We have constructed the high-efficiency and medium-resolution powder diffractometer with multi-detector system, HERMES, at JRR-3M reactor at JAERI. A typical counting duration and the best resolution are 2-5 h and 0.3% Δd/d, respectively. We have obtained satisfactory results in crystal and magnetic structure refinement, and diffuse scattering measurements on a single crystal. The instrumental details and experimental performance are presented.
