Timing Synchronization in the Nab Experiment's DAQ System

The Nab experiment seeks to determine the electron–neutrino correlation coefficient `a' and the Fierz interference term `b' in free neutron beta decay, offering high-precision tests of the Standard Model and sensitivity to potential new physics. These measurements rely on accurate reconstruction of decay events through coincident detection of electrons and low-energy protons using two highly segmented silicon detectors located at opposite ends of the Nab spectrometer. This talk will discuss the performance of the experiment's timing synchronization framework, including its validation through controlled tests and detailed analysis of timing residuals. We will also outline ongoing and future efforts to enhance the reliability and coherence of the data acquisition system—ensuring it meets the stringent demands of Nab's precision measurement goals.
