abstract = {The knowledge about degradation processes caused by Edge
Localised Modes (ELMs) on plasma facing materials (PFMs) in
future confinement experiments is essential to allow
lifetime estimations for first wall and divertor components.
Electron beam simulations of the occurring heat loads have
the advantage to be able to work at higher frequencies
compared to other experiments (e.g. plasma streams),
allowing a large number of ELM-like heat pulses. This paper
deals with the electron beam guidance method used in the
JUDITH 2 facility in Forschungszentrum Jülich (Germany). As
the beam is described well by a Gaussian profile with a
variable FWHM, depending on several parameters, e.g. vacuum
pressure, the guidance is of special interest in order to
achieve an approximately homogeneous (ELM-like) loading. A
circular pattern turned out to provide advantages, in
particular related to an increased stability against beam
width fluctuations},
