abstract = {PETRA-III is a 3rd generation synchrotron light source
dedicated to users at 14 beam lines with 30 instruments. The
storage ring is presently modified to add 12 beam lines.
PETRA III was operated with several filling modes such as
40, 60, 480 and 960 bunches with a total current of 100 mA
at electron beam energy of 6 GeV. The horizontal beam
emittance is 1 nmrad while a coupling of $1\%$ amounts to a
vertical emittance of 10 pmrad. During a user run the
Machine Protection System (MPS) may trigger an unscheduled
beam dump if transients in the current of magnet power
supplies are detected which are above permissible limits.
The trigger of MPS stops the ring buffers of the 226 BPM
electronics where the last 16384 turns just before the dump
are stored. These data and transient recorder data of Magnet
Power Supply Controllers are available for a post-mortem
analysis. Here we discuss in detail the functionality of a
Java GUI used to investigate the transient behavior of the
differences between set and readout values of different
power supplies to find out the responsible power supply that
might have led to emittance growth, fluctuations in orbits
or beam dumps seen in a post-mortem analysis.},
