| 英文摘要 | The multipurpose physics neutron diffractometer (mp) will be built at the china spallation neutron source (csns) in the coming years. it is a time of flight diffractometer dedicated to the study of complex crystalline materials through the total scattering or pair distribution function (pdf) technique. the mp diffractometer will be able to determine the pdf from the atomic to the nanometer scale. we present a validation of the main physical parameters of the mp diffractometer through monte carlo simulation. in particular the moderator choice, guide system and placement of the chopper system is investigated. the best momentum transfer resolution delta q/q is reached in backscattering and is expected to be in the order of 0.2 %, the neutron flux at the sample is of the order of 10(7) n/s/cm(2) and the momentum transfer range in the order of 0.08-100 angstrom(-1). |
