项目摘要

We have conducted the experiment for clarifying relation between the accumulated charge on the dielectric in barrier discharges and discharge mode. In the experiments using an applied voltage with ringing parts, it was shown clearly that a uniform electric discharge mode is brought about by cancelling (or initializing) surface charge accumulated in the 1st pulse discharge by the 2nd relatively small pulse. Furthermore, we have constructed accumulated charge characterization equipment using the Pockels effect. This succeeded in observing the dynamic behavior of two-dimensional spatial distribution of the accumulated charge in plasma display (PDP) type surface discharge for the first time. In the Xe/Ne gas discharge for PDP, two-dimensional distribution became relatively uniform and was not able to employ efficiently the special feature of two-dimensional measurement of this equipment. However, when helium gas was used, electric charge accumulation began locally on the electrodes, and we were able to observe that charge accumulating domain spreads gradually. This technique was applied to the self-organized filamentary discharge mode which was the original purpose of this research. The amount of accumulated charges was zero in the part where a filament did not exist. In the part where a filament existed, the charge density of 67 nC/cm^2 was found to be accumulated per a filament. Finally, I would like to mention that it becomes possible to measure spatial distribution of the accumulated charge near the filament by using a thinner electro optic crystal as a future prospective. Moreover, by using together the image intensified CCD camera, it is possible to clarify the dynamic behavior of two-dimensional spatial distribution of the charge accumulation for one filament.

为了阐明阻挡放电中介质上的累积电荷与放电方式之间的关系，我们进行了实验。在带环部外加电压的实验中，清楚地表明，通过第二个相对较小的脉冲来抵消（或初始化）第一个脉冲放电中积累的表面电荷，从而产生均匀的放电模式。此外，我们还利用波克尔斯效应构建了累积电荷表征设备。首次成功地观察到等离子体显示（PDP）型表面放电中积累电荷二维空间分布的动态行为。在PDP的Xe/Ne气体排放中，二维分布变得相对均匀，不能有效地利用该设备二维测量的特殊性。然而，当使用氦气时，电荷在电极上开始局部积累，我们可以观察到电荷积累域逐渐扩展。该技术应用于自组织丝状放电模式，这是本研究的最初目的。在不存在灯丝的部分，累积电荷量为零。在有灯丝存在的部分，发现每根灯丝的电荷密度为67 nC/cm^2。最后，我想提到的是，未来有可能使用更薄的电光晶体来测量灯丝附近累积电荷的空间分布。此外，将图像增强CCD相机结合使用，可以明确单根灯丝电荷积累的二维空间分布的动态行为。
