         Overview and Strategic Plan
                   for the
  Fermilab Center for Particle Astrophysics

                DOE/OHEP Mission


The mission of the High Energy Physics program is
to understand how our universe works at its most
fundamental level. We do this by discovering the
most elementary constituents of matter and
energy, exploring the basic nature of space and
time itself, and probing the interactions between
them.

      Imprint of new primordial quantum fields on large
         scale matter and radiation today
 Dark Energy
      Apparent acceleration of cosmic expansion
 Dark Matter
      What is most of the mass in the universe?
 High energy particles

FNAL role in the larger particle astrophysics community

 Fermilab enables large projects with substantial
  university participation
    Examples include SDSS, DES, CDMS, COUPP, Auger,…
    Lab engineering and technical base vital
    Project management and interface to DOE
 Fermilab facilitates R&D
    Facilities and technical personnel allow for generic
     detector R&D (e.g. bubble chambers, liquid argon, solid
     Xenon, CCDs,…)
    Lab scientist and engineering base allow internal review
     process as projects materialize from detector R&D
    New ideas can be generated either within FNAL or from
     users (mainly from the university community)




                                                                                  9

                                Evolving Program

 On-going programs in Dark Energy (DES), Dark Matter
  (CDMS, COUPP), High Energy Particles (PAO South) and
  Theory will continue to cover the Frontier
    Will remain the core Particle Astrophysics program
 Other initiatives ready to start: depend on proposal,
  review to get non-scientist funding
    Dark Matter (next generation CDMS,COUPP, LAr)
    Planck scale unification (Holometer)
    CMB (QUIET-II)
 FCPA also explores new ideas
    Need to shape new activities beyond ~2015 as DES ends
    Most will not ever become fully realized
    Often driven by younger people (Wilson Fellows, postdocs)

                                                                                     10

                         PASAG recommendations
   “In all budget scenarios, the Xenon100 upgrade, the LUX350
    detector, an effort on DAr, funding for the MiniCLEAN
    detector, the additional towers in SuperCDMS Soudan, the
    COUPP 500 construction, the 100-kg SuperCDMS- SNOLAB
    experiment and the phase II upgrade to ADMX are supported.”
 We are positioned to become the world’s leading DM lab

   “PASAG recommends that QUIET II be supported at the
    proposed scope under all budget scenarios.”
 In all budget scenarios, new FNAL role in CMB is supported

   “Auger North addresses questions of great interest (namely the
    origin of the highest energy particles) using an established
    technique that builds on the success of Auger South. Given its
    relative science priority for HEP and the funding constraints,
    PASAG recommends significant HEP support for the construction
    of Auger North in budget Scenarios C and D.”
   Great physics, but may have to wait for improved funding
                                                                                    11
    Particle Astrophysics at Fermilab-- November 2009-- Craig Hogan and Dan Bauer
      New projects outside scope of PASAG review


 Holometer, GammeV, CHASE, GRIM REPR:
        – “nonaccelerator beams”: laser cavities as new tools
          for fundamental physics
        – New fundamental physics up to Planck scale
        – Where “Cosmic Frontier” intersects with others

 Proposals to be submitted
        – Starts with modest scale experiments
        – Holometer is next step
        – PAC will hear more about new axion searches at the
          next meeting (CHASE, GRIM REPR)



                                                                                  12
  Particle Astrophysics at Fermilab-- November 2009-- Craig Hogan and Dan Bauer
                          Plan for New Projects

 Expand Dark Matter experiments now
    Depends on funding of expansion proposals
    Major thrust now recommended by PASAG
 Add new program in holography, axion physics now
    Reviews and proposals this fall/winter
 Add CMB now
    Final outcome depends on NSF QUIET-II proposal
 Develop other options for future
      PASAG noncommital on Dark Energy projects
      JDEM still an option, but scope of SOC is in doubt
      21 cm? LSST? BigBOSS?
      DUSEL DM?
      PAO North?
      Solid Xe? CCD DM?

                                                                                  13

 FCPA coordinates KA13, astro parts of KA14,15
      Align with agency; frequent phone meetings
      Align with Directorate
      Division budget/effort reconciliation: challenges in
       allocating Division resources


   KA 13 01 02 = Scientists
   KA 13 01 03 = Projects
   KA 14 01 02 = Theory (including astro theory)

       FY2010 Budget: Problems with DOE FIN plan

 Main issue in current budget: ~$1.1M shortfall in
  particle astro scientist (“base”) funding
      Needs fixing before we can move forward on anything
      If it is not fixed, need to shrink scientist participation
      Forfeit our leading position to respond to PASAG
      Even established core programs are at risk
      True shortfall is bigger by 365K, covered by carryover
      How do we make sure the scientists are covered?




                                                                                  20
