中文摘要
X射线发射是为了使绝缘剂的电化已经被实验证实。通过压力、真空、绝缘剂材料、大气气体、应用电压、电流(DC或AC)的变化,对X射线发射的电气充电效应进行了广泛的研究。发现X射线只被强有力地发射,当真空在10-D1 Torr上的范围非常狭窄。X射线发射是非常不稳定的,即使我们可以控制的实验条件也改变了。这种X射线发射的物理机制已经明确;它是为了电子轰击。使用这种现象,我们已经构造了一个使用1.5 V电池和高电压逆变器的X射线产生装置。这个设备很小,而且它已经被观察到了X射线产生的重要强度。这个设备生产的X射线再次非常不稳定,我们试图通过稳定的X射线产生的条件来确定它。However,在我们工作的目前阶段,我们还没有找到这样的实验条件我们相信,在未来,对收费效果的研究将需要。
英文摘要
X-Ray Emission due to electrification of insulator has been confirmed experimentally. The experimental conditions of X-ray emission due to the electric charge-up effect have been extensively studied with the change of pressure, vacuum, insulator material, atmospheric gas, applied voltage, electric current (DC or AC), and so on. It is found that the X-rays are only strongly emitted when the vacuum is a very narrow range on the 10ィイD1-2ィエD1 Torr. The X-ray emission is very unstable even though we changed the experimental conditions as far as we could control. The physical mechanism of this X-ray emission has been clarified; it is due to electron bombardment.Using this phenomena, we have constructed an X-ray generating device using a 1.5 V battery and high voltage inverter. This device is quite small, and it has been observed that significant strength of X-rays were generated. The X-rays produced by this device was again very unstable, and we tried to find a condition by which the stable X-rays were generated. However, at the present stage of our work, we have not yet found such an experimental condition. We believe that the study of charge-up effect should be needed in the future.
