Microdosimetry of Very-High-Energy Heavy Ion Beams for Electronics Testing Using Silicon-on-Insulator Detectors
/ Waets, Andreas (CERN ; U. Zurich (main)) ; Emriskova, Natalia (CERN) ; Garcia Alia, Ruben (CERN) ; Klimek, Karolina (CERN) ; Pan, Vladimir (Wollongong U.) ; Rosenfeld, Anatoly (Wollongong U.) ; Tran, Linh T (Wollongong U.) ; Vohradsky, James (Wollongong U.) ; Kok, Angela (SINTEF, Oslo) ; Povoli, Marco (SINTEF, Oslo) et al.
This article explores the use of microdosimetry with
a silicon-on-insulator (SOI) detector for characterizing very-high-
energy (VHE) heavy ion beams used specifically for single event
effect (SEE) testing of electronics. The detector was deployed
at CERN’s heavy ion facility for radiation effects testing and
exposed to lead ion beams in the 100–1000 MeV per nucleon
kinetic energy range. [...]

Geant4 simulation model of electromagnetic processes in oriented crystals for accelerator physics
/ Sytov, Alexei (INFN, Ferrara ; KISTI, Daejeon) ; Bandiera, Laura (INFN, Ferrara) ; Cho, Kihyeon (KISTI, Daejeon) ; Hwang, Soonwook (KISTI, Daejeon) ; Cirrone, Giuseppe Antonio Pablo (INFN, LNS) ; Pandola, Luciano (INFN, LNS) ; Guatelli, Susanna (Wollongong U.) ; Rosenfeld, Anatoly (Wollongong U.) ; Haurylavets, Viktar (Minsk, Inst. Nucl. Problems) ; Tikhomirov, Victor (Minsk, Inst. Nucl. Problems) et al.
Electromagnetic processes of charged particles interaction with oriented crystals provide a wide variety of innovative applications such as beam steering, crystal-based extraction/collimation of leptons and hadrons in an accelerator, a fixed-target experiment on magnetic and electric dipole moment measurement, X-ray and gamma radiation source for radiotherapy and nuclear physics and a positron source for lepton and muon colliders, a compact crystalline calorimeter as well as plasma acceleration in the crystal media. One of the main challenges is to develop an up-to-date, universal and fast simulation tool to simulate these applications. [...]

Gold nanoparticles have demonstrated significant radiosensitization of cancer treatment with x-ray radiotherapy. To understand the mechanisms at the basis of nanoparticle radiosensitization, Monte Carlo simulations are used to investigate the dose enhancement, given a certain nanoparticle concentration and distribution in the biological medium.

The Editorial
/ Rosenfeld, Anatoly (Wollongong U.) ; Silari, Marco (CERN) ; Campbell, Michael (CERN)
This Special Issue is dedicated to Medipix and Timepix semiconductor radiation detectors whose origins lie in the R & D for the semiconductor tracking detectors of the Large Hadron Collider at CERN. The issue covers developments starting with the early idea of photon counting readout first implemented in the Medipix ASIC right up to the advanced Timepix ASICs, and their applications in different fields of science, industry and medicine, stretching all the way from charge particle tracking in High Energy Physics to molecular spectroscopy..
