Application of model-independent analysis using the sdds toolkit

The model-independent analysis (MIA) method in accelerators has not yet come into widespread use, unfortunately. This is perhaps due to a lack of convenient tools to bring the measurement data to the results stage. At the Advanced Photon Source, we used the SDDS toolkit and the SDDS-compliant EPICS toolkit in simple and not-so-simple applications for diagnosing operational problems from beginning to end in a short time. We were able to make quantitative measurements of pulsed power supply noise and beam position monitor noise, and identify an unstable power supply
