METHODS, MEDIUMS, AND SYSTEMS FOR IDENTIFYING TUNABLE DOMAINS FOR ION BEAM SHAPE MATCHING

Techniques for adjusting the shape of an ion beam are described. Characteristics of a desired beam shape may be defined. The ion beam generator may include beam shaping elements associated with tunable parameters that can be set in combination with each other. A search space for the possible combinations is defined. A set of exploratory points in the search space are measured and used to interpolate a large number of interpolated points based on a regression model. Interpolated points that are associated with low confidence values may be measured. Based on the measured and interpolated points, clusters of tunable parameter combinations may be identified for evaluation. The clusters are evaluated for stability and sensitivity, and one of the clusters is selected based on the evaluation. The ion beam generator may be configured based on the selected cluster.
