“…We will also look into gathering user experiences once the gateway is operational to improve functionalities and facilitate planning future developments The future development of the CTA Science Gateway will be driven by the present and forthcoming user requirements of CTA community. We are integrating the OpenNebula cluster 34 hosted by the Astrophysical Observatory of Catania (96 CPU cores and 1024GB RAM). This cloud environment will allow to provide an intelligent workload management platform for the ACID services towards overcoming potential bottlenecks in accessing these services.…”

The Cherenkov Telescope Array (CTA) is currently building the next generation, ground-based, very high-energy gamma-ray instrumentation. CTA is expected to collect very large datasets (in the order of petabytes) which will have to be stored, managed and processed. This paper presents a graphical user interface built inside a science gateway aiming at providing CTA-users with a common working framework.

“…Within the MuPortal project [35], a muon tomography system is under construction, with the aim to inspect the presence of high-Z material hidden in cargo containers. The project foresees the use of muon detector modules formed of plastic scintillator bars 128 cm long and of 1.0 cm × 1.0 cm cross section, read out by wavelength shifting fibers, to cover a surface of 2.54 m × 12.80 m.…”

“…While the absorption technique requires the measurement of the muon position and direction only downstream of the object to be inspected, the technique based on muon scattering requires the measurement of muon position and direction both upstream and downstream, to measure the single muon angular deviation. This technique has been proposed for the detection of radioactive "orphan" sources hidden in scrap metal containers [30,31,32,33], to inspect commercial cargoes in ports seeking for hidden "special nuclear materials" [34,35,36,37], to inspect legacy nuclear waste containers [38,39] and to obtain tomographic images of the interior of blast furnaces [40]. In a recent study, the method has been proposed to perform a diagnosis of the damaged cores of the Fukushima reactors [41].…”

Abstract. Cosmic ray radiation is mostly composed, at sea level, by high energy muons, which are highly penetrating particles capable of crossing kilometers of rock. Cosmic ray radiation constituted the first source of projectiles used to investigate the intimate structure of matter and is currently and largely used for particle detector test and calibration. The ubiquitous and steady presence at the Earth's surface and the high penetration capability has motivated the use of cosmic ray radiation also in fields beyond particle physics, from geological and archaeological studies to industrial applications and civil security. In the present paper, cosmic ray muon detection techniques are assessed for stability monitoring applications in the field of civil engineering, in particular for static monitoring of historical buildings, where conservation constraints are more severe and the time evolution of the deformation phenomena under study may be of the order of months or years. As a significant case study, the monitoring of the wooden vaulted roof of the "Palazzo della Loggia" in the town of Brescia, in Italy, has been considered. The feasibility as well as the performances and limitations of a monitoring system based on cosmic ray tracking, in the considered case, have been studied by Monte Carlo simulation and discussed in comparison with more traditional monitoring systems. Requirements for muon detectors suitable for this particular application, as well as the results of some preliminary tests on a muon detector prototype based on scintillating fibers and silicon photomultipliers SiPM are presented.

“…Detailed GEANT4 simulations have been carried out in order to understand and reproduce the performance of our detector and to optimize the algorithms for the reconstruction of the tomographic image [9]- [10]. The main ingredients of the simulations include the implementation of a full replica of the detector, of the support and container; the generation of a realistic distribution of cosmic rays (using the CORSIKA code); the transport of optical photons fully simulated and then parameterized to save CPU time; the reconstruction of hits and clusters, including those due to electromagnetic showers.…”

The Muon Portal Project goal is the design and construction of a working detector prototype in scale 1:1, to inspect the content of travelling containers by means of the secondary cosmic-ray muon radiation and recognize high-Z hidden materials (U, Pu or other fissile samples). The radiographic image is obtained by reconstructing the input and output trajectories of each muon and consequently the scattering angle, exploiting two trackers placed above and below the container. The scan is performed without adding any external radiation, in a reasonable time (a few minutes) and with a good spatial and angular resolution. The detector consists of 8 planes segmented in 6 identical modules. Each module is made of scintillating strips with two WaveLength Shifting fibers (WLS) inside, coupled to Silicon photomultipliers. The customized readout electronics employs trading programmable boards. Thanks to a smart read-out system, the number of output channels is reduced by a factor 10. The signals from the front-end modules are sent to the read-out boards, in order to convert the analog signal to a digital signal, by a comparison to a threshold. The data are pre-analyzed and stored into a data acquisition PC. Actually, an intense measurement and simulation campaign is in progress to characterize carefully the detector components. The first detection modules (1 x 3 m 2 ) is now under construction. The detector architecture with a particular attention to the used electronics and the main preliminary results will be presented.
