– SDO, GLAST, LIGO, EXO… - ~$40M (2007)– NeXT, IRIS in recent SMEX (NASA)– Grants - ~$3M– ~11/20 postdocs, ~16/30 students

* Campus support– Half teaching faculty salary, ~1 postdoc, ~8/30 student GTA, administration– Start up, Enterprise fund, Bridging

* Private support – FKB ($11M), PAB (~$30M), Schwob (~$1M)– Kavli-Hewlett endowment (->$15-20M over 10 years)

• First two Kavli Fellows advertised this summer

– Simonyi ($20M), Gates ($10M), Schmidt ($1.5M), Keck($1.5M) for LSST– Agilent support of CMB research– Computational hardware (multiple)


P5 Report to HEPAP

* Cosmic Frontier Recommendations– Support for the study of dark matter and dark

energy as an integral part of the US particle physics program.

– DOE support the space-based Joint Dark Energy Mission, in collaboration with NASA, at an appropriate level negotiated with NASA.

– DOE support for the ground-based Large Synoptic Survey Telescope program in coordination with NSF at a level that depends on the overall program budget.

– Joint NSF and DOE support for direct dark matter search experiments.

– Limited R&D funding for other particle astrophysics projects and recommends establishing a Particle Astrophysics Science Advisory Group.


Non-Accelerator Program

GLAST: Overview

* GeV Gamma-ray Large Area Space Telescope– Successor to EGRET telescope on CGRO- ~109 photons from ~104 high energy cosmic sources over ~10 yr.- Seek dark matter annihilation signal– Stanford leads Large Area Telescope - major instrument– Original design by Atwood (1993) – Successful inter-agency, international collaboration– Project cost $690M [$90M foreign contribution, $45M DOE]– NASA will contribute $25M MO&DA

* June 11 launch; uniformly nominal performance– “Nominal” operation so far– Efficient cosmic ray (104/) removal– Observing already– First light release Early August

* Instrument Science Operations Center (ISOC) @ SLAC– ~$4M/14 FTE

Simulated LAT (>1 GeV, 1 yr)


LSST: Overview

* Large Synoptic Survey Telescope (orig. DMT 1995) * Dark matter/energy using weak gravitational lensing

– Test of FCDM is now an issue of physics– Supernovae, BAO, strong lensing, ancillary science

* NSF-DOE-Private Collaboration– SLAC $3M/9FTE– Simonyi-Gates $30M, Schmidt $1.5M, Keck $1.5M

* Mirror cast; grinding begins in August– Site selection in Chile

* SLAC leads the (3 GPx) camera collaboration;16 institutions* SLAC also working on database (~100PB)

– Discussions with ASCR, industry, private

* NSF CoDR(2007); NSF PDR + DOE CD1 2009?, ASTRO2010* First light 2016
