Monte Carlo-based Investigation of Absorbed-dose Energy Dependence of Thermoluminescent Dosimeters in Therapeutic Proton and Carbon Ion Beams

Journal of Medical Physics
Background: The present study is aimed at calculating relative absorbed-dose energy response correction (R) of commonly used thermoluminescent dosimeters (TLDs) such as LiF, Li2B4O7, and Al2O3 as a function of depth in water for protons (50–250 MeV/n ...

Influence of photon, proton and carbon ion irradiation on differentiation, maturation and functionality of dendritic cells

Frontiers in Bioscience-Scholar, 2022
While the primary purpose of radiotherapy (RT) is the elimination of cancer cells by inducing DNA-damage, considerable evidence emerges that anti-neoplastic effects extend beyond mere tumor cell killing. These secondary effects are based on activation of

Rapidity dependence of deuteron production in Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV

, 2011
We have measured the distributions of protons and deuterons produced in high energy heavy ion Au+Au collisions at RHIC over a very wide range of transverse and longitudinal momentum.

Study of light ions acceleration in a diode with a solid target and registration of nuclear proton-boron reaction products generated in the plasma diode [PDF]

Ядерна фізика та енергетика
The results of proton fluxes registration and the nuclear reactions (p + 11B > 3α) they induce on boron-containing targets in a plasma diode pinch, generated by irradiation of the anode target with a relativistic electron beam, are presented.

Evaluation of Histone Deacetylase Inhibitors as Radiosensitizers for Proton and Light Ion Radiotherapy

Frontiers in Oncology, 2021
Significant opportunities remain for pharmacologically enhancing the clinical effectiveness of proton and carbon ion-based radiotherapies to achieve both tumor cell radiosensitization and normal tissue radioprotection.

Interactions of UHE cosmic ray nuclei with radiation during acceleration: consequences on the spectrum and composition [PDF]

, 2009
In this paper, we study the diffusive shock acceleration of cosmic-ray protons and nuclei, taking into account all the relevant interaction processes with photon backgrounds.

The first cosmic ray albedo proton map of the Moon [PDF]

, 2012
[1] Neutrons emitted from the Moon are produced by the impact of galactic cosmic rays (GCRs) within the regolith. GCRs are high-energy particles capable of smashing atomic nuclei in the lunar regolith and producing a shower of energetic protons, neutrons

Proton-air and proton-proton cross sections [PDF]

EPJ Web of Conferences, 2013
Different attempts to measure hadronic cross sections with cosmic ray data are reviewed. The major results are compared to each other and the differences in the corresponding analyses are discussed. Besides some important differences, it is crucial to see that all analyses are based on the same fundamental relation of longitudinal air shower ...
