NAG scientific software available at IPP - An introduction to algorithmic differentiation to compute exact and cheap derivatives

ASDEX Upgrade Seminar
Viktor Mosenkis: The IPP site wide license covers the usage of the NAG Numerical Libraries and of the NAG Fortran Compiler on any Linux and on any Solaris system by all researchers and people working at IPP. This presentation will give detailed information about the technical benefits of the NAG scientific software and will explain how people at IPP can have access to it and easily use it. An update on the recent new products and features will also be given. .The NAG Numerical Libraries come with more than 1600 robust and performing mathematical and statistical algorithms to help quickly building high quality numerical models, simulations and applications for data analysis. NAG's algorithms can be used directly from most popular programming languages and development environments including Fortran, C/C++, MATLAB, Python, Java, R, C#/.NET, Excel/VB, Delphi, CUDA, etc. .The NAG Fortran Compiler is known to be the best in the world for error checking and for its high compliance with the Fortran standards so this makes it the compiler of choice to produce clean Fortran code. François Cassier: Understand the basics of Algorithmic Differentiation and how to use this technique to compute exact derivatives and speed up the computational methods of solving large problems. You will .See what constitutes Algorithmic Differentiation (AD) techniques .Understand key theoretical uses for sensitivities, optimization and other solvers .Learn why AD can help you to improve accuracy and performance of your derivative computation .See some of the toolsets that can help you access AD .Hear about some of the issues around using AD [mehr]

SIMNRA is widely adopted by the scientific community of ion beam analysis for the simulation and interpretation of nuclear scattering techniques for material characterization. Taking advantage of its recognized reliability and quality of the simulations, MultiSIMNRA is a computer program that uses multiple parallel sessions of SIMNRA to perform self-consistent analysis of data obtained by different ion beam techniques and/or different experimental conditions of a given sample. In this presentation I will show the basic principle of MultiSIMNRA and a few examples of use. [mehr]

Deuterium migration in erbium oxide coating for tritium permeation barrier

A ten-year study on erbium oxide coating in collaboration with IPP is reviewed. Hydrogen isotope diffusion, solution, and permeation behaviors have been elucidated through experimental and computational approaches. Recent progress will be also introduced in the presentation. [mehr]
The blistering and near-surface deuterium retention of Y2O3-doped W and two different pure W grades were studied after exposure to deuterium (D) plasma at elevated temperatures (370, 450 and 570 K) in PlaQ. The research shows blistering and deuterium retention were strongly dependent on the implantation temperature. In addition, blistering was sensitively influenced by the used tungsten grade, although the total amount of retained D measured by nuclear reaction analysis was comparable. Among the three different investigated tungsten grades, Y2O3-doped W exhibited the lowest degree of surface modification despite a comparable total D retention. [mehr]

Design of a laboratory scale device for centrifugal infiltration of cylindrical tungsten fibre preforms with copper

Wall Forum
Within the present work, a device for manufacturing tungsten fiber reinforced copper metal matrix composite pipes by means of centrifugal infiltration has been designed and tested. Such composite pipes are of direct interest with regard to application as advanced heat sinks in highly loaded plasma facing components due to their high thermal conductivity and considerable material strength. Particularly, the approach for the design, analytical calculations, FEM simulations and the detailed design using CAD is presented. [mehr]

Electromagnetic interference from ICRF - some hints for diagnostic hardening

ASDEX Upgrade seminar: ASDEX Upgrade Seminar
Abstract:This presentation focuses on a real-life problem in the daily operation of plasma diagnostics. Due to the co-existence of high-power heating systems in the MW range and diagnostic equipment sensitive on the microwatt to milliwatt level in the torus hall, electromagnetic interference (EMI) is a critical issue. Taking ICRF heating as an example of an EMI source, a few pratical design guidelines will be presented which have been found to be effective in preventing EMI from affecting diagnostic signals. In addition, the DCN interferometer will serve as an example that later EMI hardening of an existing diagnostic that is not compliant with these design guidelines can be a long-lasting project that involves many steps by trial and error.The talk intends to provide diagnosticians with hints on EMI-resistant electronics design, and to initiate the discussion on how to continue the EMI hardening efforts on the interferometer.

Dynamics and statistics of weather and climate

Institutskolloquium
While the dynamics of the atmosphere can be described by model equations which are derived from first principles, the climate is ruled by feedback loops many of which are known only on a phenomenological level. Irrespective of the foundations of the model, both weather and climate are chaotic: their evolution depends sensitively on initial conditions and on control parameters. Therefore, predictions by modeling are usually complemented by the analysis of empirical data and their extrapolation into the future. In this talk, we present some relevant aspects of model based and statistical forecasting of weather and climate. Although the quality of the weather forecast for most of us is just an issue of convenience, I will discuss the possibility for a strict limit to the number of days ahead for which weather forecast can be successful. More relevant, a clear prediction of how climate will change will be crucial for mitigation and adaptation strategies, which have to be implemented in due time. Climate change goes along with changes in the dynamics, visible through the change of frequency of different regional weather patterns and in the meandering of the jet stream. Predictions here suffer from large time scales of relaxation and of exploration of the phase space, as we will exemplify for the warming trend in Germany. [mehr]

Zeigt uns Star Trek die Energieversorgung der Zukunft?

Institutskolloquium
Wenn das Raumschiff Enterprise zu fremden Planeten reist, benötigt es dafür eine exorbitante Menge an Energie. Wie wird diese Energie erzeugt bzw. gespeichert? Wie funktionieren die Fusionsreaktoren und der Warp-Reaktor an Bord der Enterprise und wie der Impuls- und der Warp-Antrieb? Welche Visionen hatten die Star Trek-Autoren bzgl. der Energieversorgung von Kleingeräte wie Tricorder, Phaser oder dem Kommunikator? Ein Vergleich zu heutigen Technologien macht deutlich, dass wir noch weit von den Möglichkeiten der Energiespeicherung, wie sie bei Star Trek gezeigt wird, entfernt sind. [mehr]
