Williams report recommended priorities

• For the team
• Focus resources on exploiting beamline 12.2.2.
• Establish the ALS as the premier facility for
  powder diffraction from laser heated samples in
  diamond anvil cells with an emphasis on
  usability.
• Once this is completed start development of a
  single crystal facility.
• For the project manager
• Acquire a high-pressure gas loading apparatus.
• Expand the staff.

15
We should fully implement the Williams report
recommendations
16
Focus on bl12.2.2

• Reduce support of 1.4 and 11.3 to 10 for
  July-Dec 07 period
• Reduce support of 1.4 and 11.3 to 0 from January
  08

Fiber lasers
18
Improve laser heating

• New fiber lasers move current laser to HPlab
  for development system
• Move microscopes and micro-drills to a new
  microscope lab
• Utilize optics skills within LBNL
• Form a development task force
• Model existing system and proposed improved
  systems
• Rebalance skills in the HP team bring in more
  optics and laser skills
• Build optimized system

Aim to deliver before fall AGU
