Plan is based on High Energy Physics Advisory Panel “P5” report from 2008.
Progress in achieving the goals of particle physics requires advancements at the
HEP at its core is an accelerator-based experimental science.
*Does not include reductions for 0.2% rescission, $16M contractor pay freeze, and unobligated Prior Year funds
FY 2010 appropriation including SBIR/STTR was $810 million, so the FY 2012 request is a reduction of $13 million from FY 2010.
Scenario B (FY07 + COL)
Scenario A (FY08 + COL)
Ramp up ILC, SRF, and some accounting changes.
Trading projects for more research
only extending the run if new funding could be found.

MINOS FAR DETECTOR
DOE and NSF had developed a partnership model for the physics program at the deep Underground Science and Engineering Lab (DUSEL), which would be in the Homestake Mine in Lead, South Dakota.

On May 1, the SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS) released the largest and most detailed three-dimensional map of the distant universe, constructed using 14,000 quasars as backlights to explore large scale structure in the universe at the APS meeting in Anaheim
BOSS has demonstrated that this technique works with their first year of data and expect to be able to make the first measurement of the expansion history of the Universe at redshift z>2 when they collect their full sample of 160,000 quasars.

The green area is the Lyman alpha forest region where BOSS detects theabsorption of quasar light corresponding to the presence of hydrogen, whichacts as a tracer of the matter distribution. Luminous Red Galaxies are used as al tracer at low redshift (also shown).

Astro2010 made recommendations to DOE as part of a ground/space-based Dark Energy program.
Dark Matter (direct detection)
High Energy Particles
Auger, FGST, VERITAS – operating
Bill Atwood (SLAC UCSC) and Peter Michelson (Stanford) and the FGST/LAT team won the 2011 Bruno Rossi Prize in Astrophysics for enabling, through the development of the Large Area Telescope, new insights into neutron stars, supernova remnants, cosmic rays, binary systems, active galactic nuclei and gamma-ray bursts.
Cosmic Microwave Background:
There is a decrease in project funding as DES and SuperCDMS complete. HAWC starts fabrication in FY12. LSST and dark matter experiments are in an R&D phase before starting MIEs.
Oct. 2009 - Received guidance from HEPAP (PASAG)
Recommended an optimized program over the next 10 years in 4 funding scenarios
Defined Prioritization Criteria for Contributions to Particle Astrophysics Projects
Dark matter & dark energy remain the highest priorities
Dark energy funding shouldn’t compromise US leadership in dark matter
Should not completely zero out other activities; HAWC and VERITAS-upgrade recommended in any funding scenario
August 2010 - Received guidance from Astro2010
Recommendations to DOE as part of a coordinated ground/space-based Dark Energy program:
The optimistic (doubling) funding profile allows investment in:
LSST – DOE should partner with NSF
WFIRST – DOE should contribute
At lower funding level:
LSST is recommended as the priority because DOE role is critical
Other identified opportunities:
2nd priority ground based - contributions to NSF mid-scale experiments
e.g. BigBOSS, CMB, HAWC experiments, etc.
4th priority ground-based - NSF & DOE contribute as a minor partner to a European-led CTA ground-based gamma-ray observatory
Oct. 2010 - OECD Global Science Forum Astroparticle Physics Working Group
A 2-year study of global coordination and planning of astro-particle physics experiments
recommended annual agency-level meeting to coordinate program (starting Spring 2011)
The Cosmic Frontier
Our current projections tend towards the lower funding amounts
Do not have the same profile as assumed by Astro2010.
DOE OHEP Objectives:
Contributions to select, high impact experiments with discovery potential
that address particle-astrophysics goals
where DOE HEP researchers and investments can play a significant role in and make significant contributions (PASAG recommended criteria)
Achieve earliest, best, and most cost-effective U.S. dark energy and dark matter science results
Partnerships with NASA and NSF and international collaborators as appropriate
Dark matter – direct detection experiments are a priority (not part of Astro2010 study)
Maintain a leading U.S. role in dark energy research (Astro2010 recommendation)
Other opportunities for contribution as funding permits
