Overview Overview of Work to Date. ◦ Project Definition Reports Current Building Concept Requirements Costs Issues Summary Mu2e Working Group May 19, 20102

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. Mu2e Working Group May 19, ANTIPROTON SOURCE 8 GeV Booster AP 60 AP 20 Alt. 2 Site GIESSE ROAD Alt. 1 Site Study Site

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.

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,

Environmental / Life Safety 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, Schirmer Engineering. Need to firm up elevations before formal review. ODH mitigation discussed, will be developed with cryo and solenoid design.

Issues Buildings “Architectural Significance” Road Patterns Beam Shutdown Construction Mu2e Working Group May 19, “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

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. Mu2e Working Group May 19,
