Summarydata
Event data
Relevant experiment and machine properties, which allow to draw an operational decision and to make post analysis of long term processes.
It’s a machine and experiment protection module in order to keep components safe and to provide pure experiment.
Operational description of the experiment
Definition of abnormal, unforeseen and observable situations, when the full data set is needed in order to study them later.
