LSA/FiDeL2 Work package 1/2 Generate Calibration CurvesGenerate Calibration Curves Implement FiDeL alogorithms in JAVA under LSA Database model - FiDeL coefficients. Develop application to drive calibration curve generation, regeneration etc. Provide application to populate FiDeL coefficients Test Generate harmonicsGenerate harmonics LSA parameter space/database configuration Implement FiDeL in JAVA under LSA Populate harmonic coefficients where required. Extend above application for generation/re-generation Use in settings generation. bn compensation with corrector circuits. Test & cross-check

LSA/FiDeL3 Work package Decay & SnapbackDecay & Snapback Implement FiDeL in JAVA/LSA Develop trim engine for injection plateau How to get powering history? Strategy? Extend application to allow input, generation, re-generation, display etc. HistoryHistory DC powering history (as above). Correctors & some quads - intra-fill history - how to track this when required? Export results to MADExport results to MAD Utility to extract harmonics at any point in given LHC cycle.
