In order to achieve processing of data calibrated by neutron spectrometer

and complete neutron spectrometer sample stage motion simulation

interactive data language（ IDL） language is used to carry out software development of human-computer interaction interface and sample motion simulation of diffraction measurement is achieved by relying on the software. Interface flow is determined according to interface process determined by the needs of the actual calibration process

the three-dimensional visual scene of sample stage is established by threedimensional visualization principle

human-computer interaction is achieved by building the event management mechanism. Motion simulation model of sample stage is established. Example demonstration is presented according to experimental data. The simulation results show that the sample stage can move the sample measurement points to the neutron diffraction points in turn

and the measurement vectors are aligned with the scattering vectors to achieve neutron diffraction measurement.
