MyNeutronDAQ: A general program for data acquisition of neutron scattering spectrometers at China Mianyang Research Reactor and on‐line data‐analysis

Abstract

MyNeutronDAQ, a graphical user interface (GUI) program for data acquisition of neutron scattering spectrometers at China Mianyang Research Reactor (CMRR) and on‐line data‐analysis has been developed. The program is written in Microsoft Visual C++, which runs under Windows operating systems. Based on the characters of the hardware connection and time‐to‐digital converter (TDC) systems of the spectrometers (taking the time‐of‐flight and polarized neutron reflectometer [TPNR] Diting as the example), a valid event identification and screening protocol is embedded into the program. Moreover, the program design and key features of MyNeutronDAQ such as visualization interface, optional output data format, batch mode, and functions of user‐friendly on‐line analysis, are presented. Taking the program specifically for small‐angle neutron scattering (SANS) Suanni as the example, specific applications of the MyNeutronDAQ are further presented.

Applications of neutron spin echo in soft matter

“…Nonetheless, the availability of inelastic NSE and SESANS spectrometers remains limited, falling significantly short of meeting the scientific community's demands for diverse material explorations. Recently, two NSE spectrometers, both an inelastic LRNSE (longitudinal neutron resonance spin-echo) and a SESANS spectrometer, are commissioning at the China Mianyang Research Reactor (CMRR) [10,131]. We expect a bright future of broad applications of NSE technology in soft matter sciences.…”
