Title: Effects of varying the step particle distribution on a probabilistic transport model

Abstract

The consequences of varying the step particle distribution on a probabilistic transport model, which captures the basic features of transport in plasmas and was recently introduced in Ref. 1 [B. Ph. van Milligen et al., Phys. Plasmas 11, 2272 (2004)], are studied. Different superdiffusive transport mechanisms generated by a family of distributions with algebraic decays (Tsallis distributions) are considered. It is observed that the possibility of changing the superdiffusive transport mechanism improves the flexibility of the model for describing different situations. The use of the model to describe the low (L) and high (H) confinement modes is also analyzed.

  • The transport of particles or heat against the driving gradient is studied by employing a probabilistic transport model with a characteristic particle step length that depends on the local concentration or heat gradient. When this gradient is larger than a prescribed critical value, the standard deviation of the step size is large compared to its value when the gradient is below critical. For symmetric as well as asymmetric off-axis fueling, the model is capable of producing profiles peaking at the axis. Additionally, profile consistency is obtained over a broad range of source strengths. These results supplement recent works by vanmore » Milligen et al. [Phys. Plasmas 11, 3787 (2004)], which applied Levy distributed step sizes in the case of supercritical gradients to obtain the up-gradient transport.« less
  • We extend our probabilistic model of quasielastic particle transport to include possible inelastic scatterings of the particles in the bulk of the studied media. We show that this extended model can be used to describe different types of experiments involving electrons that go through or are reflected by a plane-parallel layer deposited on a substrate. In particular, we reanalyze the experimental results of low-energy ({approx lt}10 eV) electron transmission through solid xenon and solid molecular nitrogen. This analysis shows that the extended model is consistent with the quasielastic one, but is more powerful since we can now determine both themore » elastic and inelastic electron mean free paths. The analysis allows one to study the threshold creation of excitons that can be observed at about 8.5 and 9.5 eV in solid xenon, and around 7.5 eV in solid molecular nitrogen.« less
  • The probabilistic description of quasielastic particle transport given in a previous paper is used to analyze the results of low-energy electron transmission experiments on thin solid xenon and molecular nitrogen films deposited on a metal substrate. Values of the entrance probabilities of the incident electrons at the vacuum-film interface and of the electron scattering mean free paths in the films are extracted in the electron energy range 1.6--7.9 eV for xenon, and 2.4--7.4 eV for molecular nitrogen. The effects of anisotropy in the surface scattering and in the reflections at the two interfaces of the films are also discussed.
  • We present a three-dimensional probabilistic model of particle transport in a medium where the particles suffer quasielastic collisions. The model accounts for bulk and surface scattering, as well as partial reflections at the boundaries of the medium. We give analytical and numerical methods for the evaluation of the particle transmission probability in the case of a medium with a plane-parallel geometry. The influence of the various parameters of the model on this probability is also discussed.
  • In this paper the authors consider the one-dimensional linear Boltzmann equation which describes the time evolution of the spatially uniform distribution f(v,t) of charged particles moving with velocity v [element of] R within a host medium under the influence of a time-varying acceleration field a = a(t). The collision frequency [nu](v) is assumed to be integrable, and the acceleration field is supposed to be such that there exist a constant b > 0 and a number t[sub r] for which [integral][sub t[sub r]][sup +[infinity]][a([rho])[minus]b]d[rho] exists and is finite. This condition on the long time behavior of the acceleration field characterizesmore » the fields giving the same asymptotics of the problem. In other words, the authors prove that under these conditions the asymptotic dynamics of the problem give rise to charged particles that are accelerated indefinitely, i.e. they are in presence of the so-called runaway phenomenon. This result is obtained in the framework of scattering theory, proving the existence of asymptotic wave operators which guarantee that the solution of the time-dependent problem will generate a travelling wave in velocity space with velocity b as t [yields] + [infinity].« less
