Analysis and understanding of wall erosion, material transport fuel retention are among the most important tasks for ITER future devices, since these questions determine largely lifetime availability fusion reactor. These data also extreme value to improve validate models in vessel build-up T inventory D–T devices. So far, research areas is supported by post-mortem analysis tiles. However, access samples will be very much restricted next-generation devices (such as ITER, JT-60SA, W7-X, etc)...
The provision of a particle and power exhaust solution which is compatible with first-wall components edge-plasma conditions key area present-day fusion research mandatory for successful operation ITER DEMO. work package plasma-facing (WP PFC) within the European programme complements laboratory experiments, i.e. in linear plasma devices, electron ion beam loading facilities, studies performed toroidally confined magnetic such as JET, ASDEX Upgrade, WEST etc. connection both groups done via...
Production of ZnO nanorods with high crystallographic purity and PL emission properties.
The aim of the present research is to validate combined use, through data fusion, a Laser Induced Fluorescence (LIF) scanning system and radar scanner (RGB-ITR, Red Green Blue Imaging Topological Radar system), as unique tool address need for non-invasive, rapid, low-cost techniques both diagnostic operational needs. integrated has been applied House Diana complex in Ostia Antica. main objective this was trace materials used different phases restoration, from antiquity modernity, on masonry...
Since the 2012 IAEA-FEC Conference, FTU operations have been largely devoted to runaway electrons generation and control, exploitation of 140 GHz electron cyclotron (EC) system liquid metal limiter elements. Experiments on shown that measured threshold electric field for their is larger than predicted by collisional theory can be justified considering synchrotron radiation losses. A new control algorithm was developed tested in presence a current plateau, allowing minimize interactions with...
Abstract In nature, calcium carbonate (CaCO 3 ) in the form of calcite and aragonite nucleates through different pathways including geogenic biogenic processes. It may also occur as pyrogenic lime plaster laboratory-precipitated crystals. All these formation processes are conducive to degrees local structural order CaCO crystals, with precipitated forms being least ordered. These variations affect manner which crystals interact electromagnetic radiation, thus be tracked using methods such...
In spite of difficulties in quantitative LIBS analysis on copper based alloys, the very low invasiveness technique strongly sustains attempts to use it with cultural heritage materials, including ancient bronzes. Analytical results obtained calibration curves and a free model are compared here set roman coins. An attempt is presented monitor laser ablation process bronze coins artificially aged standards during cleaning. The double pulse showed that analytical could benefit from...
In this paper the Laser Induced Breakdown Spectroscopy (LIBS) measurement of deuterium (used as a proxy for tritium) retained in and surface elemental composition FTU Mo (TZM) toroidal limiter tiles, carried out from remote (∼2.5 m) during short breaks operations or machine maintenance, are reported. Single pulse technique has been used with vessel under high vacuum Nitrogen Argon atmosphere. experiments Dα Hα lines have detected good resolution, while Ar atmosphere (5 × 104 Pa) two were...
The most meaningful spectral components in laser-induced fluorescence (LIF) spectra for several different commercial plastics have been individuated and used to automatically discriminate among plastic materials between complex organic materials, such as woods. Starting from LIF measurements on known samples, a number of significant wavelengths identified by principal component analysis (PCA). These produce intensity ratios functional the discrimination. Threshold values order obtain an...
This study presents a comparison of the piezoelectric properties nanostructured thin films made arrays vertically oriented ZnO-nanorods (ZnO-NRs) over ITO-glass substrate and ZnO-nanowalls (ZnO-NWs) aluminium substrate. Both nanostructures were synthesized on large area through chemical bath deposition. The morphological, structural, characteristics produced investigated in order to assess crystal quality purity. To this purpose, we used different techniques, such as field-emission scanning...
