Modularity implies that the moderator can be reassembled m different ways in order to obtain different types of response. The detector has been developed in the context of the Measurement of Alpha Neutron Yields (MANY) collaboration, which is a scientific effort aiming to carry out measurements of (alpha, n) production yields, reaction cross-sections and neutron energy spectra. In this work we present and discuss several configurations of the miniBELEN detector. The experimental validation of the efficiency calculations using Cf-252 sources and the measurement of the (27)A1(alpha, n)P-30 reaction is also presented.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/conference paperhttps://dx.doi.org/10.1051/epjconf/202328406004https://www.epj-conferences.org/articles/epjconf/abs/2023/10/epjconf_nd2023_06004/epjconf_nd2023_06004.htmlopen access539.1Física nuclear2207 Física Atómica y Nuclear
