Abstract

miniBELEN is a modular and transportable neutron moderated counter with a nearly flat neutron detection efficiency up to 10 MeV. Modularity implies that the moderator can be reassembled in 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 (𝛼, 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 252Cf sources and the measurement of the 27Al(𝛼, 𝑛) 30P reaction is also presented.

miniBELEN:用于(𝜶，)反应的模块化中子计数器

miniBELEN是一种模块化和可移动的中子慢化计数器，具有高达10兆电子伏的几乎平坦的中子探测效率。模块化意味着慢化剂可以以不同的方式重新组装，以获得不同类型的响应。该探测器是在测量α中子产率(MANY)合作的背景下开发的，这是一项科学努力，旨在测量(gr，𝑛)产率，反应截面和中子能谱。在这项工作中，我们提出并讨论了miniBELEN探测器的几种配置。实验验证了252Cf源的效率计算和27Al(时延，𝑛)30P反应的测量结果。
