Building Strong National and International
Collaborations

• Every LBNL physics program is built on
  collaboration with university groups and other
  national labs.
• In ATLAS, SNAP, Daya Bay, and DUSEL, LBNL has
  provided major leadership from the outset.
• In each, we plan to continue playing a central
  role throughout the program.

DOE-HEP Mission Statement

• The mission of the High Energy Physics (HEP)
  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.

Cosmology is a central part of HEP.

Particle Astrophysics and Cosmology a
Grassroots Movement

• Numerous efforts initiated by university and lab
  groups
• SCP, GLAST, SDSS, SDSSII
• DES, BOSS, SNAP, LSST
• DOE-supported discovery of dark energy is among
  the major achievements of our field.
• Dark energy is the biggest challenge in
  fundamental physics.

SNAP measure expansion history and growth of
large-scale structure.

• Must measure both to distinguish dark energy from
  failure of General Relativity.
• Space mission required to reduce systematics.
• SNAP builds on our pioneering program on
  supernova (SNe Ia) cosmology.
• A weak-lensing survey complements the SNe Ia to
  optimize program as shown by DETF.
• Anticipated DOE share of JDEM is 400M.

SNAP RD Achievements
New compact telescope optics concept proved
exceptional performance in a rocket-borne
experiment (key to JDEM). Founded on LBNL and UCB
strong optics heritage from Keck.
LBNL HEP IC group developed readout of high
channel-count cryogenic pixel plane.
Powerful collaboration of universities and labs
with industry resulted in high QE out to 1.7 ? in
4M pixel format. Now detector of choice for
other JDEM proposals.
12M-pixel LBNL CCD with high QE out to 1.0 ? and
low diffusion is radiation resistant. Same
technology is baseline for LSST detectors.

Part of SDSS-III, BOSS uses redshifts of 1.6M
galaxies (z0.5)and Lyman-? forest of 0.16 M
quasars (z2.5) to determine cosmological
parameters.
SDSS telescope at Apache Point
Sloan Foundation agreed to support SDSS-III.
Proposals pending at DOE and NSF. MOUs signed or
in negotiations with many institutions

Replace red CCDs on SDSS camera with
w/red-sensitive LBNL/SNAP CCDs, making it
possible to go to higher-z

Cosmology Views

• We cant be satisfied with understanding 5 of
  the Universe both dark energy and dark matter
  are fundamental experimental issues for the
  field.
• DOE has led the exploration of dark energy and
  has several important Stage III experiments,
  including DES and BOSS.
• The US is currently the world leader in dark
  energy research. SNAP will ensure that DOE
  retains this leadership position.

16
LBNL and ATLAS

• Our highest-priority accelerator-based program.
• LBNL a leader in ATLAS since 1994.

LHC Views

• Our view maintenance/operations and
  software/computing support too low for US
  scientists to fully exploit investment in ATLAS.
• Modest increase (15) needed.
• Very strong support of detector upgrades
  essential to maintain US leadership at energy
  frontier at CERN.
• Support advanced technology contributions to LHC
  machine upgrades.

DUSEL opportunities

• Provides ultimate neutrino oscillation program.
• Site for direct detection of dark matter
  (Sadoulet et al.).
• Site for future neutrinoless double beta decay
  (LBNL double beta decay efforts in CUORE and
  independent initiative by Nygren).
• Natural connection with Kevin Lesko in Nuclear
  Science Division.

27
Program Summary

• SNAP anchors our cosmology program and is the
  crucial next step in the exploration of dark
  energy.
• ATLAS and LARP remain the primary foci of our
  accelerator-based program.
• The Daya Bay measurement will help define the
  future of neutrino physics.

28
Views Summary

• Strong support of the U.S. LHC program, including
  machine and detector upgrades, is essential if
  the U.S. is to retain its role at the energy
  frontier.
• Dark energy is the biggest challenge in physical
  science! SNAP will provide the most important
  step forward.
• Neutrinos least understood part of the Standard
  Model. Daya Bay likely to provide next big clue.
  
• Long-term RD needed.
• Detector RD.
• High-field magnet development.
• Accelerator RD.
