Impact of cosmic rays and solar energetic particles on the Earth’s ionosphere and atmosphere

open access: yesJournal of Space Weather and Space Climate, 2013
A brief review of the study during COST Action ES0803 of effects due to cosmic rays (CR) and solar energetic particles (SEP) in the ionosphere and atmosphere is presented.

Hybrid CMP Slurry Supply System Using Ionization and Atomization

open access: yesApplied Sciences, 2021
Chemical mechanical planarization (CMP) is frequently used in semiconductor manufacturing to polish the surfaces of multiple layers in a wafer. The CMP uses a slurry that aids in fabricating a smooth surface by removing the excess materials.

Picosecond ionization dynamics in femtosecond filaments at high pressures [PDF]

open access: yes, 2017
We investigate the plasma dynamics inside a femtosecond-pulse-induced filament generated in an argon gas for a wide range of pressures up to 60 bar. At higher pressures, we observe ionization immediately following a pulse, with up to a threefold increase

Differential Analysis of the Positron Impact Ionization of Hydrogen in Debye Plasmas

open access: yesAtoms, 2023
In this work, a theoretical differential analysis of the positron impact ionization of hydrogen embedded in weakly coupled plasmas at an impact energy of 80 eV is developed.

Intensity-Resolved Above Threshold Ionization of Xenon with Short Laser Pulses [PDF]

open access: yes, 2014
We present intensity-resolved above threshold ionization (ATI) spectra of xenon using an intensity scanning and deconvolution technique. Experimental data were obtained with laser pulses of 58 fs and central wavelength of 800 nm from a chirped-pulse ...

Dichroism Effects in the Ionization of Polarized Atoms by Short Circularly Polarized Laser Pulses

open access: yesPhotonics, 2023
The dichroism effects, i.e., asymmetries of the ionization probability with respect to the inversion of either the atomic orientation (magnetic dichroism, MD) or the circular polarization degree of the photon beam (circular dichroism, CD), are ...

The different origins of high- and low-ionization broad emission lines revealed by gravitational microlensing in the Einstein cross [PDF]

open access: yes, 2016
We investigate the kinematics and ionization structure of the broad emission line region of the gravitationally lensed quasar QSO2237+0305 (the Einstein cross) using differential microlensing in the high- and low-ionization broad emission lines.

Ambient Ionization Mass Spectrometry: Recent Developments and Applications.

open access: yesAnalytical Chemistry, 2019
The early 2000s brought a new age in the field of mass spectrometry (MS) with the introduction of ambient ionization MS techniques. As defined by one of its early visionaries, Prof. R.

Interference Effects in Fully Differential Ionization Cross Sections near the Velocity Matching in P + He Collisions

open access: yesAtoms, 2022
We performed a fully differential experimental and theoretical study on ionization of He in intermediate-energy collisions with protons for a small projectile coherence length. Data were taken for an ejected electron energy corresponding to a speed close
