Figure 21
Tenth-percentile local momentum acceptance contours from ensemble evaluation of 117 error ensembles with random and systematic multipole errors. The level of systematic multipoles was varied between 0.03% and 0.3% of the main harmonic at a radius of 10 mm, for each multipole. In order to conserve computing resources, computations were peformed for the first four sectors only. Tests indicate that this is sufficient to characterize performance. |
