Surface Instability of a Vertically Oscillating Granular Layer

Chinese Physics Letters, 2001
In the study of the surface instability of a vertically oscillating granular layer, we obtained experimentally the phase diagram for the surface states of the layer in the driving frequency-acceleration plane, and measured the dispersion relation for the surface waves in a granular layer in comparison to that in viscous fluids.

Control of the EHR plasma vertical instabilities

[Proceedings] The 14th IEEE/NPSS Symposium Fusion Engineering, 2002
The author presents the conceptual design of the plasma vertical instability control system in the EHR (Experimental Hybrid Reactor). It has been demonstrated that the plasma-vacuum vessel-shell-active coil control system can stabilize the EHR plasma displacement in the vertical direction successfully.
