MECO Goals, Organization, and Funding

• Michael Hebert
• UC Irvine
• GA Kickoff Meeting
• November 13, 2002

2
The RSVP Project

• Two experiments on Rare Symmetry Violating
  Processes (RSVP) have been combined to form a
  single NSF Major Research Equipment and
  Facilities Construction (MREFC) program
• KOPIO seeks to understand better the reason
  that the Universe contains only matter, rather
  than a mixture of matter and anti-matter.
• MECO Muon to Electron Conversion - seeks to
  understand why there exist two extra copies of
  particles that make up the matter around us.
• Both experiments are being conducted in the
  Alternating Gradient Synchrotron at Brookhaven
  National Lab on similar time scales
• The two experiments are organized as independent
  entities, coupled only at the NSF Program level

3
MECO Organization and Goals

• Two separate, if largely overlapping,
  organizations working closely together
• MECO Collaboration
• Goal Conduct the experiment and analyze the
  results to yield a four order of magnitude
  improvement in sensitivity to m N ? e N
• Led by MECO Spokesperson Bill Molzon
• Defines the scope of the project including
  baseline cost, schedule, and performance goals
• MECO Project
• Goal Construct the experiment to meet the
  performance requirements within the established
  baseline cost and schedule
• Led by MECO Project Manager Mike Hebert

The Solenoids and This Study

• The solenoids are both the cost drivers and
  critical path system for the project
• The latter motivates preparation of a bid package
  ASAP to be ready to go as soon as construction
  funding is available
• The GA study forms an important part of that
  package, providing additional input about
  reliable and cost - efficient construction
  techniques as well as optimized cost and schedule
  estimates for those processes.
• The results of this study will be incorporated
  into the Technical Specifications and vendor
  Statement of Work that will be included in the
  RFP package
• Note that MECO will hold confidential any Vendor
  Proprietary construction processes.

Magnet Design Management Group

• The MDMG began as the oversight group for the CDR
  effort and continues to assist the Subsystem
  Manager with oversight of the magnet procurement,
  final design, and construction
• Chaired by Solenoids Subsystem Manager Brad
  Smith (MIT)
• A MECO physicist to address the detailed physics
  requirements of the solenoid system Bill Molzon
  (UCI)
• A BNL engineer to address interface,
  installation, and operational issues for the
  system on the AGS floor Mike Iarocci (BNL)
• Advisory Members
• MECO Project Manager Mike Hebert (UCI)
• BNL AGS Liaison Engineer for MECO D. Phillips
  (BNL)
• BNL AGS Liaison Physicist for MECO W. Meng
  (BNL)
• Brad will be the point of contact for the GA
  effort, although including the other two members
  on communications would help keep everyone up to
  date

• Despite concerted political efforts, RSVP does
  not appear to be in the FY03 Congressional
  appropriations for the MREFC program
• We hope to be in the Presidents FY04 budget to
  be released next February
• In the meantime we are moving forward on the most
  critical tasks with a combination of NSF RD
  funds and DOE support for some collaborating
  groups

Wrapping Up

• Contract Status
• All required UCI approvals have been obtained and
  the contract has been forwarded to NSF
• The NSF program office acknowledges that it has
  all of the information required for approval
• We expect them to approve the contract and
  forward it to their Grants people shortly, but we
  have no definite start date as yet
• We hope to hear from them later this week
• For additional information about MECO visit our
  web site at http//meco.ps.uci.edu
• We are looking forward to working with you to
  optimize the manufacturing aspects of the system!
