3. 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/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

4. 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

5. 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 OSHA, NFPA and BNL Safety Requirements. • Meet BNL Radiological Control Requirements. • Meet Suffolk County Article 12 Drinking Water Standard.

17. Magnet Monitor Cost Example • From MS Project (Direct Costs): • Materials from Cost Book: • Labor is Engineering Judgment D. Phillips RSVP Preliminary Baseline Review

18. 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.

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 purchased complete with HVAC, Fire Alarm System, Power & Lights. • Labor is engineering judgment.
