摘要: A growing community of scientists has been using neutrons in the most diverse areas science. In order to meet researchers demand physics, chemistry, materials sciences, engineering, cultural heritage, biology and earth Brazilian Multipurpose Reactor (RMB) will provide 3 thermal guides cold guides, with installation several instruments for characterization. this study, we present a standard design requirement two primordial instruments, namely Sabia Araponga. They are, respectively, neutron correspond Small-Angle Neutron Scattering (SANS) High-Resolution Powder Diffractometer (HRPND) be installed Guide Building (N02) RMB. To adequate flux both propose here an initial investigation use simple split transport beams different on same guide. For purpose, Monte Carlo simulations utilizing McStas software check efficiency basic configuration sources. By considering these results, it is possible conclude that guide is, cases, more efficient than cases transmitted independently source. We also verify employment coating indexes concave convex surfaces curved crucial, at least simulated optimise (intensity divergence) diminish facility cost.
