Overview • Overview of Work to Date. • Project Definition Reports • Current Building Concept • Requirements • Costs • Issues • Summary Mu2e Working Group May 19, 2010
8 GeV Booster Project Definition Reports for September 2008 and May 2009 located in Doc DB #357. Sites that extracted beam at AP 60 were studied. Site near AP 20 at same location as the original P-Bar source tune up beam. Alt. 2 Site AP 20 ANTIPROTON SOURCE AP 60 GIESSE ROAD Study Site Alt. 1 Site Mu2e Working Group May 19, 2010
Alt. One Siting • Beam Extracted at AP-60 routed west. • Deep Beamline to transverse Indian Creek • Potential Wetland Issues • Disturb woods adjacent to creek Mu2e Working Group May 19, 2010
Alt. One Site Plan • Services Routed from Main Injector/Mini BooNe • Greenfield site • Beamline interrupted by Indian Creek Mu2e Working Group May 19, 2010
Alt. One Detector Hall Plan Mu2e Working Group May 19, 2010
Alt One Summary • Detector situated under crane, massive amount of shielding blocks used for 21 Feet of Cosmic Shielding • Construction estimated at 18 months • Loaded Construction cost estimated at $41 Mil • 30% Contingency • Risks included: • Wetlands / Flood Plain • Programmatic Requirements • Subsurface Characteristics Mu2e Working Group May 19, 2010

Beamline • Purpose: To house beamline equipment that transports beam from AntiProton Source to Production Solenoid. • 8’ wide x 8 ‘ high enclosure.(256 meters long) Constructed on cast-in-place concrete base slab using cut and cover excavation methods. • 21’ Shielding (not confirmed) • Personnel egress via stairs at each end; equipment access via shielded hatch • Location for Power Supplies not yet determined; may require a Service Building. Mu2e Working Group May 21, 2010
Requirements / Specifications • Requirements / Specifications are acquired from the Project Team via: • Weekly Tech Board Meetings • Weekly Conventional Coordination Meetings • Bi-weekly Beamline Meetings • There is still a lot of work to develop a credible CDR. We will need to have either firm specifications or agreed upon placeholders by mid August to complete the scope drawings, system designs, cost estimate and schedule. This seems probable from the discussions so far. • Requirements document in progress. Mu2e Working Group May 19, 2010
Environmental / Life Safety • The Conventional Construction aspects of the project is expected to conform to an existing CX. • A RFP for environmental investigation and delineation of the wetlands along Indian Creek has been issued. • If for some other reason (like beam energy) an EA is required then the Conventional Facilities will need to address all environmental impacts. • Initial review with Life Safety Consultant, SchirmerEngineering. Need to firm up elevations before formal review. • ODH mitigation discussed, will be developed with cryo and solenoid design. • Primary Beam Shielding Mu2e Working Group May 19, 2010
Other L2 Management Docs • Preliminary Risk Registry • WBS • Integral Project Team Mu2e Working Group May 19, 2010
Costs • Costs appear to be moving in upwards direction from the May 2009 PDR. Mu2e Working Group May 19, 2010
Cost Breakdown Mu2e Working Group May 19, 2010
Issues • Buildings “Architectural Significance” • Road Patterns • Beam Shutdown Construction “if we produced a dowdy site with shabby buildings, then the technical people we wanted to work with us would not come and the statesmen, who might judge us in part by appearances, would not, in the long run, give us the funds we would need for our physics.”“Starting Fermilab”, Robert Rathbun Wilson, 1992 Mu2e Working Group May 19, 2010
Summary • A concept for the design of the Detector Hall has been developed. • The type of construction is typical at Fermilab. Low to medium risks are anticipated. • No known significant environmental risks. • Project Team providing requirements and feedback on overall design; system specific criteria development needed.
