Real-time data display and storage device for pulsed neutron scattering experiment

摘要

A real-time data display and storage device was developed for neutron scattering experiments. The device contains two sets of field programmable gate arrays and onboard microcomputers for data display and storage. The developed device can determine the time-of-flight and time- resolved neutron position data with a time range from 0 to 40 ms using a beam of pulsed neutrons at 25 Hz. It was confirmed by an operation test using burst and continuous test pulses that the device exhibited a pulse pair resolution of less than 1 μs and a counting rate capability of more than 1 Mcps.
