  1. LSST Program and Development Status Kirk Gilmore SLAC/KIPAC/LSST SLAC Annual Program Review

  2. Development of the LSST concept LSST is motivated by massively parallel astrophysics to answer a wide range of today’s pressing questions in cosmology and fundamental physics Astronomy “LSST: From Science Drivers to Reference Design to anticipated Data Products” Ivezic et. al. 2008 Astro-ph: 0805.2366 Endorsed by several NAS panels and reports on astronomy and high energy physics 2000-2002 Community Committee Developed “Towards the LSST Design Reference Mission” Strauss et. al. 2004 LSST Science Requirements Document LSST Science Council www.lsst.org 2006 LSST Physics LSST probes 100x fainter & enables the exploration of the time domain. SLAC Annual Program Review

  3. LSST Science Requirements focus on 4 Representative and Divergent Programs Dark Energy-Dark Matter Exploring our Solar System LSST enables multiple investigations into our understanding of the universe LSST will find 90% of hazardous NEOs down to 140 m in 10 yrs “Movie” of the Universe: time domain Mapping the Milky Way Discovering the transient and unknown on multiple time scales LSST will map the rich and complex structure of our Galaxy. SLAC Annual Program Review

  4. Key LSST HEP Mission: Dark Energy Precision measurements of all four dark energy signatures in a single data set. Separately measure geometry and growth of dark matter structure vs cosmic time. • Weak gravitational lensing correlations (multiple lensing probes!) • Baryon acoustic oscillations • Counts of dark matter clusters • Supernovae to redshift 0.8 (complementary to JDEM) • Probe anisotropy! LSST unique SLAC Annual Program Review

  5. LSST has submitted an NSF proposal for $242 M of Construction funding Construction proposal submitted in February 2007 60 Month Construction and Commissioning Ready for MREFC Funds in FY2010 - Expect in FY 2011 Proposed as Public Private Partnership to Share costs NSF MREFC - $242 M DOE HEP - $50 M Private - $100 M Current Design and Development NSF 4yr Award = $14.2 M DOE Lab Participation Partner In-Kind Private Donation Operations and Maintenance Summit, Base, Archive, Data Centers = $45 M/yr (2016) (FY06 $ with Contingency) SLAC Annual Program Review

  15. Major camera risk mitigation scheduled prior to construction are buying down risk SLAC Annual Program Review

  16. -50V -10V BNL and sensor group are providing leadship for schedule driven sensor development • Request for proposals for prototype science CCDs • issued Feb. 2008 • contract award June/July 2008 • 5 high-resistivity, thick CCDs from study program have been extensively characterized • design models validated • behavior of dark current, quantum efficiency, and point spread function vs. thickness, temperature, and electric field • flatness and surface morphology • antireflection coating • CCD controllers for 4 new test labs under construction • UC Davis, SLAC, Paris, Purdue • allows full-speed testing of segmented sensors • Components for CCD/electronics chain testing in assembly (Raft/Tower electronics: prototype by end of year X-ray images SLAC Annual Program Review

  17. Specs RFP for Prototyping Filters in 08 Half-Maximum Transmission Wavelength • 75 cm dia. • Curved surface • Filter is concentric about the chief ray so that all portions of the filter see the same angle of incidence range, 14.2º to 23.6º • Filter RFP being sent out to selected vendors • Filter prototyping will qualify vendors to fabricate science filters SLAC Annual Program Review

  18. Contamination test chamber at SLAC Other major efforts using SLAC resources Camera Controls Main Chamber MAIN FORE Working is proceeding on plans to deliver a prototype test stand by end of calendar year 2008 - Goal by PDR Fore or Preparation Chamber cold finger SLAC Annual Program Review

  19. Conclusions • LSST Camera R&D progressing well toward NSF full LSST PDR, scheduled for early 2009. • A contemporaneous DOE CD-1 would keep the project on track to enable first light in 2016. • Significant growth in this program is envisioned beginning if FY10, with LSST replacing GLAST as the major development effort in particle astrophysics and cosmology at SLAC.
