HEP Strategic Plan
The DOE HEP program, with input from the scientific community (HEPAP), is pursuing a long-range plan that
maintains a leadership role for the U.S. at the three scientific frontiers that define the field.
The major elements of this plan are to:
enable U.S. leadership roles in the Tevatron and LHC
programs at the Energy Frontier
achieve the vision of a world-leading U.S. neutrino
and rare decay program at the Intensity Frontier,
building on
the existing accelerator infrastructure at Fermilab
deploy selected, high-impact experiments at the
Cosmic Frontier
support accelerator R&D to position the U.S. to be at
the forefront of advanced technologies for next-
generation facilities.
maintain a strong, productive university and
laboratory research community
Lays out what the nation will get with different investments
Scenario A (FY 2008 Approp + COL) – unable to mount world-class programs at all three frontiers
Scenario B (FY 2007 Approp + COL) – productive programs at all three frontiers
Scenario C (FY 2007 ACI level) – leadership programs – partner in TeV-scale facility
Scenario D (additional above C) – the funding to host next TeV-scale facility

U.S. Intensity Frontier Program
The HEPAP envisioned “world-class” intensity frontier program entails evolution of the Fermilab accelerator complex
– MINOS/Minerva NOvA (700kW) LBNE (700kW) SLBNE (2000 kW)\
– The accelerator infrastructure allow: SLBNE neutrino factory muon collidier (regain the Energy Frontier)
Envisioned “world-class” intensity frontier program also entails development of an underground detector
– LBNE need a large underground detector (~100-300 ktons)
– A large detector (~300 kton) at the right depth (~5000 ft) detector can also do proton decay
– Physics goals: searches for CP violation and proton decay at factors of 10-100 greater sensitivity
Goals are ambitious and will take significant combined (DOE, NSF, other countries) resources
– NSF is proposing a Deep Underground Science and Engineering Laboratory (DUSEL)
– Europeans have a large underground detector in their strategic planning
– Japanese are also interested in the science
DOE and NSF have had discussion with OMB and OSTP on how to coordinate planning
– NSF is supporting the preliminary design of the DUSEL facility and a suite of experiments
– DOE HEP has CD-0 approval for the LBNE that includes the neutrino beam and a large underground detector
– DOE and NSF are working together to coordinate their efforts, avoid duplication, and optimize their investments
– DOE Undersecretary Koonin and NSF Director Bement submitted to OMB a joint statement indicating support
Intensity Frontier:
Other Activities
Other Intensity Frontier “scientific opportunities”
HEP has received a report from SLAC describing possible US options in SuperB (Italy)
– Three possible scenarios (both minimal and optimal)
1. Provision of reusable PEP-II and BABAR components
2. 1 + additional funding for US participation in detector program
3. 2 + additional funding for US participation in accelerator program
HEP expects to get a proposal for participation in Belle-II at SuperKEKB (Japan)
– Participation in detector subsystems
HEP expects to get a proposal for implementing the g-2 experiment at Fermilab
– Utilizes existing Fermilab infrastructure and planned upgrades (and BNL D&D)
HEP will conduct peer-reviews of these “scientific opportunities”

– ESA has indicated interest in a partnership on their proposed dark energy mission
– NASA and ESA are studying the possibilities of such a partnership
DOE and NSF charged HEPAP to assess opportunities in particle astrophysics
– HEPAP [Particle Astrophysics Scientific Assessment Group (PASAG)] Report was submitted in 2009
– Guidance is being utilized in DOE SC HEP planning
Looking for guidance from Astro2010 - the findings and recommendations:
– Will influence the opportunities for HEP participation
– Will inform OHEP on scientific/technical aspects of particle astrophysics
(e.g.; optimum dark energy strategy with available resources)
OECD Global Science Forum Astroparticle Physics Working Group
– Global coordination and planning of astroparticle physics experiments
– Study report will be completed in Oct. 2010

Guidance
HEPAP (PASAG) Report
Optimized program over the next 10 years in 4 funding scenarios:
• Similar to P5 funding Scenarios
Prioritization Criteria for Particle Astrophysics
• Science addressed by the project necessary (significant step towards HEP goals)
• Particle physicist participation necessary (significant value added/feasibility)
• Scale matters (particularly at boundary between particle physics and astrophysics)
Priorities are generally aligned with recommendations for Cosmic Frontier in the 2008 HEPAP (P5) Report
• Dark matter & dark energy both remain high priorities
Guidance:
• Dark energy funding (recommended for largest budget portion) should not significantly compromise US
leadership in dark matter, where a discovery could be imminent
• Dark energy and dark matter together should not completely zero out other important activities
• HEP (along with NASA and NSF) awaits Astro2010 Report before decisions on proposed major projects (AGIS,
Auger-North, BigBOSS, JDEM, LSST).

Significant activities and issues
U.S. leadership in Accelerator R&D
Historically the U.S. has been a leader in the development of advanced accelerators
The developments have been largely driven by the HEP program, and supported by the DOE HEP, in the quest
for higher energies and intensities and more demanding beam properties.
U.S. leadership in this area is being challenged by efforts in other regions and countries
– Investments have been made and are being made in new forefront HEP accelerator facilities
– There appears to be recognition by governments of the importance of accelerator competency and infrastructure
– Industrial capabilities have been nurtured in Europe/Japan and are now preferred vendors for specialized
accelerator components
HEP has begun to address this technology gap
– Started in FY 2007 to nurture the development critical accelerator capabilities (e.g.; SRF cavities) in the U.S.
– Participating in the international ILC and muon collider effort R&D effort
– Significant Recovery Act funding directed towards accelerator R&D and in particular industrialization
HEP sponsored an Accelerator R&D Workshop in 2009
– to make a more direct connection between fundamental accelerator technology and applications
– To obtain guidance on the needs of federal programs and the private sector
– Report is expected soon
21
U.S. HEP program
at a crossroad
U.S. has not made investments in onshore HEP research capabilities
Number of U.S. accelerator user facilities has been reduced to one
Investments have not implemented a sustainable U.S. program
– Major investment over last decade has been offshore (LHC)
– Proposed onshore initiatives have not materialized (BTeV, ILC,.…)
Foreign nations have made (are planning to make) investments in HEP research capabilities
Europe CERN/LHC (Phase I &II) Energy Frontier
Japan J-PARC / S- BELLE neutrinos /rare decay/ e+-e- collider
China BES-II / Daya Bay electron beams / neutrinos
Italy (Super-B) e+-e- collider
If the U.S. wants to remain among the leaders investments need to be made
A realistic strategic plan has been developed that will position the U.S. to play a leadership role
– Develop research infrastructure in the U.S. that produces outstanding science and a technology foundation
– Provides a role for U.S. scientists in campaigns at all three scientific frontiers
– Positions the U.S. for a productive, sustainable program in the future
Leadership in HEP is important to the Nation
– Delivers new knowledge/discoveries about the world we live in - that have significant impact on other scientific fields
– Attracts and trains a next generation of scientists for the Nation’s scientific workforce
– Develops advanced technologies that are important for the Nation’s security and competitiveness

A Plan that will deliver new
technologies and scientists for the Nation
The accelerator and detector technologies developed for high energy physics
research in the past have had important impacts on the Nation’s economy,
security, and society. (See http://www.science.doe.gov/hep/benefits/index.shtml)
– Sciences: Many of the tools developed for particle physics have led to important
scientific innovations, such as the synchrotron light source, that benefit other
areas of science.
– Medicine: Accelerators and detector technologies first developed for particle
physics are now used throughout the nation to treat and diagnose patients
– Homeland security Similarly, detector technologies have found uses in cargo
scanning and monitoring of nuclear waste and proliferation
– Computing: To record and analyze the unprecedented volumes of data generated
in particle collisions, particle physicists have developed cutting-edge computing
technologies, including the www and grid strategies
An important benefit to the Nation provided by the OHEP program is the
recruitment and training of a highly motivated, highly trained scientific and
technical work force.
– About 80% of those completing doctoral degrees in particle physics or accelerator
science ultimately pursue careers in outside high energy physics research: i.e.;
• industry, national defense, information technology, medical instrumentation,
electronics, communications, biophysics, etc.
