We propose to find and follow ~ 200 Type Ia supernovae with the Mosaic Imager on the Blanco 4-m telescope over a five-year period. The Gemini part of this proposal is to provide the critical spectroscopic classifications of the SNe Ia. The search is designed to find supernovae distributed evenly over the redshift range [0.15, 0.75]. We aim to answer a simple, but very important, question: is the dark energy of the universe consistent with a cosmological constant (w=-1)? If not, this means the dark energy must be a more general energy field such as ``quintessence.'' The proposed spectra will sort the SNe Ia from the other SNe, hypernovae, and AGN activity, and we will be able to measure accurate supernova rates as a function of lookback time to almost half the age of the universe. For some core-collapse SNe, we will be able to derive distances through the expanding photosphere method, a critical cross- check for the distance methods. The classifications will be announced immediately to allow other teams to monitor the supernovae discovered by the survey.
