This project will be focussed on the development of an advanced ion-extraction device. The main aim will be to study the fundamentals of low-temperature plasmas so that the properties of the plasma can be taken advantage of to produce the charge separation that is the core aim of the project. It will be using current experimental techniques to generate non-equilibrium, low-temperature plasmas to investigate new innovative methods of achieving ion-extraction. My current work involves generating a non-equilibrium, low-temperature plasma to convert carbon dioxide to carbon monoxide. The aim is to build an experiment with a reduced electrode-electrode distance so that we move down the Paschen curve to increase the energy and conversion efficiency. Also by using an increased frequency, i.e. one of the higher harmonics of 13.56MHz, we can utilise the energy of the electrons to increase the amount of alpha mode ionisation events, thus increasing the stability and conversion of carbon dioxide.

该项目将集中于开发一种先进的离子提取装置。主要目的是研究低温等离子体的基本原理，以便利用等离子体的特性来产生电荷分离，这是该项目的核心目标。它将利用目前的实验技术来产生非平衡、低温等离子体，以研究实现离子提取的新的创新方法。我目前的工作涉及产生一种非平衡的低温等离子体，将二氧化碳转化为一氧化碳。我们的目标是建立一个减少电极间距离的实验，这样我们就可以沿着帕邢曲线向下移动，以增加能量和转换效率。此外，通过使用增加的频率，即13.56MHz的高次谐波之一，我们可以利用电子的能量来增加α模式电离事件的量，从而增加二氧化碳的稳定性和转化率。
