项目摘要
Dust particles of micron size are negatively charged in a plasma and are confined in a plasma to remain charge neutral as a system. Dust particles can be suspended in a plasma by the balance of sheath electric force and gravity, and are visible through the scattering of laser light applied from the outside of the chamber. Novel structures of dust particles are observed, including the low-dimensional structures in a cryogenic plasma, two-dimensional structures formed in a horizontal plane of the sheath, and collective oscillations with extremely low frequency. The bow shock pattern is realized by dust particles, which helps to understand the basic structures of planetary bow shock. The vortex and mass ejection are observed in the application of strong magnetic field. On the other hand, the double helical structure found in a simulation gives a platform to understand the helix commonly observed in DNA. In conclusion, our research on complex plasma opened a new field in a plasma physics.
微米尺寸的灰尘颗粒在等离子体中带负电,并被限制在等离子体中以保持系统电中性。灰尘颗粒可以通过鞘层电力和重力的平衡悬浮在等离子体中,并且通过从腔室外部施加的激光的散射可见。观察到尘埃颗粒的新颖结构,包括低温等离子体中的低维结构、鞘层水平面中形成的二维结构以及极低频的集体振荡。弓形激波模式是由尘埃粒子实现的,这有助于理解行星弓形激波的基本结构。在强磁场的作用下观察到涡旋和质量喷射。另一方面,模拟中发现的双螺旋结构为理解 DNA 中常见的螺旋提供了一个平台。总之,我们对复杂等离子体的研究开辟了等离子体物理学的新领域。
