兆瓦级强流离子源长脉冲运行分析及实验研究

强流离子源是高功率中性束注入系统的关键部件,其长脉冲稳定运行是目前的挑战之一。针对热阴极离子源的工作原理,分析了强流离子源的运行特性。针对强流离子源的打火问题,开展了基于打火再起的自调整技术研究,即在离子源发生异常(如打火)时及时终止离子源的束引出从而保护离子源的安全,在随后百毫秒下重新进行离子束的引出,从而获得强流离子源的长脉冲运行。在兆瓦级强流离子源上开展了基于打火再起技术的运行测试,获得了兆瓦级离子束27 s长脉冲稳定运行,为高功率的离子源长脉冲运行提供支持。

Face Detection Technology Based on Robot Vision

One being developed automatic sweep robot, need to estimate if anyone is on a certain range of road ahead then automatically adjust running speed, in order to ensure work efficiency and operation safety. This paper proposed a method using face detection to predict the data of image sensor. The experimental results show that, the proposed algorithm is practical and reliable, and good outcome have been achieved in the application of instruction robot.
