Strategy of the improved experiment

• More muons E821 was statistics limited
  sstat 0.46 ppm, ssyst 0.3 ppm
• Backward-decay, higher-transmission beamline
• New, open-end inflector
• Upgrade detectors, electronics, DAQ
• Improve knowledge of magnetic field B
• Improve calibration, field monitoring and
  measurement
• Reduce systematic errors on ?a
• Improve the electronics and detectors
• New parallel integration method of analysis

5
Schedule (as presented to PAC in 04)

• FY 2005
• RD as funding permits
• FY 2006-2007
• Construction
• FY 2008
• Fall, pulse on demand, debugging
• Spring, 3 week engineering run
• FY 2009
• 2100 hours data collection
• (26 weeks _at_ 80 hr/wk)

6
New Hardware and Other Tasks

• Beamline
• New front-end magnets Quads Dipoles
• BNL Responsibility (Wuzheng Meng)
• Beamline simulations
• BNL Responsibility (Phil Pile?) with help from U.
  Illinois
• Inflector
• New inflector with open ends
• Japanese (Tokin) have agreed to make it, all they
  need is / (Wuzheng Meng and Akira Yamamoto)
• Storage Ring Magnet
• Needs to be put back in operating order
• BNL Responsibility
• Vacuum System
• Needs to be put back in operating order
• BNL Responsibility (Dick Hseuh)

7
New Hardware ctd. -2

• Quadrupoles
• Need to be put back into working order
• BNL Responsibility (Yannis Semertzidis)
• Kicker
• Needs modifications to lower inductance and
  increase peak current
• Kicker 1s failure needs to be understood
• BNL Responsibilities (Arlene Zhang? D. Warburton,
  J. Mi? BLR)
• Proper GEANT-based Tracking Program
• Boston Responsibility

8
New Hardware ctd. -3

• CBO damping system
• RF Dipole
• (or)
• Pulsed Octupole
• Needs simulations, engineering design
• Responsibility to be determined, but BNL at
  present (Oxford???)
• Precision Magnetic Field
• New calibration probe
• Better field monitoring and control
• Better shimming
• University Collaborators Responsibility

9
New Hardware ctd. -4

• Detectors
• New electron calorimeters
• University Collaborators Responsibility
• Front-end Electronics
• New WFDs
• University Collaborators Responsibility

10
Collaboration Resources

• Boston University Scientific Instrument Facility
  (underutilized at present)
• Resources
• 7 full-time machinists
• State of the art CNC machining capabilities
• High Vacuum Welding Capabilities
• Collaborative Rate 35/hr
• We produced 1M of parts for E821 _at_
  30 - 35/hr plus materials
• We expect to use this resource for E969.
• We can make pole pieces for new beamline magnets,
  vacuum chamber or kicker parts, etc.

11
Collaboration Resources

• Boston University Electronics Design Facility
• Resources
• 3 full-time engineers
• State of the art electronics design capabilities
• University of Illinois Nuclear Physics Laboratory
• Resources
• Two mechanical technicians
• Machine shop facilities comparable to BU

12
Modified Schedule

• FY 2006
• P5 Approval
• RD as funding permits
• FY 2007-2008
• Finish RD
• Construction
• FY 2009
• Fall, pulse on demand, debugging
• Spring, 3 week engineering run
• FY 2010
• 2100 hours data collection
• (26 weeks _at_ 80 hr/wk)

13
Summary

• We would hope for first beam in 2009
• Production run in 2010
• The Collaboration is ready to go full speed ahead
  if we get approval next spring
