AB  - The transmission of low-energy electrons through a macroscopic steel capillary has been investigated both experimentally and theoretically. The length of the steel capillary was L = 19.5 mm and the inner diameter was d = 0.9 mm. The kinetic energy distribution of electrons transmitted through the steel capillary was recorded for a tilt angle of psi = 2.6 degrees of the incident electron beam with respect to the capillary axis. Accompanying simulations based on classical transport theory reproduce the experimental data to a high degree of agreement. Transmission for other tilt angles has also been simulated to investigate the influence of the tilt angle on the guiding efficiency.

AB  - The backscattered electron spectra from graphite sample were studied both experimentally and theoretically at impact energies between 500 and 5000 eV. The angle of the incident electron beam was 50° and the detection angle was 0° with respect to the surface normal, respectively. Monte Carlo (MC) simulations were performed based on the Classical Transport Theory (CTT) model to mimic the experimental spectra. In our simulations, both elastic and inelastic scattering of primary electrons and secondary electron emission from graphite are taken into account. There is found satisfactory agreement between measured and calculated electron spectra. © 2018 Elsevier B.V.

AB  - We present Monte Carlo simulation of low energy electrons backscattered from iron (Fe) surface. We take into account both elastic and inelastic collisions during the simulation. In our simulations the primary electron energy is 150 eV and the incidence angle of the electron beam with respect to the surface is varied between 1 degrees and 90 degrees. The backscattered electron energy loss distributions for primary and as well for secondary electrons and the distribution of maximum electron penetration depths in the Fe sample were calculated using only the bulk and also the surface dielectric function.

AB  - We have measured 200 eV electron transmission through a single platinum tube of a diameter of 3.3 mm. We find that the transmission of electrons can be detected even at large tilt angles, where the tube is not transparent geometrically. The transmission drops down exponentially with increasing the tilt angle. The energy spectrum of detected electrons behind the tube contain contributions at lower energies due to both inelastic scattering and secondary electron emission. The spectrum is qualitatively in good agreement with the calculations performed for the flat Pt surface in order to understand and model the electron interaction processes that define the transmission and the energy spectrum at the exit.

AB  - We present Monte Carlo simulation of low energy electrons backscattered from platinum (Pt) surface. We take into account both elastic and inelastic collisions during the simulation. For the case of the elastic scattering of electrons by Pt atoms we use the static field approximation with non-relativistic Schrodinger partial wave analysis. For the case of inelastic scattering we use the dielectric response formalism. In our simulations the primary electron energy is 250 eV and the incidence angle of the electron beam with respect to the surface is varied between 1 degrees and 90 degrees. The backscattered electron energy loss distributions for primary and as well for secondary electrons and the distribution of maximum electron penetration depths in the Pt sample were calculated using only the bulk and also the surface dielectric function. We found that the maximum attained depth of the electrons is around 20 angstrom, i.e. the electrons are at the vicinity of the surface. Therefore we expect that the experimental data will be close to our simulation using surface-excitations modes. (C) 2014 Elsevier B.V. All rights reserved.
