Abstract. Cosmic-ray neutron sensing (CRNS) has emerged as a reliable method for soil moisture and snow estimation. However, the applicability of this beyond research been limited due to, among others, use relatively large expensive sensors. This paper presents tests conducted on new scintillator-based sensor especially designed to jointly measure counts, muons total gamma rays. The signal is first compared against two conventional gas-tube-based CRNS sensors at locations. estimated further...
Abstract Within the INFN HYDE project, we have developed pixelated hybrid detectors for thermal neutron imaging. Devices are based on microstructured silicon sensors coupled with converter materials. Compared to standard 3D sensors, proposed device offers a more convenient trade-off between technological complexity and detection performance. Nevertheless, experimental results shown lower efficiency respect theoretically expected value, which was attributed an insufficient density of negative...
Hydrogenated amorphous silicon (a-Si:H) devices on flexible substrates are currently being studied for application in dosimetry and beam flux measurements. The necessity of vivo requires thin with maximal transparency flexibility. For this reason, a (<10 µm) a-Si:H device deposited polyimide sheet is very valid option application. Furthermore, material that has an intrinsically high radiation hardness. In order to develop these devices, the HASPIDE (Hydrogenated Amorphous Silicon Pixel...
Abstract Measuring the variability of incoming neutrons locally would be usefull for cosmic‐ray neutron sensing (CRNS) method. As measurement high energy is not so easy, alternative particles can considered such purpose. Among them, muons are created from same cascade primary fluxes that generate at ground. In addition, they easily detected by small and relatively inexpensive detectors. For these reasons could provide a suitable local to corrections based on remote monitor data. The reported...
