The Antimatter Problem

• Big Bang started with equal parts matter and
  antimatter
• Now there is only matter? Where did the
  imbalance come from?

Strategies for Studying the Universe

• Accelerator experiments We create particles that
  have not existed since the first moments after
  the Big Bang
• We study how they behave and interact
• Tools are particle accelerators and detectors
• Astrophysical observation We observe the relics
  of the big bang
• Observe the Universe as it exists today
• Tools are observatories in space and on the
  ground
• The two ends of our investigation must meet

SLAC Particle Physics Future

• Successful completion of B-Factory Program
• Accelerator based research at the energy frontier
• ILC, LCD, ATLAS, LARP, Accelerator Research
• Investigations of Dark Matter and Dark Energy
  (non-accelerator)
• GLAST, LSST, JDEM
• Understanding the fundamental nature of the
  neutrino
• EXO
• All elements supported by strong program of
  theoretical investigations

11
B-Factory Physics Program

• Operations through Sept 30, 2008
• Data analysis and continue for several more years
• Open scientific questions will remain!
• There are surprises yet to come!

12
Evolution of B-Factory Accelerator Resources

• SLAC will operate worlds first x-ray laser
  starting in FY2009
• Uses 1/3 of SLAC linac
• ASD will operate LCLSmajor function for ASD
  start-ing in 2009
• ILC is growing
• Some ASD resources will naturally evolve there
• SABER will start independent operations in late
  2009

13
The Energy Frontier LHC

• SLAC Participation in LHC
• Participation in LHC Accelerator Research Program
  (LARP)
• Designing collimators for LHC/LHC Upgrades
• Participation in beam commissioning of
  accelerator
• SLAC physicists have joined ATLAS
• Participation off to good start
• Attracting excellent postdocs and students
• SLAC will host Tier 2 computing center for LHC
• Partnering with UCSC and LBNL will have very
  strong west coast hub for ATLAS community
• LHC opens an exciting new energy frontier for
  particle physics
• Optimistic (with good reasons) that there will be
  lots of exciting new physics there

14
The Energy Frontier ILC

• The highest priority for the international field
  of particle physics is the full, direct
  exploration of the TeV energy scale.
• with high probability new physics will be there
• ILC an essential tool in this exploration
• SLAC is committed to the ILC
• SLAC staff are broadly involved in all elements
  aspects of the ILC effort
• Playing critical roles
• Presidents FY07 budget very encouraging for the
  field!
• Tremendous help from EPP2010

15
The Energy Frontier Accelerator Research
SABER

• Accelerator Research for Future Machines
• High Gradient Studies for CLIC type machine
• Development of L-band power sources for ILC
• Proof of Principle Studies of New Acceleration
  Mechanisms

Neutrinos -- EXO

• Determining the fundamental nature of neutrino
• Search for bb0n decay in 136Xe--gt136Ba e- e-
• Absolute mass scale?
• Is the neutrino its own antiparticle?

20
Planning for FY09 Transition

• In FY09 the B-factory will stop operations LCLS
  will start operations
• The challenge we face between now and 2009 is the
  balance of the B-factory priorities with LCLS
• We recognize this challenge and it is being
  actively and aggressively managed
• Transition planning well underway
• TWG led by PSD and Keith Hodgson
• Laboratory will grow between now and end of the
  decade

Safety

• Thank you for your focus and attention to safety
• Thank you for effectively integrating safety into
  the planning and execution of your work
• Safety is an individual responsibility of each of
  us here at SLAC
