Cycle configuration Cycle Configuration Element cycle depends on

Cycle configuration Cycle Configuration Element cycle depends on: • Cycle code (Energy, Intensity) • Beam optics settings (e. g. Tune, Chromaticity) Cycle execution Beam diagnostic Optics computations Optics determined with: • Mad-X • Own routines • Procedures PP-110627 -a-MHA 1 Markus Hager

RMS has the following data stored in its database: • • • Cycle codes Timing event definition Timing sequence of the cycles Optical length and position of the machine elements Transfer functions of the magnets BL(I) Waveforms and setpoints for the cycles in integrated magnet field values RMS generates the control values for the power supplies: BL(t), BL(I) -> I(t) PP-110627 -a-MHA 7 Markus Hager

Status What do we have so far? Ideas and first documents: • Controls: Cycle Configuration Workflow, Optics Connector Design (Mad-X and API) • Physics: Mad-X usage, Cycle Configuration, Physics Library What is missing? • • • Cycle Configurator design, Interface definitions (e. g. interfaces to RMs) Clarification of many, many details User interface PR-110627 -a-MHA 8 Markus Hager
