Abstract

The generation and maintenance of large volume, low-temperature, high-pressure plasmas in air remain a formidable challenge. Toward this goal, several methods, which include the use of dielectric barrier discharges (DBDs) and the resistive barrier discharge (RBD) have been investigated by our group with some limited success. Here, we report on a promising method that we have been developing in our laboratory: a diffuse, nonthermal discharge, in atmospheric pressure air, generated between a planar disk-shaped metal electrode and a second electrode made of a static volume of water contained in a shallow glass dish. Presently, we have used only tap water as one of the electrodes. However, other liquids with low conductivity could also be used. In this paper, the current-voltage characteristics and gas temperature measurements of the discharge are presented. Potential applications of this atmospheric pressure discharge include decontamination, radiation sources, etc.

利用水电极在空气中产生大气压非平衡扩散放电

在空气中产生和维持大体积、低温、高压等离子体仍然是一个艰巨的挑战。为了实现这一目标，我们研究了几种方法，包括使用介质阻挡放电(DBDs)和电阻阻挡放电(RBD)，但取得了一些有限的成功。在这里，我们报告了我们在实验室开发的一种很有前途的方法:在常压空气中，在平面圆盘形金属电极和由浅玻璃盘子中含有静态体积的水制成的第二电极之间产生弥漫性非热放电。目前，我们只使用自来水作为电极之一。然而，其他低导电性的液体也可以使用。本文介绍了放电的电流-电压特性和气体温度测量。这种常压排放的潜在应用包括去污、放射源等。
