Abstract. Alfvén eigenmodes (AEs) excited by fusion born α particles can degrade the heating efficiency of a burning plasma and throw out αs. To experimentally study the effects of excitation of...

Alfvén eigenmodes (AEs) excited by α particles in a burning plasma can degrade the heating efficiency by spatial redistribution of the resonant α particles. Changes of the orbit invariants in...
On the Dynamics of Alfvén Eigenmode Excitation (2008)
K. Holmström, T. Bergkvist, T. Hellsten
Alfvén eigenmodes (AEs) excited by fast ions can cause losses of fast ions in thermonu-clear experiments. To describe the dynamics of the AE excitation, it is necessary to include the decorrelation...
ON BOCHNER-KRALL ORTHOGONAL POLYNOMIAL SYSTEMS (2007)
T. Bergkvist, H. Rullg Ard, B. Shapiro
Abstract. In this paper we address the classical question going back to S. Bochner and H. L. Krall (see original [B], [Kr] and [EKLW] for the modern status quo) to describe all systems fpn (x)g
