Resumen
High-resolution di ractometer is one of the rst instruments of the set of 15 priority neutron scattering
instruments to be installed at the Brazilian Multipurpose Reactor (RMB). A basic project of this instrument
consists of the existence of three guides through which neutrons pass from source to sample to
guarantee maximum neutron
ux at the sample position. In this study we investigate guide geometry
performance considering xed di ractometer geometry and spatial arrangement. Comparisons between
di erent guide shapes and supermirrors are performed using software based on the Monte Carlo method,
McStas. Our conclusion shows that a better solution is splitting the initial
ux into two di erent guides
to obtain the maximum
ux at the sample position. Conselho Nacional de Desenvolvimento Cient??fico e Tecnol??gico (CNPq) CNPq: 381565/2018-1; 380183/2019-6
