Editorial: Plasma and related sciences: experimental and theoretical approaches

Résumé

Editorial on the Research Topic. Plasma physics is one of the most important tools for explaining our universe and is extensively used 7 in engineering, industry, medicine, and agriculture to improve the standard of living. Recently, cold 8 atmospheric plasma (CAP) has attracted significant attention due to its ability to generate a cocktail of 9 reactive oxygen species (ROS), reactive nitrogen species (RNS), UV radiation, and charged particles at 10 atmospheric pressure and room temperature. The investigation of CAP intersects multiple disciplines such 11 as physics, engineering, chemistry, biology, biochemistry, and many others. The goal of this research 12 topic, entitled "Plasma and Related Sciences: Experimental and Theoretical Approaches," is to collect 13 high-quality research related to CAP and plasmas, directly or indirectly, through the associated sciences. In the second article, L. Qiang et al reported that there is currently limited research on how gas ionization 26 affects the pulse formation process in loads driven by pulsed power sources. Therefore, a simulation method 27 using Particle-In-Cell/Moment-Collision Calculation (PIC/MCC) has been proposed to accurately model 28 gas ionization during electron beam generation in Linear Transformer Drivers (LTD). This method integrates 29 the electromagnetic field and charged particles with circuit modules, providing a clearer understanding of 30 the impact of gas ionization on pulse shape. Moreover, excessive gas ionization can lead to impedance 31 mismatches and potential load short circuits.
