However, accurately measuring the energy delivered to the plasma in nanosecond pulse systems is difficult due to the influence of the inherent parasitic components of the electrical characteristics of the system. This study develops and validates methods for measuring the delivered energy in NPDBD, thereby ensuring accurate energy efficiency measurements. We proposed precise discharge current measurement methods by comparing the experimental and simulation results. We conducted toluene decomposition experiments under varying applied voltage and pulsewidth conditions, which revealed an energy efficiency range of 35-45 g/kWh. The validated energy measurement methods present a foundation for the removal of VOCs in NPDBD systems, presenting more efficient electrical conditions for industrial applications.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"54 4","pages":"1366-1376"},"PeriodicalIF":1.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147685523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This lies outside conventional textbook physics predictions, yet its reality has been indicated previously and if eventually confirmed will have a significant effect on physics theory and many technological applications, especially those involving high-current density (<inline-formula> <tex-math>$gt$ </tex-math></inline-formula>10<sup>9</sup> A/m<sup>2</sup>) including EM mass drivers such as railguns with liquid metal sliding contacts, flux compression generators and also high-energy plasmas including fusion and other energy technologies. The experiment described here is based on the measurement of force on a supported copper armature submerged in a trough containing liquid metal through which constant dc current is passing. The coaxial symmetry of the experiment, coaxial recoil experiment (CRE), was able to limit all net force on the centered armature to the direction of interest, parallel to the current within it. All the experimental data related the measured forces on the armature to the total current flowing through the circuit. Variations were made to the length and location of the armature along the central axis as well as modifications to the liquid metal configuration. Raw and processed results are presented, and an experimental technique is described that revealed strong evidence for the existence of, and discrimination between, axial mechanical contact forces between solid and liquid metal as well as longitudinal EM force. The original EM force law, proposed in 1822 by Ampère, includes a longitudinal component and has been found to be qualitatively consistent with all experiments to date, including these reported findings, and is considered a candidate explanatory theory.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"54 4","pages":"1867-1873"},"PeriodicalIF":1.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147685361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article, the proposed TPMLL consists of the following parts: the outer stator, outer air gap, mover made of permanent magnets (PMs), inner air gap, and the inner stator. A magnetic equivalent circuit (MEC) method is established to analyze the electromagnetic characteristics and provide the basis for the structural design. To solve the MEC model, the Newton–Raphson method is adopted. By comparing the results of the finite element method (FEM) with the MEC model, it is found that the accuracy of MEC method has good accuracy in estimating the flux linkage of the proposed motor, which is very suitable to be used in the initial stage of the structural design.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"54 4","pages":"1858-1866"},"PeriodicalIF":1.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147685333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the existing pulsed power system cannot meet the demand of the HF-PMF (>1 kHz). In this article, a high repetition frequency pulsed power system (HRF-PPS) is proposed to generate an HF-PMF, which has the advantages of high stability, steep falling, and rising edges. HRF-PPS consists of three parts: a high peak-to-average power ratio pulsed power generator (PAPR-PPG) to produce a high-frequency square pulsed current, a capacitor charging power supply (CCPS) to supplement capacitor energy, and a magnet to generate a magnetic field (MF). The steep rising and falling edges are achieved by releasing and storing the capacitor energy to and from the magnet. The magnet is designed by simplified quadratic programming (QP) and particle swarm optimization (SQP-PSO) to minimize the magnet heat generation. Experimental results demonstrate that the HRF-PPS generates an HF-PMF of 0.1 T at 2 kHz, which aligns with simulation results and verifies the feasibility of the proposed idea.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"54 4","pages":"1340-1347"},"PeriodicalIF":1.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147685358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
