  1. RSVPAGS Upgrade Projects1.4.4 MECO RSVP Preliminary Baseline Review Brookhaven National Lab April 6-8, 2005 D. Phillips

  2. MECO Cost Burdened FY05 $’s D. Phillips RSVP Preliminary Baseline Review

  3. Construction Requirements • Transport Proton Beam from AGS to Proton Target. • Provide for installation of RF Modulated Magnet and Extinction Measurement Equipment. • Provide MECO Experimental and Solenoid System Infrastructure. • Meet All Safety Requirements. • Meet BNL Radiological Control Requirements. • Meet Suffolk County Article 12 Drinking Water Standard. D. Phillips RSVP Preliminary Baseline Review

  4. AGS Beam Specifications • MECO AGS Beam Specifications: • Momentum = 7.5 GeV/c • Spill length = 0.5 sec • Rep rate = 1.0 sec • Intensity • Experiment goal = Two bunches/AGS cycle 20TP/bunch • AGS base-line (achievable) = 20 TP/0.5sec spill (1 spill/sec) • Time between bunches = 1350 nsec • Beam bunch width = 30 nsec full width • Extinction between bunches = 1E-9 • Beam hours: • engineering run = 800 hours • physics run • 2800 hours at 40 TP/spill (stretch goal) • 5600 hours at 20 TP/spill (base plan) • total integrated protons for physics run = 4.0E20 • Caveat = run time will depend on achievable muon flux, actual background rates etc.. D. Phillips RSVP Preliminary Baseline Review

  5. Targeting Requirements • Muon Yield: The target must be compact and have minimal material around it to avoid reabsorbing pions from the primary interaction before they produce muons. • Extinction: The dimension of the target transverse to the beam should be small to minimize the phase space for protons intercepting the target after receiving less than the maximal kick in the RFMM • Beam Spot: the preceding requirements imply a small (sradius1 mm) beam spot in order to keep ~95% of the beam on the target • Aperture Limits: The beam must pass through the complex region of the PS – TS interface. The area available for the beam is limited. Particularly as shielding is needed to protect the coils from beam fault conditions. • Adjustability: the field in the MECO solenoids can be reversed for calibration studies, but the beam must still strike the target. The downstream beam steering magnets must accommodate the difference in incoming trajectory needed for this. D. Phillips RSVP Preliminary Baseline Review

  11. MECO Schedule D. Phillips RSVP Preliminary Baseline Review

  12. 1.4.4 MECO Work 15 FTEs/Quarter 10 FTEs/Quarter 5 FTEs/Quarter D. Phillips RSVP Preliminary Baseline Review

  13. 1.4.4 MECO Cost $95k Rigging $103k Royals $87k Cable Burdened FY05 $’s $172k LN2 Tank Purchase Moving to 1.5 $372k Shielding Purchase D. Phillips RSVP Preliminary Baseline Review

  14. Major Milestones • A-Line Ready for MECO Beam Tests – 10/1/07 • Ready for Beam Tests in FY08 • Design Review of A-Target Area – 1/15/09 • Major functional & ALARA concerns • A-Line Ready for Solenoid Installation – 4/1/08 • Allows Solenoid Systems installation to begin • A-Line Ready for Beam to MECO – 6/1/11 • WBS 1.4.4 MECO is complete D. Phillips RSVP Preliminary Baseline Review

  15. Low Level Milestone - Magnets D. Phillips RSVP Preliminary Baseline Review

  16. Refurbish Magnets Cost Example • From MS Project (Direct Costs): • Magnet Materials – From cost book: • Mechanical $1050 • Electrical $303 • Not all magnets need all parts, engineering judgment use $1000/magnet • Labor is engineering judgment from experience refurbishing magnets D. Phillips RSVP Preliminary Baseline Review

  17. Shielding Installation Cost Estimate • 1.4.4.2.7.1.2.8 Install Cosmic Ray Roof – Contingency: • Technical – 2 Minor Mod to existing design • Tec Weight – 2 Design • Cost – 4 In-house estimate based on similar experience • Cost Weight – 1 Labor • Schedule – 8 Delays completion of MECO Construction • Design – 8 Conceptual Design phase • Total Contingency is 24% D. Phillips RSVP Preliminary Baseline Review

  18. Build Final Layout Cost Estimate Cosmic Ray Roof 30ea 34’ Roof Beams Cosmic Ray Side Wall 80 Blocks Cosmic Ray Zinc 35 Blocks Temp Dump 180 Blocks Install Beam Dump 160 Blocks Remove Roof 72 Roof Beams Modify Side Wall 300 Blocks Replace Roof 192 Roof Beams D. Phillips RSVP Preliminary Baseline Review

  19. Electronics Hut Cost Estimate • From MS Project (Direct Costs): • Building Purchase based on 3/04 quote for a similar building ($99,250/480 sq ft = $210/sq ft) Building specified complete with HVAC, Fire Alarm System, Power & Lights. • Labor is engineering judgment.
