Automatic Component Calibration and Error Diagnostics for Model-Based Accelerator Control

摘要

Phase I work studied the feasibility of developing software for automatic component calibration and error correction in beamline optics models. A prototype application was developed that corrects quadrupole field strength errors in beamline models. This application uses a decompositional approach, first analyzing the beamline to identify good and bad regions within the model, then correcting each bad region individually. This application deploys a new method for localized error correction that is described in this report. Phase I work also studied the heuristics necessary for successful use of this component calibration methodology. This study established the need for intelligent heuristics in the area of data filtering, data interpretation, and search. A full system for automated component calibration will need to provide customization options so that users can specify the particular heuristics needed to handle a given data set and problem configuration. A method for assuring maximal flexibility and customizability is to provide the necessary functionality in the form of a general toolkit and function library for building model-based applications. Initial analysis was begun on the design of such a toolkit.
