Calorimetric measurement of electron energy deposition in extended media. Theory vs experiment

Abstract

2. Many of the results were obtained by using Infinite rather than semi-Infinite geom etries. This was done either to simplify the measurement or to facilitate compari son with Spencer's early calculations. In any case, the semi-infinite geometry is of more practice! importance, 3. In the caae of semi-Infinite geometries, there are very little data for electron energies leas than 1.0 MeV for nonnormal incidence, and for multlalab media, 4. Spatial resolution near the surface of aemi-Infinite geometries Is poor, especially for hlgh-atomic-numbcr media. 0,3 a.4 as a* FRACTION OF A ftCAIf RANGE Figure 1.1, Comparison of Experimental Measurements and Theoretical Predictions of Energy Deposition Profiles in Seml-Infinlte Aluminum by Normally Incident 0. 5-MeV Electrons

The performance of the geant4 standard EM package for LHC and other applications

“…The new test [20] has been developed for the comparisons with the SANDIA laboratory data [21] to control on electron transport simulation in different materials. This is a complimentary independent validation important as to EM calorimetry and for simulation of particle detectors.…”

GEANT4 simulation of electron energy deposition in extended media

“…The effective use of electron beams therefore requires information about the modification of the energy spectrum of the beam resulting from multiple Coulomb scattering in foil and the total energy loss. This paper presents the results of a comparison of GEANT4 electromagnetic models with respect to the reference data of the SANDIA National Laboratories [6]. Notice that the standard data set of SANDIA was used for validating Monte Carlo simulation codes for many years, especially the GEANT4 toolkit.…”

Telematics-based online client–server/client collaborative environment for radiotherapy planning simulations

“…To validate the PMCEPT code, we have performed extensive benchmark tests by comparing the PMCEPT results with absolute calorimetric dose measurements [13] for low kinetic energies of electron beams incident on homogeneous and multilayered media and with EGS4 [16] and DPM [22] codes for high-energy electron beams that irradiate homogeneous and heterogeneous phantoms. The detailed benchmark results appear in reference 7.…”
