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 next step in the Wendelstein stellarator line is large superconducting device 7-X, currently under construction Greifswald, Germany. Steady-state operation an intrinsic feature of stellarators, and one key element 7-X mission to demonstrate steady-state plasma conditions relevant for a fusion power plant. device, on hand, requires implementation special technologies, giving rise technical challenges during design, fabrication assembly such device. On other also physics development at...
The thermal diffusivity (TD) and conductivity (TC) of Cu–Cr–diamond composite materials were examined in the temperature range from 50 to 300 °C for diamond volume fractions 22, 40, 50, 55, 60 %. samples fabricated by plasma pulse sintering (PPS) method. TC does not increase proportionally with fraction particular materials. highest TD was determined % fraction, evaluated reached 658 W m−1 K−1 at °C. This article complements earlier articles concerning synthesis characterization...
Abstract Antimony telluride (Sb 2 Te 3 ) is an intermetallic compound crystallizing in a hexagonal lattice with R-3m space group. It creates c lose packed structure of ABCABC type. As intrinsic semiconductor characterized by excellent electrical properties, Sb widely used as low-temperature thermoelectric material. At the same time, due to unusual properties (strictly connected structure), antimony exhibits nonlinear optical including saturable absorption. Nanostructurization, elemental...
Results are presented for the dust survey performed at JET after second experimental campaign with ITER-Like Wall: 2013–2014. Samples were collected on adhesive stickers from several different positions in divertor both tiles and carrier. Brittle dust-forming deposits test mirrors inner wall also studied. Comprehensive characterization accomplished by a wide range of high-resolution microscopy techniques, including focused ion beam, has led to identification classes particles: (i) beryllium...
The influence of the annealing temperature on deuterium retention was studied for self-ion damaged tungsten in range from 600–1200 K. Samples were by 20 MeV W ions at room to peak damage level 0.5 dpa. then annealed desired 1 h and exposed atom beam with flux 144 populate remaining defects. An unannealed sample also used as a reference. Nuclear reaction analysis technique depth profile thermal desorption performed same samples measure amount total retained D. Scanning transmission electron...
Polycrystalline tungsten (W) samples were simultaneously irradiated by 10.8 MeV W ions and exposed to 300 eV deuterium (D) at different temperatures ranging from 450 K 1000 K. After simultaneous ion irradiation D exposure the additionally low-energy in order populate all defects created beforehand. The amount of damage was evaluated measuring depth profiles thermal desorption spectra. Results compared with data obtained a sequential experiment where first only afterwards defects. At we...
This article describes the DEMO cryostat, vacuum vessel, and tokamak building as well system configurations to integrate main in-vessel components auxiliary systems developed during Pre-Conceptual Design Phase. The vessel is primary component for radiation shielding containment of tritium other radioactive material. Various required operate plasma are integrated in its ports. together with external magnetic coils located inside even larger cryostat that has function provide a enable...
Abstract Single crystalline tungsten was irradiated by the medium-mass ion Si with 7.5 MeV and high mass-ion W 20.3 up to a calculated peak damage level of 0.04 dpa 0.5 dpa. The obtained dislocation structure zone investigated transmission electron microscopy systematically compared each other. Bright-field kinematical images were taken under four different two-beam diffraction conditions g = −200, 020, −110, 110 close [100] axis. observed depth position is in good agreement SRIM profiles....
