Detector simulation

Oral

The status of the Geant4 electromagnetic physics sub-libraries is presented. Current developments of electromagnetic physics is focused on implementation of next to leading terms of various electromagnetic processes including multiple and single scattering, gamma conversion, positron annihilation. Atomic de-excitation module is use in several electromagnetic models and in radioactive decay....

Detector simulation

Oral

Precise experimental knowledge on a wide variety of observables is a key ingredient for improving our understanding of nuclear structure. As a result, each new generation of accelerator facilities produces larger amounts of data than the previous generation in order to improve the precision of the measurements. Hence, more advanced analysis tools are required to deal with these large amounts...

Detector simulation

Oral

In order to fully explore the particle identification and measurement capability of the telescopes built from two or more silicon strip detectors, one has to calculate all the dead layers of the detectors as well as the calibration coefficients for each channel. The most reliable way of solving this problem is to combine various measurements with calibration sources and detailed Monte Carlo...

Detector simulation

Oral

Crystals have an internally ordered structure resulting in anisotropy of electromagnetic interaction of charged particles with crystals. When particles move along crystal axes or planes, they can oscillate in their electric field.
For ultra-relativistic particles, i.e. ten or hundred GeV electrons and positrons the electric field of axes or planes is comparable to the Schwinger critical field...

3. Characterization of CsI(Tl) and LYSO(Ce) detectors scintillators and validation with MCNPX and GEANT4 codes.

ABSTRACT

The Monte Carlo method is used to calculate the photon detection efficiency of scintillator detectors exposed to gamma rays in the energy range of 59.5 KeV to 1274.54 KeV. This work aims at calculating the response functions for two scintillation detectors CsI(Tl) and LYSO(Ce) (Lu1.9Y0.1SiO5:Ce0.5%) of size 10x10x5 mm3, to gamma-ray sources up to 1274.54 keV. Both detectors were...

29. A simulation model for reproduction of the background radiation flash produced by high energetic H-like ions during their stopping in matter: I. The contribution of the electron capture processes - Radiative Electron Capture and Primary Bremsstrahlung.

Mr Pavel Detistov

Detector simulation

Oral

The background radiation flash produced by stopping of ions in matter is a main obstacle for detection of lower energy gamma-rays transitions emited by short-lived excited states in unstable nuclear systems obtained in experiments with relativistic ion beams. The large number of produced X-rays blinds the detectors and their pile-up in the detector’s crystal volume may change the profile of...
