The Italian National Center for Hadrontherapy (CNAO, Centro Nazionale di Adroterapia Oncologica), a synchrotron-based hospital facility, started the treatment of patients within selected clinical trials in late 2011 and 2012 with actively scanned proton and carbon ion beams, respectively. The activation of a new clinical protocol for the irradiation of uveal melanoma using the existing general-...

The Geant4 toolkit was used to perform benchmark Monte Carlo simulations of proton micro-tomography imaging. A phantom an inertial confinement fusion (ICF) target designed, based on experimental data. Simulations STIM (Scanning Transmission Ion Microscopy) and PIXE (Particle Induced X-ray Emission) tomography were performed. Quantitative images obtained from the TomoRebuild JPIXET software pack...

Introduction: Microdosimeters are helpful for dose equivalent measurement in unknown radiation fields. The favorable physical and mechanical properties of the detector-grade chemical vapor deposition diamond materials have made the diamond microdosimeters suitable candidate for radioprotection applications in space. The purpose of this work is the investigation of the dose equivalent response o...

Abstract The estimate of the total electron yield is fundamental for our understanding test-mass charging associated with cosmic rays in Laser Interferometer Space Antenna (LISA) Pathfinder mission and forthcoming gravitational wave observatory LISA. To unveil role low energy electrons this process owing to galactic solar energetic particle events, work we study interaction keV sub-keV a gold s...

A main goal of current low background physics is the search for rare and novel phenomena beyond Standard Model particle physics, e.g. scattering off a potential Dark Matter inside CaWO _4 4 crystal or neutrinoless double beta decay Ge nucleus. The success such sea...

The Geant4 physics lists package encompasses predefined selections of physics processes and models to be used in simulation applications. Limited documentation is available in the literature about Geant4 pre-packaged PhysicsLists and their validation. The reports in the literature mainly concern specific use cases. This paper documents the epistemological grounds for the validation of Geant4 pr...

End users run GEANT4 executable les customized and provided by application programmers. GAG (GEANT4 Adaptive GUI) is a GUI for them to run GEANT4 by using commands and by changing associated parameters. We have two implementations of GAG, that is, Tcl/Tk and Java versions. GAG provides them with a tree (Java) or Pull-down menu (Tcl/Tk) of commands, a widget of parameter inputs of variable forma...

The performance of a large-scale water Cherenkov neutrino telescope relies heavily on the transparency surrounding water, quantified by its level light absorption and scattering. A pathfinder experiment was carried out to measure optical properties deep seawater in South China Sea with light-emitting diodes (LEDs) as sources, photon multiplier tubes (PMTs) cameras sensors. Here, we present an s...

Introduction: Rectal and bladder cancer are the most common disease among young man. Although External Radiotherapy (EBRT) is one of the most effective treatment options introduced so far, the testis undesired radiation dose increases the risk of infertility and hormonal malfunctioning. The testicles are usually outside of the radiation field, but they can be exposed either to ...
