In contrast to commonly used scaler-based approaches where events at a certain sample frequency are counted, we present a measurement concept resolving single event detector timestamps in the sub-ns regime leveraging a well established off-the-shelf TDC VMEbus module. This allows for high resolution time structure information with respect to the ring RF as well as valuation of inter-particle separation distributions. This yields insightful information for specific experiments at GSI whose efficiencies are heavily limited by pile-ups and detector dead times. We will present the concept of the measurement setup and exemplary data taken in recent campaigns in context of spill microstructure improvements for slow extraction.
