The impact of fusion-born alpha particles on runaway electron dynamics in ITER disruptions

Nuclear Fusion, 2023
In the event of a tokamak disruption in a D-T plasma, fusion-born alpha particles take several milliseconds longer to thermalise than the background. As the damping rates drop drastically following the several orders of magnitudes drop of temperature ...

Radioluminescence yield of alpha particles in air

New Journal of Physics, 2014
Alpha particles can be detected by measuring the radioluminescence light which they induce when absorbed in air. The light is emitted in the near ultraviolet region by nitrogen molecules excited by secondary electrons.

Response of 4H-SiC Detectors to Ionizing Particles

Crystals, 2020
We report the response of newly designed 4H-SiC Schottky barrier diode (SBD) detector prototype to alpha and gamma radiation. We studied detectors of three different active area sizes (1 × 1, 2 × 2 and 3 × 3 mm2), while all detectors had the same 4H-SiC ...

Response of gadolinium doped liquid scintillator to charged particles: measurement based on intrinsic U/Th contamination

, 2018
A measurement is reported for the response to charged particles of a liquid scintillator named EJ-335 doped with 0.5% gadolinium by weight. This liquid scintillator was used as the detection medium in a neutron detector.

Influence of Different Types of Radiation on the Crystal Structure of Silicon Monocrystals n-Si

East European Journal of Physics
In this work, the influence of alpha particles, protons and gamma rays on the crystal structure and structural characteristics of n-type silicon (n-Si) single crystals was studied using X-ray diffraction.

Characterization of Surface α-Particle Radiation, Internal Traceability and Simulation of Typical Tin Spheres

Applied Sciences
Surface α-particle emissivity testing and spectral characterization of two leaded tin spheres (Sn10%Pb90%, Sn63%Pb37%) and one lead-free tin sphere (Sn96.5%Ag3.0%Cu0.5%, SAC305) were carried out.

Orientational Ordering in Athermally Sheared, Aspherical, Frictionless Particles

, 2019
We numerically simulate the uniform athermal shearing of bidisperse, frictionless, two dimensional spherocylinders and three dimensional prolate ellipsoids. We focus on the orientational ordering of particles as an asphericity parameter $\alpha\to 0$ and

Breit Hamiltonian and QED Effects for Spinless Particles [PDF]

, 2001
We describe a simplified derivation for the relativistic corrections of order $\alpha^4$ for a bound system consisting of two spinless particles. We devote special attention to pionium, the bound system of two oppositely charged pions.
