A Time-interval-based event matching method for asynchronous data streams
摘要
Purpose
In experiments with multiple detectors, independent data acquisition systems may share a common external trigger signal and produce asynchronous data streams. This paper presents a method for identifying and aligning corresponding events across the data streams with their own timestamps for offline data analysis.
MethodsThe method is based on the time intervals between consecutive events to match events.
ResultsValidation using beam test data demonstrates a high matching efficiency of 99.37%.
ConclusionThe method provides a reliable and robust solution for offline event matching in independent data acquisitions sharing a common external trigger signal.
