ABSTRACT In our previous paper [V. Lazurik, V. Moskvin and T. Tabata, IEEE
Trans. Nucl. Sci. 45, pp. 626-31 (1998)] the average depth of electron
penetration, Rav, has been introduced as the average of the
maximum depths on the trajectories of electrons passing through a
target. In the present work the dependence of Rav on the
angle of incidence of an electron beam has been studied. A
semi-empirical equation is derived to calculate Rav as a
function of angle of incidence. We extend the study of Rav
from using it to characterize the average behavior of electron beams in
a target to describing the generation of secondary electrons by photon
beams. It is shown that Rav can be used in a wide variety of
applications in which the characteristic size of the spatial region of
electron production is important

    ABSTRACT: A mixed algorithm for Monte Carlo simulation of relativistic electron and positron transport in matter is described. Cross sections for the different interaction mechanisms are approximated by expressions that permit the generation of random tracks by using purely analytical methods. Hard elastic collisions, with scattering angle greater than a preselected cutoff value, and hard inelastic collisions and radiative events, with energy loss larger than given cutoff values, are simulated in detail. Soft interactions, with scattering angle or energy loss less than the corresponding cutoffs, are simulated by means of multiple scattering approaches. This algorithm handles lateral displacements correctly and completely avoids difficulties related with interface crossing. The simulation is shown to be stable under variations of the adopted cutoffs; these can be made quite large, thus speeding up the simulation considerably, without altering the results. The reliability of the algorithm is demonstrated through a comparison of simulation results with experimental data. Good agreement is found for electrons and positrons with kinetic energies down to a few keV.

    ABSTRACT: The average depth of electron penetration is introduced as the physical quantity useful in electron beam irradiation. It is defined as the average of the maximum depths on the trajectories of electrons passing through finite, semi-infinite or infinite medium. The relation between the transmission coefficient as a function of slab thickness and the distribution of the maximum depths is analyzed, and a semiempirical equation to calculate the average depth of electron penetration is given for 0.1- to 50-MeV electrons incident on materials of atomic numbers from 4 to 92. It is shown that the quantity introduced is usable as the characteristic depths of energy and charge depositions in a target, and can possibly be generalized to the case of heterogeneous targets.

    ABSTRACT: An empirical relation for the transmission coefficient of electrons impinging on aluminum absorbers is given as a function of absorber thickness x, incident energy T0, and angle of incidence θ. It has been formulated by incorporating the dependence upon θ in the empirical equation for the case of normal incidence reported previously by the present authors. Numerical constants in the relation have been determined through least-squares fit to the data for T0 = 0.5−10 MeV generated by the Monte Carlo code of Berger and Seltzer. The rms absolute deviation, evaluated over θ = 0°−75°, of the relation from the Monte Carlo data is about 0.03 in the entire energy region considered.
