Horizont 2020 Grant No 633053 EUROfusion - Názov/Title: Euratom research and training program 2014-2020. Anotácia/Annotation: EUROfusion projekt riešil experimentálne a teoreticky fyzikálne poznatky súvisiace s experimentom ITER po spustení prevádzky. Naša práca v projekte EUROfusion v pracovnej skupine WP PFC súvisela so štúdiom PFC (komponentov prvej steny dochádyajúcej do priameho kontaktu s plazmou). Z navrhovaných experimentálnych podmienok práce reaktora ITER sa požaduje odolnosť PFC voči neutrónom, tepelným tokom,ktoré môžu sposobovať nevratnú deštrukciu PFC. Naviac počas generácie plazmy v reaktore dochádza k rozprašovania materiálu PFC, jeho migrácii a následnej redepozícii. Vytvárajú sa BeWO vrstvy , ktoré veľmi efektívne zachytávajú palivo D/T. Monitorovanie záchytu paliva bol jeden z hlavných problémov, ktorý sa riešil vrámci WP-PFC pracovnej skupiny. / The EUROfusion project addressed the experimental and theoretical physical knowledge related to the ITER post-commissioning. Our work in the EUROfusion project in the WP PFC working group was related to the study of PFC (components of the first wall coming into direct contact with plasma). The proposed experimental operating conditions of the ITER reactor require the resistance of PFCs to neutrons, heat fluxes that can cause irreversible destruction of PFCs. In addition, during the generation of plasma in the reactor, the PFC material is sputtewred, migrated and redepositied . Created BeWO layers can retein capture D/T fuel very efficiently. Fuel retention monitoring was one of the main issues addressed by the WP-PFC Working Group.

Anotácia/Annotation: Projekt patrí do tematiky materiálového výskumu a nanotechnológií. Zaoberal sa štúdiom relevantných materiálov pre steny fúznych reaktorov so zameraním sa na záchyt paliva, migráciu materiálu stien, tvorbu nanodefektov a rast vrstiev. Základnou metódou projektu bola laserom indukovana breakdown spektroskopia (LIBS) na priestorovú analýzu skúmaných povrchov (v závislosti od polohy a hĺbky). Cieľom projektu bola stratégiu na zosilnenie a analýzu signálu LIBS, pri redukcii hmotnosti ablovaného materiálu. Dosiahlo sa hĺbkové rozlíšenie na úrovni niekoľko desiatok nm pri použití ps laserovej ablácie a simultánnej Vákuovej UV LIBS spektroskopii. / The project belongs to the material and nanotechnology research. It deals with the study of relevant materials for fusion reactor walls with a focus on the fuel retention, wall material migration, nano-defects formation, and growth of deposited layers. The basic method of the project was laser-induced breakdown spectroscopy (LIBS) for spatial analysis of the studied surfaces (depending on the position and depth). The aim of the project was a strategy to amplify and analyze the LIBS signal, while reducing the weight of the ablated material. Depth resolution of several tens of nm was achieved using ps laser ablation and simultaneous Vacuum UV LIBS spectroscopy. Druh činnosti / Role: zodpovedný riešiteľ / principal investigator.

VEGA 1/0803/21 - Názov/Title: Laserom indukovaná plazmová analýza tenkých vrstiev a tekutín s cieľom zlepšenia jej citlivosti a priestorového rozlíšenia / Laser Induced Plasma Analysis of Thin Films and Liquids for the Improvement of its Sensitivity and Spatial Resolution. Anotácia/Annotation: Tento projekt má dva hlavnmé ciele, zlepšenie citlivosti a priestorového rozlíšenia v laserovej plazmovej analýze na štúdium tenkých vrstiev a vzoriek tekutín. Na zlepšenie citlivosti metódy LIBS sa budú študovať rôzne prístupy, ako sú súčasné VUV­NIR LIBS, DP­LIBS, LIBS v kombinácii s el. výbojmi, plazmové rezonančné LIBS a povrchovo podporované LIBS. Na tento účel sa použijú roztoky ťažkých kovov vysušené na vysoko reflexnom povrchu. Zlepšenie citlivosti povedie k lepším LOD a pomerom signal/šum profilometrii, rozšíreniu a separácie izotopov, ak sa pridá spektrometer s vysokým rozlíšením. Na dosiahnutie druhého cieľa budú ablátované krátery študované pomocou 3D profilometriou, AFM a SIMS v spolupráci s Medzinárodným laserovým centrom (MLC). To nám umožní nielen overiť, ale aj doplniť naše výsledky LIBS. / This project has two main goals, the improvement of the sensitivity and the spatial resolution in laser plasma analysis for the study of thin films and liquid samples. To improve the sensitivity of the method, different approaches will be studied, such as simultaneous VUV-NIR LIBS, DP-LIBS, LIBS with el. discharges, plasma-resonant LIBS, and surface-assisted LIBS. For this, heavy metal solutions dried onto a highly-reflective surface will be used. The improvement in the sensitivity will lead into a better LOD and signal/noise ratio in profilometry, extensions and isotopes separation if a high-resolution spectrometer is added. For achieving the second goal, the ablated craters will be studied by a 3D profilometry, AFM and SIMS in collaboration with the International Laser Centre (ILC). This will allow us not only to verify but also to supplement our LIBS results. Druh činnosti / Role: zodpovedný riešiteľ / principal investigator.
