A Monte Carlo code for full simulation of a transition radiation detector

A full simulation of a transition radiation detector (TRD) based on the GEANT, GARFIELD, MAGBOLTZ and HEED codes has been developed. This simulation can be used to study and develop TRD for high energy particle identification using either the cluster counting or the total charge measurement method. In this article it will be also shown an application of this simulation to the discrimination of electrons from hadrons in beams of momentum of few GeV/c or less, assuming typical TRD configuration, namely radiator-detector modules.Comment: 14 pages with 12 figure

Unfolding spectral analysis of the Fermi-LAT data

The Large Area Telescope (LAT) onboard the Fermi satellite is observing the gamma-ray sky in the high energy region, above 20 MeV. We have developed a method to reconstruct the energy spectra of the gamma-rays detected by the Fermi LAT instrument based on a Bayesian unfolding approach, that takes into account the energy dispersion introduced by the instrument response. The method has been successfully applied to reconstruct the energy spectra of both steady and pulsating point sources. The analysis technique will be illustrated and the results obtained in some significant test cases will be discussed.Comment: 6 pages, 9 figure
