[en] The response functions of a REM counter and a neutron dosimeter were measured in the epi-thermal and the intermediate velocity regions by using a LINAC-TOF system. The efficiency curves for two types of the neutron dosimeters with moderators were measured and analyzed. The dead time correction of the time analyzer and the correction of time resolution were made for the data. The adjoint calculation by the ANISN code was made. The experimental and the calculated results were mutually compared. The preliminary works on the angle dependence of the efficiency of the detectors are in progress. As the results of this study, it was found that a method to obtain the energy dependent efficiency curves has been established. The correction of time resolution is important. The upper limit of the range of application of correction for energy is about 1 keV. (Kato, T.)
