Abstract:
Magnet power supplies are critical components of a storage
ring. The performance of power supplies directly impacts the
stability and reliability of the storage ring operation.
There are several kinds of DC power supplies in Duke FEL
Storage ring. The performance data of power supplies can be
collected in an non-interruptive manner by an EPICS archiver
or by a matlab program. Matlab based tools have been
developed to analyze the power supply data collected during
the operation. Careful evaluation of data allows us to
locate a power supply with degraded performance and perform
preventative maintenance.
