Predict intensity and losses based on historical data, apply ALARA constraints, calculate resulting throughput, and iterate for new predictions. Explore machine evolution for potential gains beyond historical models. This study is based on intensity measurements over the last decade and focuses on AGS injection improvements and control measures.

Intensity Development – MECO Performance Predictions/Limitations based on History and present plan (6Jan05 ahrens)
Summary • Predict intensity and losses from history based model • Apply ALARA constraints • Calculate resulting throughput • Evolve the machine and iterate -> new throughput • Gives a prediction of potential gains – where it is useful to look for improvement
Model • Model based on intensity measurements taken over the last decade (C-A/AP/86 10/02 Zeno) • Realistic with modest intensity • Optimistic at highest intensities – linear transfer function, no high intensity roll off • Performance “beyond the model” requires new ideas and development time
One of Several Plots from the Zeno note – the basis for the model
Evolution • Historic machine • AGS injection improvements (MECO) • Booster acceleration loss control (ALARA) • Booster injection loss control (ALARA) • Booster acceleration eff (no ALARA) • everything
