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 (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 252Cf sources and the measurement of the 27Al(alpha,n)30P reaction is also presented., Comment: 15th International Conference on Nuclear Data for Science and Technology (ND2022)

miniBELEN-10A is a modular and transportable moderated neutron counter with a nearly flat detection efficiency up to 8 MeV. The detector was designed to carry out measurements of (alpha, n) reactions in the context of the Measurement of Alpha Neutron Yields (MANY) project. In this work we present the results of the commissioning of miniBELEN-10A using the relatively well-known thick-target neutron yields from 27Al(alpha, n)30P.

The DEcay SPECtroscopy (DESPEC) setup for nuclear structure investigations was developed and commissioned at GSI, Germany in preparation for a full campaign of experiments at the FRS and Super-FRS. In this paper, we report on the first employment of the setup in the hybrid configuration with the AIDA implanter coupled to the FATIMA LaBr3(Ce) fast-timing array, and high-purity germanium detectors. Initial results are shown from the first experiments carried out with the setup. An overview of the setup and function is discussed, including technical advancements along the path.

In this work, we present the design of a new modular and transportable neutron detector for ({\alpha},n) reactions. The detector is based on the use of several 3He-filled proportional counters embedded in high density polyethylene. In order to provide the detector with a response independent of the neutron energy, a flat response, an innovative design methodology has been applied. The method is based on the optimization of the counters contribution to the total efficiency by using thermal neutron absorbers. This allows to obtain flat responses up to 10 MeV. The characterization of a proof-of-concept prototype detector is presented. The perspectives for using this new detector for ({\alpha},n) reactions measurements are discussed., Comment: Proceedings del XXII Simposio Chileno de Fisica, 2020, submitted ato Journal of Physics: Conference Series

Beta-delayed neutron emission plays a fundamental role in the explosive nucleosynthesis of elements heavier than iron by the rapid neutron capture (r-process). The most ambitious project related to beta-delayed neutron detection of very exotic nuclei is carried out by the BRIKEN collaboration at RIKEN Nishima Center. In this work, a brief description of the BRIKEN project is presented. A methodology for the precise characterization of the BRIKEN neutron counter efficiency, for fast neutrons, using an uncalibrated 252Cf neutron source is described. The method relies on the well-known neutron multiplicity distribution of such source and correlation counting method. A detailed experimental study with the BRIKEN neutron counter and a 252 Cf neutron source at the RIKEN Nishina center is presented. The result of this work is the determination of the neutron detection efficiency of the BRIKEN neutron counter with high accuracy., Comment: Proceedings del XXII Simposio Chileno de Fisica, 2020, submitted ato Journal of Physics: Conference Series
