SNS diagnostic design review process

• Standard Process of Diagnostic Development
• Preliminary Design Review
• Respond to committee observations and suggestions
• Final design review
• Respond to committee observations and suggestions
• Laser-wire Diagnostic System
• The Laser-wire results have been presented at the
  final design review of LANL but not reviewed as
  the baseline diagnostic.
• We have incorporated the suggestions made at the
  one and half days of workshop held SLAC.
• We have tested the Laser-wire at BNL and LBL and
  hope to test the prototype at FNAL.
• We seek your advice today on the proposed
  development of a laser wire design for SCL. We
  will certainly address your comments in our final
  implementation.

Request to the ad hoc committee

• Evaluate Laser wire proposal
• We seek your advice on the following
• Assumptions
• Relevant calculations
• Options considered
• Interface requirements
• Manufacturing/ Procurement plan
• Have the right analyses/ tests been done?
• Are there any holes that need to be addressed?
• The SNS diagnostic group will consider
  committees feedback.
• The SNS diagnostic group partners will respond to
  the committees comments
