Abstract

SNAP supernova measurements rely on acquiring high quality samples of well identified type Ia supernovae. This requires a dedicated and optimized spectrograph. We propose an innovative concept for an integral field spectrograph for the SNAP observatory. Spectra obtained with this instrument will be used to identify Type Ia supernovae discovered by SNAP, and will play an important role in the planned systematic studies. A very compact design with various configurations based on prisms and/or gratings is under evaluation by the IN2P3 and INSU institutes in France. The expected performance of the most efficient configuration that meets the scientific objectives will be presented.
