为了有效利用外磁场等离子射流的吸引力特性，对等离子体射流的功能增强进行了基础研究。使用一对超导线圈将磁场施加到真空室中的射流上。两个线圈之间的射流行为由数码相机通过窗口拍摄进行观察。图像分析表明，射流受到强磁场的径向收缩。然而，射流中心周围的高亮度区域随着场强的增加而增加。还在从射流中心到外边缘的横向位置进行发射测量。排放测量的结果也支持图像分析所示的射流收缩。从这些结果可以看出，通过使用强磁场可以显着地控制等离子体射流。
A fundamental study of functional enhancement of plasma jet with external magnetic field was carried out to utilize the attractive properties effectively. The magnetic field was applied to the jet in a vacuum chamber by using a pair of superconducting coils. The behavior of the jet between two coils was taken by a digital camera through the window for observation. The image analysis shows that the jet is constricted radially by the strong magnetic field. However, high brightness region around the center of the jet increases with the field strength. Measurement on the emission was also performed at lateral positions from the center to the outer edge of the jet. The results of emission measurement also supported the constriction of the jet illustrated by the image analysis. It is clarified from these results that the plasma jet can be controlled significantly by using the strong magnetic field.
