Chapter 4: Power and particle control (2007)

Loarte, A., Lipschultz, B., Kukushkin, A. S., Matthews, G. F., Stangeby, P. C., Asakura, N., ...

Progress, since the ITER Physics Basis publication (ITER Physics Basis Editors et al 1999 Nucl. Fusion 39 2137-2664), in understanding the processes that will determine the properties of the plasma...

Flux dependence of carbon erosion and implication for ITER (2005)

J. Roth, A. Kirschner, W. Bohmeyer, S. Brezinsek, A. Cambe, E. Casarotto, ...

In a collaboration of eight experiments the dependence of the chemical erosion yield of carbon on the ion flux, U, was established to U #0.54 at high ion fluxes. With this flux dependence a...

LETTER Flux dependence of carbon chemical erosion by deuterium ions (2004)

J. Roth, R. Preuss, W. Bohmeyer, S. Brezinsek, A. Cambe, E. Casarotto, ...

The chemical erosion of carbon in interaction with a hydrogen plasma has been studied in detail in ion beam experiments, and erosion yield values are available as a function of ion energy and surface...

Key ITER plasma edge and plasma–material interaction issues (2003)

Federici,G., Andrew,P., Barabashi,P., Brooks,J., Doerner,R., Geier,A., ...

Some of the remaining crucial plasma edge physics and plasma–material interaction issues of the ITER tokamak are discussed in this paper, using either modelling or projections of experimental...

A universal measurement system for microwave power transistors (2000)

Heymann, P., Doerner, R., Rudolph, M.

We describe a measurement system for model parameter extraction and full characterization of power transistors in frequency and time domain. It provides bias dependent linear S parameters, power...

Scaling of GaInP/GaAs HBT equivalent-circuit elements (1999)

Rudolph, M., Doerner, R., Richter, E., Heymann, P.

In this paper, GalnP/GaAs HBT's equivalent-circuit elements are investigated with respect to their dependence on layout geome-try. A large number of extracted parameters for HBT's of different...

New GaInP/GaAs-HBT large-signal model for power applications (1998)

Rudolph, M., Doerner, R., Heymann, P.

A new GaInP/GaAs HBT model for power applications is presented. It is based on the Gummel-Poon model. Additionally, it accounts for the increase of the thermal resistance at high temperatures and the...

Ubiquitous Animation: An Element-based Concept to Make 3D Animations Commonplace (1997)

Doerner, R., Luckas, V., Spierling, U.

The concept of CASUS Base is sketched: a universal animation elements library allowing everyone to create animations for everything. First results and examples made in an industrial context are shown.

Approaching nonlinear dynamics by studying the motion of a pendulum I: Observing trajectories in state space (1994)

H. Heng, R. Doerner, B. Hübinger, W. Martienssen

.-A phenomenological introduction into concepts of nonlinear dynamics is given. A driven pendulum is used as an appropriate model to demonstrate characteristic features of the dynamics of nonlinear...
