The evolution of electron overdensities in magnetic fields [PDF]

open access: yes, 2009
When a neutral gas impinges on a stationary magnetized plasma an enhancement in the ionization rate occurs when the neutrals exceed a threshold velocity. This is commonly known as the critical ionization velocity effect.

The Atmospheric Influence on Cosmic-Ray-Induced Ionization and Absorbed Dose Rates

open access: yesUniverse, 2023
When high-energy particles originating from space penetrate the atmosphere, they may interact with atoms and molecules, initiating air showers composed of secondary and tertiary particles propagating towards the ground.

The MICE Muon Beam on ISIS and the beam-line instrumentation of the Muon Ionization Cooling Experiment [PDF]

open access: yes, 2012
The international Muon Ionization Cooling Experiment (MICE), which is under construction at the Rutherford Appleton Laboratory (RAL), will demonstrate the principle of ionization cooling as a technique for the reduction of the phase-space volume occupied

Core-Ionization Spectrum of Liquid Water

open access: yes, 2023
We present state-of-the-art calculations of the core-ionization spectrum of water. The values of experimentally derived solvation shifts in the core 1sO ionization energy of water vary from -1.3 to -2.8 eV due to difficulties in assessing the effect of ...

Burns by Ionizing and Nonionizing Radiation

open access: yesJournal of Burn Care & Research, 2020
Abstract This article consists of the study and investigative analysis of the effects of burns by radiation in humans. Cases of nuclear accidents, such as Chernobyl (ionizing radiation) and the effects of nonionizing radiation, such as infrared and microwave radiation are detailed here.

Nonlinear optical mode coupling by ionization in an Ar-filled capillary with high-power short-pulse excitation [PDF]

open access: yes, 2009
High-power ultrashort laser pulses at near-infrared wavelengths propagating in gas-filled capillaries can form a compact source of XUV/soft X-ray radiation by high-harmonic generation (HHG) [1].
