Teilchenbeschleuniger - Grundlagen
Guratzsch, H.
Abstract
Ausgehend von der Wirkung elektischer und magnetischer Felder auf elektrisch geladene Teilchen, wie Elektronen und Ionen, wird die Funktion der Teilchenbeschleuniger erläutert. Auf die Analogie zwischen Lichtoptik und Elektronen- bzw. Ionenoptik wird bei der Betrachtung der Strahlführung hingewiesen. Wichtig für das Funktionieren eines Beschleunigers ist die korrekte Berücksichtigung der kinematischen Beziehungen zwischen Energie, Masse und Geschwindigkeit. Mit Hilfe von schematischen Darstellungen werden verschiedene Beschleunigertypen vorgestellt. Die Emission von Synchrotronstrahlung begrenzt bei Elektronen-Kreisbeschleunigern die praktisch erreichbare Energie. Der LEP-Ring im CERN erreicht mit 27 km Umfang eine Energie von 50 GeV. Für noch höhere Energien müssen Linearbeschleuniger gebaut werden. Am TESLA-Projekt für einen 33 km langen Elektronen-Positronen-Collider mit einer Energie im Wechselwirkungspunkt von 500 GeV wird im DESY Hamburg gearbeitet. Auf der Basis der supraleitenden TESLA-Beschleunigungsstrukturen wird derzeit im Forschungszentrum Rossendorf ein 40-MeV-Linearbeschleuniger für Elektronen aufgebaut. In Zukunft werden mit diesem Beschleuniger kern- und strahlungsphysikalische Forschungsarbeiten durchgeführt sowie kohärente Infrarotstrahlung (Freier-Elektronen-Laser) für materialwissenschaftliche Untersuchungen erzeugt.

Applying ANSYS/Multiphysics to In-Vessel and Ex-Vessel Core Melt Phenomena
Willschütz, H.-G.
Abstract
For future nuclear power plants it is demanded that there are no consequences for the environment and the population even in the closest vicinity of the plant during and after every possible accident scenario. This includes the hypothetical scenario of a severe accident with subsequent core meltdown, corium relocation and formation of a melt pool with internal heat sources in the reactor pressure vessel (RPV) lower head (LH). Some reactor concepts have the aim to arrest the melt in the lower head removing the decay heat by external water flooding. In other concepts a dry reactor pit is designed and after the vessel failure a core catcher shall assure the long term stabilization of the corium within the containment.
For both strategies investigations on the transient behaviour of the RPV or of the core catcher are necessary. Two kinds of vessel failure can be distinguished: thermal and structural failure. Thermal failure means that the heat flux through the vessel wall becomes so high that the steel solidus temperature at any position of the vessel outside is exceeded. Structural failure means that a combination of thermal and mechanical loads causes the failure, e. g. the wall thickness of the vessel is reduced by thermal ablation and at the same time the internal pressure and the gravitational forces induce creeping with subsequent creep failure.
Different melt configurations can be assumed. They can be distinguished by the melt masses released into the LH, the melt composition, the segregation behaviour of the oxidic and the metallic component, and the density and the distribution of the internal heat sources. One of the most dangerous accident scenarios for a pressurized water reactor (PWR) assumes the relocation of a melt mass in the range of 200 Mg or more which is segregated into some 150 Mg of the heavier oxidic component at the bottom and some 50 Mg of a metallic melt above. The oxidic melt is surrounded by an oxidic crust due to the high solidification temperature of the oxide. The internal heat sources are mainly in the oxidic component, but due to the geometric configuration and the different fluid properties the highest heat fluxes and the major thermal ablation is expected between the metallic layer and the vessel wall. This phenomenon is called focussing effect.
An in-vessel-scenario of a PWR has been assumed and modelled with ANSYS/ Multiphysics. Using this Finite Element (FE) code package it is possible to simulate the velocity and temperature field for a fluid region and the corresponding temperature field within the surrounding solid structures. This thermo-fluiddynamic calculation can be coupled with a mechanical FE-model of the solid structures to analyse the stress and possible creeping forced by the mechanical and thermal loads. In this presentation, the recent modelling approach and the results obtained with the code ANSYS/Multiphysics are discussed. An outlook on the further development is given.

Ion beam sensitizing of titanium surfaces to hydroxyapatite formation
Pham, M. T.; Matz, W.; Reuther, H.; Richter, E.; Steiner, G.; Oswald, S.
Abstract
CaO and P2O5 containing Ti surfaces were prepared and examined for their bioactivity. The preparation involved the incorporation of Ca and P into Ti by ion implantation to a total dose of up to 8 x 1017 ions/cm² with a 1.7 Ca/P ratio and a subsequent oxidation at 500 °C in O2 for 40 min. The model surfaces were examined for their reactivity toward hydroxyapatite formation by microscopically recording the mineralization in a simulated body fluid. The ion implantation modified surfaces were shown to exhibit enhanced mineralization by inducing heterogeneous nucleation, growth, and proliferation of hydroxyapatite, relative to a control sample of pure Ti. The surface induced reactivity was shown to relate to the enhanced provision of the ionic mineral components Ca2+ and HPO42- directly supplied from the surface and the substrate-mediated nucleation by hydroxylated surface TiO2.

Roles of implantation parameters on the formation of expanded austenite
Parascandola, S.; Betzl, M.; Richter, E.; Möller, W.
Abstract
High-current ion implantation of nitrogen into austenitic stainless steel (AISI 316Ti) at temperatures about 400°C results in the formation of a surface layer, called expanded austenite. A tensor of nitrogen ion energies (1.2, 2.0 and 2.8 keV), ion fluxes (0.2 and 1.0 mA/cm2) and times (2, 10 and 40 min.) has been selected to investigate the roles of the implantation parameters: ion energy, current density and treatment time. In addition, a temperature series has been performed over the range from 280°C to 480°C at fixed processing conditions of 1.2 keV, 0.5 mA/cm2 and 20 min. Nitrogen content and layer thickness have been determined by nuclear reaction analysis. Structural and micromechanical analyses have been performed by X-ray diffraction and microhardness measurements.

Stickstoffdiffusion in austenitischem Edelstahl unter Hochstrom-Ionenimplantation
Parascandola, S.; Günzel, R.; Grötzschel, R.; Richter, E.; Möller, W.
Abstract
Die Hochstrom-Ionenimplantation von Stickstoff ermöglicht die Aufstickung von Oberflächen bei niedrigen Temperaturen und in kurzen Zeiten. Die Tribologie von austenitischen Edelstählen kann durch diesen Prozeß extrem verbessert werden. Das Diffusionsverhalten von hochstrom-implantiertem Stickstoff in austenitischem Edelstahl wird untersucht. Dazu werden die Stickstoffprofile von 14N und 15N implantierten Proben mit Kernreaktionsanalyse (NRA) bestimmt und die Oberflächen mit Röntgenbeugungsspektroskopie (XRD) auf strukturelle Veränderungen analysiert. Verschiedene Diffusionsszenarien werden diskutiert und auf Konsistenz mit den experimentellen Ergebnissen getestet.
