Annotation:

In this project, thin films are being manufactured by different methods in a thin film deposition set-up and subsequently characterized. This is done in order to determine if the set-up is capable of producing films of sufficient quality to be used for research purposes in the ion physics group of the division of applied nuclear physics at Uppsala University. Both copper and silver films are manufactured by magnetron sputtering deposition. Copper films are also manufactured by evaporation deposition. Deposition is made on Si(001) substrates. The films are analyzed with Rutherford Backscatterin

During several decades of research and development in the field of Magnetically Confined Fusion (MCF) the preferred selection of materials for Plasma Facing Components (PFC) has changed repeatedly. Without doubt, endurance of the first wall will decide research availability and lifespan of the first International Thermonuclear Research Reactor (ITER). Materials erosion, redeposition and mixing in the reactor are the critical processes responsible for modification of materials properties under plasma impact.

Este trabalho tem por objetivo a caracterização de filmes finos de óxido de alumínio produzidos por deposição assistida por feixe de íons Ar+. Tal caracterização consiste em estabelecer a relação entre os parâmetros de produção (energia do feixe e uxo relativo de Ar), a composição e a estrutura dos lmes. Para tanto, utiliza-se técnicas de microscopia de força atômica, difração de raios-x, reetividade de raios-x e análise por feixe iônico. Resultados mostram que amostras produzidas à temperatura ambiente e à 450 oC são amorfas independentemente da energia do feixe iônico. Filmes formados com as

Ion beam analysis (IBA) has been used as a powerful tool for studying materials for many years. Depending on the specific experimental design, IBA techniques can provide a non-destructive means of analysing samples to obtain such information as the elements or isotopes present and diffusion or depth profiles. Ion beam analysis has the ability to keep up with the rapid progress in new materials both as technology improves and as scientists have the creativity to develop existing and new techniques. Many different types of IBA exist. The experiments reported in this thesis were carried out using

With the rapid spread in use of polymers the study of diffusion in them is becoming increasingly important. For a number of industrial processes diffusion coefficients and elemental distributions need to be quantified precisely.

Using ion beam analysis techniques (Rutherford Backscattering and Nuclear Reaction Analysis) three systems were studied. The first was an industrially relevant s

Předložená diplomová práce se zabývá implementací metody rentgenové emisne indukované částicemi do experimentálního uspořádání za účelem doplnění rodiny metod založených na iontových technikách, tj. Rutherfordovy zpětné rozptylové spektrometrie, spektrometrie elastického zpětného rozptylu a analýzy detekce doby letu/energie elastického odrazu. Výhoda více-metodického přístupu je demonstrována na vrstvách ze slitin přechodných kovů obsahujících lehké prvky, kde samo-konzistentní analýza poskytuje výrazně zlepšené a přesné informace o stechiometrii, hloubkovém rozložení a tloušťce slitiny.

The DART ion source was introduced in 2005 at the ASMS Sanibel Conference and immediately afterward Professor Sparkman was contemplating of a way to get our lab this revolutionary mass spectrometry ionization technique. It did not take long because it was delivered to the Pacific Mass Spectrometry Facility in August 2006 and I was able to being using and learning the technique. The ion source creates excited state helium metastables (2 3 S) with an ionization potential of 19.8 eV are created by a glow discharge at atmospheric pressure. The metastables are sent through an optional heater, to ai

Les nano-applications utilisant des faisceaux d'ions focalisés nécessitent des sources d'ions à haute brillance avec une faible dispersion en énergie (ΔE) ce qui permet une excellente résolution latérale et un courant d'ions suffisamment élevé pour induire des vitesses d'érosion raisonnables et des rendements élevés d'émission électronique et ionique. Les objectifs de cette thèse sont le développement d'une source d'ions basée sur l'impact électronique ayant une brillance réduite Br de 10³ – 10⁴ A m⁻² sr ⁻ ¹ V⁻ ¹, une dispersion en énergie ΔE ≲ 1 eV et un choix polyvalent d'ions.

Cette thèse présente de nouveaux développements en détection de particules chargées et traitement tout-numérique d'impulsions pour application à l'analyse avec des faisceaux d'ions rapides (IBA). Un ensemble de 16 détecteurs gravés sur une puce de Si est mis en œuvre, ce qui fournit un angle solide de détection environ 100 fois plus grande que celle des détecteurs utilisés auparavant pour l'IBA. Seize chaines d'acquisition sont également mises en œuvre avec une approche 'tout-numérique' pour le traitement des signaux issus des détecteurs. Dans son ensemble, le système ainsi développé a une rés
