通过两个平行但水平分开的电极产生80 mm宽的氦冷大气压等离子体（CAPP）。CAPP本质上是一个正流光，隔离电极抑制了CAPP的电弧过渡。电极间距和He流量在中等值时都有利于等离子体排出。CAPP的光发射光谱表明，等离子体发生器内部主要是He相关物种，而下游的主要物种是OH自由基、原子O、γ-NO和N2相关物种。此外，CAPP模拟OH线（309 nm）的气体温度近似为室温。
80 mm-wide helium cold atmospheric-pressure plasma (CAPP) was generated via two parallel but horizontally separated electrodes. The CAPP is considered to be essentially a positive streamer, and the separated electrodes suppress arc transition of the CAPP. Both the electrodes' distance and He flow rate at medium values favor plasma expulsion. The optical emission spectra of the CAPP demonstrate that He related species are dominant inside the plasma generator, while the main species downstream are radicals of OH, atomic O, γ-NO and N2 related species. In addition, the gas temperature of the CAPP simulated OH line (309 nm) is approximately room temperature.
