  3. Significant Issues • Antiproton Source service building shielding • Antiproton Source service building space • Costs higher than expected • Human Resources S. Werkema

  4. Service Building Shielding • Shielding design criteria: • < 1 mRem/yr to public at 175 m (considered negligible). • Need an overall reduction factor of >500 relative to the existing shielding.* • Shielding Cap: additional ~160X • (from MARS simulations in progress) • Require additional factor of 4 to 5 from: interlocked detectors, eberm, or long detectors (Total Loss Monitors) • *Assumes total beam loss of 2%. Shielding Cap Original Service Building Work in progress: MARS simulations to calculate shielding factors are in progress FNAL Accelerator and ES&H personnel are studying the possible use of eberms and TLMs at Fermilab S. Werkema

  5. Service Building Space • Service building space requirements are still being compiled • g-2 service building space requirements not known • Need more space in AP30 and AP50 Some of the equipment that will be required for the Accumulator injection kicker. Not shown: Fluorinert skid, electronics racks. S. Werkema

  6. High Costs • Much work on BOEs remains. Total Accelerator Systems cost is not yet known. • Total will be much higher than Accelerator + Target estimate for the Mu2e proposal ($21.74M includes base & contingency) • Having difficulty determining what went into this estimate • Several big ticket items with costs greater than expected: kicker magnets, pulsed power supplies, beam absorbers, RF, extraction septum, PS heat & radiation shield • Likely service building expansion or construction S. Werkema

  7. Personnel Issues • Received temporary engineering support from AD/ME, AD/EE, AD/Instrumentation, and Tech. Div. for BOEs • Big effort – much accomplished • Work still in progress • The issue of long term mechanical and electrical engineering support remains • Radiation Safety level 3 manager (Tony Leveling) is over committed (Pbar Target station, JASMIN, Mu2e) • Many AD people associated with Mu2e are still primarily working on Collider Run II • Possible loss of one level 3 manager in coming months S. Werkema

  8. New People Gerry Annala (AD/TeV) • Help Carol Johnstone with external beamline • Coordinate overall accelerator mechanicals systems development (cooling, vacuum, magnet stands, etc.) Curtis Baffes (AD/ ME Support) • Target station integration engineer Ron Moore (AD/TeV) • Assistant Division Head/Coordination of Mu2e and g-2 S. Werkema

  9. What’s Going on Now • Big effort to finish BOEs • Several changes must be made to the CDR • MARS simulations for service building shielding studies • Planning for beam studies that need to be done before the beam goes off in September. • Trying not to think about g-2 • Run II (complete on September 30) S. Werkema
