In: INTERNATIONAL NUCLEAR ATLANTIC CONFERENCE, October 21-25, 2019, Santos, SP. <b>Proceedings...</b> Rio de Janeiro: Associação Brasileira de Energia Nuclear, 2019. p. 1184-1189. Disponível em: http://repositorio.ipen.br/handle/123456789/30557.http://repositorio.ipen.br/handle/123456789/30557Monte Carlo simulations are performed for a vertical S-shaped neutron guide for the cold neutron sources of the FRM-II, HZB and PSI reactors through the McStas software. The aim of our study is investigate a relation between the cuto in the cold neutron spectrum and the sources. Results for the neutron ux at the sample position are presented for di erent supermirrors with m = 1, 2 and 3. The vertical S-shaped neutron guides additionally provide a vertical displacement between beam hole and sample position, which can facilitate the implementation and manipulation of sample environments.1184-1189openAccesscold neutronscomputer codesmonte carlo methodneutron fluxneutron guidesneutron sourcesneutron spectraTexto completo de evento0000-0002-6318-6805https://orcid.org/0000-0002-6318-6805
