Neutrons are studied in various domains as, for example, particles of interest in fundamental physics, tool in biology and elemental analysis, or danger for human in radioprotection. The measurement of the neutron energy is necessary in all these domains, but the characteristics of the spectrometers can vary greatly from an application to another. In the field of this thesis, we conceived a recoil proton telescope using ultra-fast CMOS pixels sensors. This compact detector allows a real-time reconstruction of the neutron spectrum up to very high flux. The applications developed during this thesis are precision measurement at the AMANDE accelerator between 4 and 20 MeV, as part of a collaboration with IRSN-Cadarache, and the characterization of secondary neutrons produced in protontherapy treatment rooms

Due to their inherent relationship with the binding energy, nuclear masses are the fingerprint of all the interactions taking place within the nucleus. As such, precise and accurate mass values are an essential ingredient to the comprehensive understanding of nuclear phenomena in exotic regions of the chart of nuclides. In this thesis, two key regions exhibiting dramatic structural evolution are investigated by means of high precision mass measurements performed with the online mass spectrometer ISOLTRAP at ISOLDE/CERN. Numerous spectroscopy results indicate that the chromium isotopic chain exhibits the most dramatic structural changes within the region situated south of 68Ni. This thesis reports on the first high-precision mass measurements of the neutron-rich 58-63Cr isotopes using the well established Penning trap mass spectrometry technique as well as the MRToF-MS technique pioneered at ISOLTRAP in recent years. The obtained mass values are up to 300 times more precise than the ones currently available in the literature. At odds with previous results, the new mass values exclude a sudden onset of ground-state collectivity rather favouring a smooth transition towards deformation approaching N=40. The question of the persistence of the N=28 shell closure in the Argon chain is also studied in this PhD work through the measurement of the neutron-rich 46-48Ar isotopes. The results of improved precision confirm the presence of a strong N=28 shell closure in the Argon chain. For both datasets, the detailed data analysis procedure will be presented. The implication of the obtained mass values for nuclear structure will be discussed through a phenomenological discussion of the binding energy trend. The results will also be discussed in the light of state of the art nuclear models including results from the promising valence-space formulation of the ab-initio IM-SRG formalism

Measuring the neutron and gamma ray fluxes produced by the interaction of galactic cosmic rays with planetary surfaces allow constraining the chemical composition of the upper tens of centimeters of material. Two different angles are proposed to study neutron and gamma spectroscopy: data processing and data interpretation. The present work is in line with two experiments, the Mars Odyssey Neutron Spectrometer and the Selene Gamma Ray Spectrometer. A review of the processing operations applied to the MONS dataset is proposed. The resulting dataset is used to determine the depth of the hydrogen deposits below the Martian surface. In water depleted regions, neutron data allow constraining the concentration in elements likely to interact with neutrons. The confrontation of these results to those issued from the Gamma Ray Spectrometer onboard Mars Odyssey provides interesting insight on the geologic context of the Central Elysium Planitia region. These martian questions are followed by the study of the Selene gamma ray data. Although only preliminary processing has been done to date, qualitative lunar maps of major elements (Fe, Ca, Si, Ti, Mg, K, Th, U) have already been realized

Ln the framework of radioactive waste drums control, difficulties arise in the non-destructive measurement of fissile mass 235U, 239PU. . . ) by Active Neutron Interrogation (ANI), when dealing with matrices containing materials (CI, H. . . ) influencing the neutron flux. The idea is to use the neutron capture reaction (n,y) to determine the matrix composition to adjust the ANI calibration coefficient value. This study, dealing with 118 litres, homogeneous drums of density less than 0,4 and composed of chlorinated and/or hydrogenated materials, leads to build abacus linking the y-ray peak areas to the ANI calibration coefficient. Validation assays ofthese abacus show a very good agreement between the corrected and true fissile masses for hydrogenated matrices (max. Relative standard deviation: 23 %) and quite good for chlorinated and hydrogenated matrices (58 %). The developed correction method improves the measured values. It may be extended to 0,45 density, heterogeneous drums

The DONEUT (DOsimètre NEUtrons) project in which this thesis is included, has to answer to the following issue for the civilian an military nuclear industries : a more precise determination of the neutron impact on the human body, fundamental in radiation protection.To fulfill theses requirements, which consist of measuring an ambient or personal dose equivalent rateS (H*(10) or Hp(10)) from 1 µSv/h to ~10 mSv/h in less than 10 minutes, a transportable (mass ≤ 15 kg) multi detectors cylindric prototype has been developed, with 32 thermal neutron detectors placed at different depths.This device is able to rebuild a full neutron spectrum from 0 to 20 MeV through unfolding computer codes like MAXED and GRAVEL, and the results are in good agreement with those obtained with the NNS spectrometer (Nested Neutron Spectrometer), which was our reference, with a good gamma/neutron discrimination
