Recent progress in the development of a solar neutron tracking device (SONTRAC) [PDF]

, 1999
We report the results of recent calibration data analysis of a prototype scintillating fiber tracking detector system designed to perform imaging, spectroscopy and particle identification on 20 to 250 MeV neutrons and protons.

End-to-End Event Classification of High-Energy Physics Data

Journal of Physics: Conference Series, 2018
Feature extraction algorithms, such as convolutional neural networks, have introduced the possibility of using deep learning to train directly on raw data without the need for rule-based feature engineering.

Assessing proton plans with three different beam delivery systems versus photon plans for head and neck tumors

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose To compare plan quality among photon volumetric modulated arc therapy (VMAT) and intensity‐modulated proton therapy (IMPT) with robustness using three different proton beam delivery systems with various spot size (σ) ranges: cyclotron‐generated proton beams (CPBs) (σ: 2.7–7.0 mm), linear accelerator proton beams (LPBs) (σ: 2.9–5.5 mm),

Machine learning uncertainties with adversarial neural networks

European Physical Journal C: Particles and Fields, 2019
Machine Learning is a powerful tool to reveal and exploit correlations in a multi-dimensional parameter space. Making predictions from such correlations is a highly non-trivial task, in particular when the details of the underlying dynamics of a ...

Simulation of Cosmogenic Neutrino Spectra with the GZKFast Event Generator [PDF]

arXiv, 2007
GZKFast is a low-cost astrophysical event generator designed to simulate photohadron processes resulting from ultra high energy cosmic ray fluxes. GZKFast is an easy to use event generator which specifically addresses issues relevant to cosmogenic neutrinos and the ultra high energy (UHE) neutrino spectrum.

Evaluation of the dose reduction effect of crystalline lens exposure in cone‐beam computed tomography with bismuth eye shield for image‐guided radiation therapy: An anthropomorphic phantom study

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract This study aimed to evaluate the dose‐exposure reduction effect of a crystalline lens with a bismuth eye shield using cone‐beam computed tomography (CBCT) for head image‐guided radiation therapy. The ocular surface dose of the head phantom (THRA‐1) is defined as a crystalline lens exposure dose and is measured using a radiophotoluminescence ...

Two-particle angular correlations in pp collisions recorded with the ALICE detector at the LHC

EPJ Web of Conferences, 2014
We report on the studies of two-particle angular correlations measured in proton-proton collisions at a center-of-mass energy of √s = 7 TeV recorded by ALICE at the LHC.

Event-by-Event Identified Particle Ratio Fluctuations in Pb-Pb Collisions with ALICE using the Identity Method [PDF]

, 2015
The study of event-by-event fluctuations of identified hadrons may reveal the degrees of freedom of the strongly interacting matter created in heavy-ion collisions and the underlying dynamics of the system. The observable $\nu_{dyn}$, which is defined in terms of the moments of identified-particle multiplicity distributions, is used to quantify the ...

Theoretical Directional and Modulated Rates for Direct SUSY Dark Matter Detection

, 2002
Exotic dark matter together with the vacuum energy (cosmological constant) seem to dominate in the flat Universe. Thus direct dark matter detection is central to particle physics and cosmology.
