2. Outline Introduction Controlling the Storage Ring with MATLAB Integrating Diagnostics Tools: Automating Tune Measurements The Future Summary KIT – The cooperation of Forschungszentrum Karlsruhe GmbH and Universität Karlsruhe (TH)

3. ANKA Synchrotron Radiation Source Storage ring: 2.5 GeV 110 m circumfence Low Alpha mode: 1.3 GeV Coherent THz radiation KIT – The cooperation of Forschungszentrum Karlsruhe GmbH and Universität Karlsruhe (TH)

4. ANKA Control System Based on ACS (ALMA common software) Java frontend CORBA for intersystem communication Backend components: Power supplies BPMs etc. ACS manager ACS components (backend) ACS clients (frontend) KIT – The cooperation of Forschungszentrum Karlsruhe GmbH and Universität Karlsruhe (TH)

5. Why Connect ACS and MATLAB ACS contains all information about the current state of the storage ring Beam Position Monitors (BPMs) Magnet currents RF frequency MATLAB is a great tool for simulations and measurements Accelerator Toolbox LOCO (Linear Optics from Closed Orbits) Combining both allows for live fitting of the model to the “real” storage ring KIT – The cooperation of Forschungszentrum Karlsruhe GmbH and Universität Karlsruhe (TH)

12. The Future: Integrated High-Level Interface to the Control System KIT – The cooperation of Forschungszentrum Karlsruhe GmbH and Universität Karlsruhe (TH)

13. Summary A software bridge for controlling the storage ring from MATLAB has been created Tune and chromaticity measurements have been automated, thus reducing the workload on the operator / accelerator physicist A common abstraction layer, centralizing access to the machine model, the control system and diagnostic tools is planned KIT – The cooperation of Forschungszentrum Karlsruhe GmbH and Universität Karlsruhe (TH)
