چکیده
A set of physics processes has been developed in the Geant4 Simulation Toolkit to describe the electromagnetic interactions of photons and electrons with matter down to 250 eV. Preliminary comparisons of the models with experimental data show a satisfactory agreement.

متن کاملMonte Carlo Simulations of X-ray Generation and Detection
The employment of Monte Carlo simulations in the applied nuclear physics techniques has increased with the data processing capabilities of the commercial personal computers. Since the inclusion of the low-energy electromagnetic interactions in GEANT4, this Monte Carlo simulation toolkit has produced results which reveal its promising utilization in radiation dosimetry, radiation protection and ...
متن کاملThe CMS Lead Tungstate Electromagnetic Calorimeter
The CERN LHC will open a new regime in the exploration of fundamental interactions. Of central importance to these studies will be the precise measurement of high energy electrons and photons. The CMS experiment therefore incorporates a high resolution electromagnetic calorimeter comprising 76000 lead tungstate crystals, covering almost 4pi, and capable of operating reliably for ten years in a ...
متن کاملModeling the relativistic runaway electron avalanche and the feedback mechanism with GEANT4
This paper presents the first study that uses the GEometry ANd Tracking 4 (GEANT4) toolkit to do quantitative comparisons with other modeling results related to the production of terrestrial gamma ray flashes and high-energy particle emission from thunderstorms. We will study the relativistic runaway electron avalanche (RREA) and the relativistic feedback process, as well as the production of b...
متن کاملEvaluation of Monte Carlo tools for high energy atmospheric physics
The emerging field of high energy atmospheric physics (HEAP) includes terrestrial gamma-ray flashes, electron–positron beams and gamma-ray glows from thunderstorms. Similar emissions of high energy particles occur in pulsed high voltage discharges. Understanding these phenomena requires appropriate models for the interaction of electrons, positrons and photons of up to 40 MeV energy with atmosp...
