  1. Making Projections Stretch Optimistic Conservative AAC Review, May 10th, 2004 - Prebys

  2. Reasons for Optimism • We have begun to use the collimators in normal operation: Losses w/o collimators RF Region Losses with collimators AAC Review, May 10th, 2004 - Prebys

  3. Effect of Collimators on Activation • One week of collimator operation…. • Difference from previous week measurement (mr/hr @ 1ft) AAC Review, May 10th, 2004 - Prebys

  4. Protons to MiniBooNE • Rather than use the instantaneous rate, will scale from typical weekly MiniBooNE totals: • Baseline Scenario: • Improvements compensate for increased protons to pBar -> Continue to average 5.5E18/wk • MBooNE shuts OFF 1/05 • Optimistic Scenario: • MBooNE rate increases more or less linearly to 10E18/wk at 1/05 • 5.5E18/wk after NuMI turns on. • Stretch Scenario: • MBooNE rate increases linearly to 10E18/wk at 1/05 • 5.5E18/wk after NuMI turns on. • Linearly to 10E18/wk on 1/06 Typically 5.5E18/wk AAC Review, May 10th, 2004 - Prebys

  5. Protons to MiniBooNE AAC Review, May 10th, 2004 - Prebys
