  The ExB electron drift instability, present in many plasma devices, is an
important agent in cross-field particle transport. In presence of a resulting
low frequency electrostatic wave, the motion of a charged particle becomes
chaotic and generates a stochastic web in phase space. We define a scaling
exponent to characterise transport in phase space and we show that the
transport is anomalous, of super-diffusive type. Given the values of the model
parameters, the trajectories stick to different kinds of islands in phase
space, and their different sticking time power-law statistics generate
successive regimes of the super-diffusive transport.
