一个新的等离子体设施：Vehicle-1已经建成，用于评估创新的面向等离子体的组件概念。该设备可以进行实验，使托盘中的静止液体暴露于垂直流动的等离子体，或者使斜坡上的流动液体受到水平方向等离子体的轰击。Vehicle-1可以产生密度约为1010 cm − 3、电子温度约为4 eV的稳态氢等离子体。已经在媒介物-1中观察到氢再循环行为，并且速率常数的Arrhenius图在约300°C处显示出断裂。断裂点以下和断裂点以上的活化能分别为-0.0096eV和0.17eV。为了理解氢循环的动力学，已经测量了颗粒粘附系数。结果表明，在温度低于突破的粘附过程似乎是限速，而以上的突破表面重组是重要的。已经发现等离子体物种的粘附系数比氢分子的粘附系数大几个数量级。
A new plasma facility: Vehicle-1 has been built for the evaluation of innovative plasma-facing component concepts. This facility can conduct experiments in such a way that standing liquids in a tray are exposed to vertically flowing plasmas, or that flowing liquids on a slope are bombarded with horizontally directed plasmas. Vehicle-1 can generate steady state hydrogen plasmas with densities of the order of 1010cm−3and electron temperatures around 4eV. Hydrogen recycling behavior has been observed in Vehicle-1, and the Arrhenius plot of rate constants exhibits a break at around 300°C. The activation energies are −0.0096eV and 0.17eV, respectively, below and above the break. To understand the kinetics of hydrogen recycling, particles sticking coefficients have been measured. Results indicate that at temperatures below the break the sticking process appears to be rate-limiting, whereas above the break surface recombination is important. The sticking coefficients for plasma species have been found to be orders of magnitude larger than those for hydrogen molecules.
