The Materials Life Science Facility (MLF) in the Japan Proton Accelerator Research Complex (J-PARC) adopted the event data recording methods on the data acquisition system (DAQ). In this method, both of the time and position information for neutron detections are recorded. Recently we developed successfully a DAQ electric module TrigNET, which records common electric signals as events synchronized with neutrons. TrigNET will connect with instrument devices and gather output signals from them, i.e. sample direction from goniometers, thermometers for sample and phase information from choppers controller. By analyzing events from TrigNET, neutron events can be filtered for each condition users want to see. This filtering method enables users to measure and analyze the information of the sample under various outer conditions more easily.
