A Sonic Jet Corona Ionizer for Electrostatic Discharge and Aerosol Neutralization [PDF]

open access: yesAerosol Science and Technology, 1994
A sonic jet bipolar ionizer has been designed and tested. Ion production rates and characteristics of particulate contaminants were studied as a function of design parameters (i.e., electrode material, and orifice plate material) and of operating conditions (i.e., electrode to orifice distance, pressure, electrode voltage).

Neutralization by a Corona Discharge Ionizer in Nitrogen Atmosphere

open access: yesIEEJ Transactions on Fundamentals and Materials, 2009
AbstractElectrostatic neutralization of multilayer‐loading silicon wafers is demonstrated using a corona discharge ionizer in a nitrogen atmosphere, where AC and DC voltages are applied to two needle electrodes for generation of negative‐ and positive‐charged particles, respectively.

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 27-82., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Effect of transverse airflow on the deflection of negative corona discharge on the Trichel pulse mode at atmospheric pressure

open access: yesAIP Advances, 2021
Negative corona discharge can deflect in transverse airflow in pin-to-plane electrodes at atmospheric pressure. In this paper, we investigate the mechanism of Trichel pulse discharge deflection in transverse airflow and give a further understanding of ...
