The concept of the new experimental setup − neutron reflectometer ARMAN (Almaty Reflectometer of MonochromАtic Neutrons) is presented. The instrument is to be placed at beamline 4 with thermal neutrons at the WWR-K reactor of the Institute of Nuclear Physics, Almaty, Kazakhstan. The instrument features a horizontal scattering geometry with a vertically oriented sample with the size of beam 2×50 mm2. The reflectometer will operate with a monochromatic neutron beam in two modes: with and without polarization of the incident beam. The monochromatization will be provided by a double-crystal monochromator of pyrolytic graphite plates with the working wavelength range of 1.8−2.8 Å and expected resolution ∆λ/λ in the range of 1-3%. The schematics and main elements together with the numerical estimates of the expected neutron flux in different places of the beamline are discussed.
