制作了具有真实交流型结构和尺寸的三维（3-D）观测单元，并首次利用光学发射和激光吸收光谱技术对Xe原子的激发时空行为进行了测量。作为一个典型的特征，可以看到放电从阳极的时间边缘开始，向阴极延伸，在阳极一侧出现受激原子的条纹图案，而在阴极一侧分布一个更宽的峰，向远端移动。此外，在受激原子的分布中可以清楚地看到对外加电压的依赖，这表明了电荷积累对壁面的影响。利用发射和吸收测量中侧面和正面的二维投影图像，初步尝试用迭代法求出三维空间中受激Xe原子的峰值。
A three-dimensional (3-D) observation cell with realistic AC-type structure and size was fabricated and measurements were done, for the first time, on the spatiotemporal behaviors of excited Xe atoms by using optical emission and laser absorption spectroscopic techniques. As a typical characteristic feature, it is seen that the discharge starts from the temporal anode edge, stretching toward the cathode, and a striated pattern of excited atoms appears on the anode side while a single broader peak distributes on the cathode side, traveling to its far end. In addition, the dependence on the applied voltage was clearly seen in the distribution of excited atoms, which shows the influence of the charge accumulation on the walls. With the two-dimensional projection images obtained from side and front views in both the emission and absorption measurements, an iterative method was tried preliminarily to derive the peak values of excited Xe atoms in the 3-D space.
