, 576) where a four-component structure was derived (VLSR = -24.6, -17.1, -7.8, 1.3 km/sec). However, at the Copernicus resolution of 15 km/sec this velocity structure was somewhat uncertain and several ambiguities remain. With the higher resolution of IMAPS ( ~ 2 km/sec) it is now possible to address some of the longstanding questions about the complex velocity structure of this sightline. This paper presents an analysis of several atomic lines (e.g. C II 1036-37, N I 1134-35, N II 1084-85, Ar I 1048, 1066, P II 1124, 1152) and lines of the H_2 Lyman bands. The velocity structure and column densities are compared with the Copernicus results.
