Light Dark Matter Search with Ionization Signals in XENON1T. [PDF]

Physical Review Letters, 2019
We report constraints on light dark matter (DM) models using ionization signals in the XENON1T experiment. We mitigate backgrounds with strong event selections, rather than requiring a scintillation signal, leaving an effective exposure of (22±3) tonne ...

Hybrid CMP Slurry Supply System Using Ionization and Atomization

Applied 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.

Separation of ions with the same charge to mass ratio from a collision experiment [PDF]

Journal of the Serbian Chemical Society, 2000
Some atomic collision experiments lead to ions having identical q/m ratio, as well as average velocity, so that standard electric and magnetic analyzers are not able to identify them separately.

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

Photonics, 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 ...

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

Atoms, 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

Control of Foodborne Biological Hazards by Ionizing Radiations

Foods, 2020
Ionization radiations are used to ensure food safety and quality. This irradiation process uses ions of beta or gamma rays to inactivate or destroy the food spoilage pests, microorganisms and their toxins without significantly increasing the temperature ...

Triply Differential Positron and Electron Impact Ionization of Argon: Systematic Features and Scaling

Atoms, 2021
Triply differential data are presented for the 200 eV positron and electron impact ionization of argon. Six electron emission energies between 2.6 and 19 eV, and for scattering angles of 2, 3, and 4 degrees cover a momentum transfer range of 0.16 to 0.31

Ionization behavior of nanoporous polyamide membranes

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Novel membrane processes and materials are needed to combat global water scarcity. The advancement of membrane materials for water purification processes such as desalination is hindered by our limited understanding of structure–property ...

Field-ionization threshold and its induced ionization-window phenomenon for Rydberg atoms in a short single-cycle pulse [PDF]

, 2014
We study the field-ionization threshold behavior when a Rydberg atom is ionized by a short single-cycle pulse field. Both hydrogen and sodium atoms are considered. The required threshold field amplitude is found to scale \emph{inversely} with the binding
