We present the results of the first TOFLAR (Time Of Flight and LARmor precession) experiment with a Larmor modulation device positioned after the sample. Using a setup based on the configuration of the SNS-NSE spectrometer (Spallation Neutron Source, USA), we did TOFLAR measurements on water at 5 and 20 degree Celsius, analyzed the spectra, and obtained diffusion coefficient values that are in a reasonable agreement with literature. Thus, our results demonstrate that TOFLAR may become a standard technique to study quasielastic neutron scattering in future.
