abstract = {In the reversed-field pinch (RFP) edge, measured transport
and flows are strongly influenced by magnetic islands
(Vianello 2013 Nucl. Fusion 53 073025). In fact, these
islands determine a differential radial diffusion of
electrons and ions which, interacting with the wall, give
rise to a characteristic edge ambipolar potential. Such
island structures also arise in tokamak plasmas, when
resonant magnetic perturbations (RMPs) are applied for
control of edge-localized modes. They impose a
characteristic modulation to edge electron density and
temperature fields, in close correlation with the local
magnetic vacuum topology (Schmitz 2012 Nucl. Fusion 52
054001). In order to develop a generic picture of particle
transport with magnetic islands located in the plasma edge
between RFPs and tokamaks with RMP, test-particle transport
simulations are done on TEXTOR with the same tool used in
RFX-mod, namely, the guiding-centre code ORBIT (White and
Chance 1984 Phys. Fluids 27 2455–67). A typical TEXTOR
discharge in the (m, n) = (12, 4) configuration is
reconstructed and analysed with ORBIT. We use Poincaré and
connection length analysis of electrons and ion orbits to
analyse the magnetic structure taking into account the
different gyro-orbits of both constituents. Density
distributions of test ions and electrons are calculated and
used to obtain an initial estimate of the plasma potential
and radial electric field around the island.},
