Science Goals Improve statistical constraints on dark energy –2x improvement for SNLS, Essence, SNAP Improve systematics uncertainties on dark energy –Better calibration of SN properties –Span wide range of physical & empirical parameters –Constrain SN physics 300 Type Ia SNe –in the nearby smooth Hubble flow –with many-epoch spectrophotometry

SNAP - Simulated Hubble Diagram

Few SNAP SNe

SNfactory Operations Budget LBNL Physics Division –$500k for CCD cameras & electronics –$150k/yr for UH telescope –$XXk/yr for postdocs, students, travel, etc. LBNL HST/NASA –$220k for HST UV spectral analysis and search operations IN2P3 (LPNHE+IPNK+CRAL) –1.7MEuro for SNIFS hardware & technical manpower –SNIFS interventions –$XXk/yr for postdocs, students, travel, etc. Yale NSF –$??M for camera hardware & technical manpower –$40k for SNIFS second red dewar –XXk/yr for camera operations –XXk/yr for postdocs, students, travel, etc. Chicago - Kavli Institute –$40k calibration hardware –$XXk/yr for postdoc. students, travel, etc.

SNfactory Budget - Moore Grant Moore grant is $2.4M USD over three years Intent is to enhance usefulness of SNfactory database Not intended to fund existing operations Funding for 3 postdocs and 2 software engineers Deliverables: –Spectral database w/ full traceability –Scheduler
