Dosimetry of ¹²⁵Iodine protons for in vivo mouse irradiation study
The biological effects of acute, high doses of radiation are well understood. However, the effects of chronic, low doses are not as clear. Mice irradiation experiments to study the correlation of biological effects with chronic low dose rates are underway in order to make conclusions about the …

Development of Lineal Energy Spectrum-Based Biological Effects Models for Protons
… spectra (specifically, lineal energy) for protons. SuperTrack, a GPU-accelerated tool for calculation of microdosimetric spectra was developed and is capable of computing lineal energy spectra up to 5000x faster than using Geant4 directly. Proton lineal energy spectra generated by …

Polarization in the elastic scattering of protons from carbon and nitrogen
"The polarization of protons elastically scattered from nitrogen and carbon has been measured using double scattering techniques 0 The polarization was determined for nitrogen at a scattering angle of 48°c .mo in the proton energy interval 7.6 to 11.8 MeV. The polarization from carbon '~as …

Quasifree knockout of charged particles from ⁴He with 100 MeV protons
… (p,pt) and (p,ph) at 100 MeV. The primary protons were measured at two angles, 45° and 60°, in coincidence with secondary protons, deuterons, tritons or helions covering a wide range of angles on the opposite side of the beam, from -15° to -90° in plane, and from 0° to 30° out-of-plane. The …

Protons and Potentials: How Neurotransmission Influences and is Influenced by pH Transients
Protons, hydrogen ions, are essential to biological functions, contributing to energy metabolism, protein transport, protein modulation, and ion homeostasis. While usually tightly controlled by systemic and cellular processes, free hydrogen ions can overwhelm endogenous buffering during …

Energy relaxation in disordered insulators irradiated by ultrafast protons: a multiscale approach
… insulators irradiated with a burst of ultrafast protons using a multiscale approach. We begin with a phenomenological extension of the two-temperature model, which characterises the relaxation using two time-scales; a rapid electron-phonon relaxation rate and a longer "chemical" relaxation rate …

Dosimetry calibration for low-energy protons produced in the ECU accelerator laboratory
Large doses of ionizing radiation are routinely employed in radiation therapy to destroy malignant tumor cells. Among the available modalities, proton and heavy-ion beams produced by particle accelerators have been widely recognized as highly effective techniques for cancer treatment. A key …
