Cause Identification of Beam Losses in PETRA III by Time Correlation of Alarms

PETRA III is a high brilliant synchrotron light-source operating at 6 GeV at the DESY site in Hamburg. The Machine Protection System (MPS) of PETRA III is under operation since the beginning of the commissioning of PETRA III in April 2009. Under certain alarm conditions the MPS generates a dump command and protects the machine against damage. As a functional extension the MPS hardware examines the time correlation of alarm sequences after a beam loss. The alarm sequences are evaluated in a software based system so that the cause of a beam loss can be displayed in the control room immediately. This paper describes the hardware implementation as well as the software rules.
