MECi Project

• MECi Project Scope
• Deliver tailored FEL photon beam into a target
  chamber located in the FEH Hutch 6
• Spacial profile, intensity, spectrum, repetition
  rate
• Produce laser system necessary for High Energy
  Density Science
• Long pulse for driving shocks, higher energy
  (100sJ)-low rep rate, lower energy (10sJ)-higher
  rep rate
• Short pulse, as much energy as possible
• Provide suite of target diagnostics to allow
  Users to attain data
• Surface motion phase shift, measure
  x-ray-XUV-visible spectra
• Provide machine control systems and DAQ for
  diagnostics, laser, and end station systems
• Optics diagnostics controls, laser controls

MECI Risks

• Risks/Mitigation
• ARRA/Stimulus funding issues
• Long procurement process foreign procurements-
  meeting with ARRA core working group to formulate
  plans
• Ensure procurement duration is built into
  schedule
• Use Advanced Procurement Plans
• Scope cost increases (TPC already defined)
• Identify areas of scope contingency
• May limit target diagnostics procurement until
  later in project
• Manage scope to maintain 30 contingency
• Establish bottoms-up cost asap
• Staff availability
• Complete RLS and review with LCLS
• Potentially limited by project funding

24
MECI Risks

• Risks/Mitigation
• Lusi is big sister to MEC
• MEC has large reliance on LUSI designs
  performance
• MEC has running start on beamline, however..
