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...
The ordering of quantum dots in three-dimensional dot lattices is investigated by grazing-incidence small-angle X-ray scattering (GISAXS). Theoretical models describing GISAXS intensity distributions for three general classes are proposed. differ the type disorder positions dots. enable full structure determination, including lattice type, parameters, and degree sizes. Applications developed demonstrated using experimentally measured data from several types formed a self-assembly process.
Gross and net erosion of tungsten (W) other plasma-facing materials in the divertor region have been investigated deuterium (D) helium (He) plasmas during dedicated experiments L- H-mode on ASDEX Upgrade after full-length experimental campaigns WEST tokamak. Net was determined via post-exposure analyses plasma-exposed samples full-size wall components, we conclude that same approach is applicable to gross if marker structures with sub-millimeter dimensions are used eliminate contribution...
Laser-induced periodic surface structures (LIPSSs) and chemical composition changes of Ti-based nanolayered thin films (Al/Ti, Ni/Ti) after femtosecond (fs) laser pulses action were studied. Irradiation is performed using linearly polarized Ti:Sapphire fs 40 pulse duration 800 nm wavelength. The low spatial frequency LIPSS (LSFL), oriented perpendicular to the polarization with periods slightly lower than irradiation wavelength, was typically formed at elevated fluences. On contrary, high...
Abstract Ge/Si core/shell quantum dots (QDs) recently received extensive attention due to their specific properties induced by the confinement effects of core and shell structure. They have a type II resulting in spatially separated charge carriers, electronic structure strongly dependent on size. Herein, experimental realization QDs with tunable optical is demonstrated. embedded an amorphous alumina glass matrix are produced simple magnetron sputtering deposition. In addition, they...
Determination of the deposition order different writing tools is very important for forensic investigation questioned documents. Here we present a novel application two ion beam analysis (IBA) techniques: secondary mass spectrometry using MeV ions (MeV-SIMS) and particle induced X-ray emission (PIXE) to determine intersecting lines made ballpoint pen ink, inkjet printer laser toners. MeV-SIMS an emerging technique where incident heavy are used desorb molecular from uppermost layers organic...
Laser Induced Breakdown Spectroscopy (LIBS) method is considered to be a promising tool for analyzing the retention of hydrogen isotopes (D and T) helium (He) on first walls divertor regions future fusion reactors. Helium will produced in DT reactions but could also used initial non-nuclear phases DEMO concepts. The present study investigates He detection by LIBS Be coatings simulating deposits plasma-facing components JET while results are relevant other wall materials. was carried out...
Nanostructuring of surfaces and two-dimensional materials using swift heavy ions offers some unique possibilities owing to the deposition a large amount energy localized within nanoscale volume surrounding ion trajectory. To fully exploit this feature, morphology nanostructures formed after impact has be known in detail. In present work response rutile TiO 2 (001) surface grazing-incidence irradiation is investigated. Surface tracks with well intermittent inner structure were successfully...
We have investigated retention of plasma fuel in beryllium-containing, laboratory-made films whose properties resemble codeposits observed on JET-ILW or predicted for ITER.The best correspondence the produced layers to results terms composition, surface properties, and (deuterium) release characteristics is obtained by preparing using high-power impulse magnetron sputtering keeping sample temperature at 100-200°C during deposition phase.We notice that carbon impurities play a large role...
