SANS Spectrometer for 1MW NUR reactor at URGN, Algeria

Abstract The small-angle neutron scattering spectrometers (SANS) have received nowadays wide acceptance due to very rich possibilities, which they open for investigations of the structural peculiarities of density and concentration fluctuations on a length scale of 10–1000 E. Due to the large scattering cross-sections at low angles SANS can be used on low-flux neutron sources. We present a new SANS spectrometer which has been designed and manufactured in IPPE and JINR for the 1 MW NUR research reactor at Unite de Recherche en Genie Nucleaire (URGN), Draria, Algeria.
