Vertical Positional Instability in JT-60SU

Fusion Engineering and Design, 1998
Abstract JT-60SU has been designed as an experimental device to establish an integrated scientific basis of steady-state tokamak operation. The high elongation of plasma cross section is employed to keep the safety factor at the plasma surface high for high current operation.

Passive Control of the Vertical Instability in Intor

Fusion Technology, 1985
In the international tokamak reactor (INTOR), the problem of the passive control of the vertical instability is to be solved by means of suitably shaped saddle coils to be embedded in the blanket structure. The efficiency of such a system depends on the characteristics of the passive conductors and on the plasma equilibrium as well as on the type of ...

The Vertical Instability in a Positron Bunched Beam

Physical Review Letters, 1995
The results of experiments on the vertical instability observed in both positron and electron multibunch accumulations at the Photon Factory storage ring are presented. The betatron sidebands, which indicate a vertical instability, appear at different frequency regions depending on the polarities of the beam.

Rayleigh–Bénard instability in a vertical cylinder with a vertical magnetic field

Journal of Fluid Mechanics, 2002
This paper presents two linear stability analyses for an electrically conducting liquid contained in a vertical cylinder with a thermally insulated vertical wall and with isothermal top and bottom walls. There is a steady uniform vertical magnetic field.

Vertical Instability in KEK Booster

IEEE Transactions on Nuclear Science, 1983
In the KEK Booster Synchrotron, from one msec after injection to extraction timing, beam intensity is stable, though it is reduced to about one half during one msec after injection. An instability of the vertical direction is one of the candidates of the beam loss.

Meandering Instability of a Vertical Plume

Journal of Engineering Mechanics, 2009
The meandering instability of a two-dimensional vertical plume is considered in this paper. The base flow profile is derived using boundary layer approximation and similarity hypothesis, in the spirit of Blasius boundary layer solution. Using linear stability analysis, we derive a modified version of the Orr-Sommerfeld equation governing the ...

Instabilities in vertically vibrated fluid-grain systems

The European Physical Journal E, 2007
When a bed of fluid-immersed fine grains is exposed to vertical vibration a wealth of phenomena may be observed. At low frequencies a horizontal bed geometry is generally unstable and the bed breaks spatial symmetry, acquiring a tilt. At the same time it undergoes asymmetric granular convection.
