We report the current status of software development about "Utsusemi" and its applications for the effective utilization of event-recording data on the Materials and Life Science Experimental Facility (MLF), the Japan Proton Accelerator Research Complex (J-PARC). "Utsusemi" is the one of analysis software frameworks utilized for the data reduction and visualization in MLF, including treatment of event-recorded data. MLF adopted the event-recording method on the data acquisition system (DAQ), which records the time and position information of neutron detections. In addition, the time and common electric signals can be recorded as events at same time by using of the TrigNET module in DAQ. This module connects with instrument devices and gathers their output signals to recode with same time stamp as neutron detection events completely. Treating these event data, Utsusemi can pull out individual data for each sample condition to analyze from one measurement data. This method has been already used for many MLF users. For example, we successfully carried out some users’ measurements and analyzed the data under the pulse-shaped magnetic field and alternating electric field. In addition, we also realized a "pseud-online" analysis using event-recorded data. In this presentation, we will show the current status of our works.
