    Notes: Tearing modes are suspected to be a principal cause of both minor and major disruptions in a tokamak. Suppression of these modes via a neutral beam which supplies momentum, energy and particles of appropriate phase and amplitude is considered. Model theoretical calculations are presented for the stabilization of drift tearing modes and it is found that for ADITYA [S.B. Bhatt et al., Ind. J. Pure Appl. Phys. 27, 710 (1989)] and other present-day tokamak parameters, stabilization is achievable using modest levels of beam power, current and density. © 1997 American Institute of Physics.

    A basic experiment on isotope scaling of transport (2001)
    [S.l.] : American Institute of Physics (AIP)

    Notes: There is considerable divergence between theoretical predictions and tokamak experimental results for the isotopic mass effects on transport. This motivated a basic physics experiment in the Columbia Linear Machine [G. A. Navratil, J. Slough, and A. K. Sen, Phys. Plasmas 24, 184 (1982)]. Experiments were done using two different gases: hydrogen and deuterium. Measurements of particle transport driven by an E×B rotationally driven mode were made via the cross correlation of potential and density fluctuations. Unlike in tokamaks, the plasma parameter profiles and fluctuation spectra were maintained nearly invariant for both gases, thus enabling a meaningful comparison and estimation of scaling. The first series of data reveal smaller transport values for the deuterium plasma and a scaling that ranges as D⊥∝Ai−0.6 to D⊥∝Ai−0.8. © 2001 American Institute of Physics.

    Notes: The effect of viscosity on the stability of a non-neutral plasma is studied. Stability boundaries are obtained for two-dimensional electrostatic perturbations of long wavelengths. It is shown that a configuration with a monotone decreasing number density profile can be unstable when the plasma has viscosity. © 1999 American Institute of Physics.

    Studies of transport scaling and reduction under feedback (1997)

    Notes: A feedback control system using an ion beam as a remote suppressor has been previously shown to be very effective in suppressing plasma instabilities in the Columbia Linear Machine [G. A. Navratil et al., Plasma Phys. 24, 184 (1982)]. The first experimental measurements for the effect of this feedback system on anomalous particle transport, as determined from the cross-correlation of density and potential fluctuations is presented. It is shown that feedback reduces transport due to a rotational E×B mode by up to a factor of 3 in this experiment. Also, it was found that particle transport scales linearly with fluctuation amplitude and feedback control does not alter this scaling. Last, the experimentally observed scaling of particle transport does not agree with any theoretical predictions. © 1997 American Institute of Physics.

    Low frequency modes in strongly coupled dusty plasmas (1998)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Plasmas 5 (1998), S. 3552-3559

    Topics: Physics
    Notes: The influence of strong correlations on low frequency collective modes in a dusty plasma is investigated. The dust dynamics is modeled by the generalized hydrodynamics description. For the well known dust acoustic mode, strong correlations lead to new dispersive corrections, an overall reduction of the frequency and phase velocity and the existence of parameter regions where ∂ω/∂k〈0. A novel result is the possibility of sustaining a low frequency transverse mode—a dust shear mode—in which the correlation energy acts as an effective bulk modulus. The influence of ion streaming and collisional interaction with a background of neutrals on the modes are also studied and it is shown that the longitudinal modes may be driven unstable by ion streaming. © 1998 American Institute of Physics.

    Effect of rigid toroidal rotation on the stability of a tokamak plasma to tearing modes (1997)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Plasmas 4 (1997), S. 239-241

    Topics: Physics
    Notes: The stability of tearing modes in the presence of a rigid toroidal rotation of the plasma is examined. The effect of rotation is modeled by a centrifugal force, which in the cylindrical limit reduces to a uniform force transverse to the plasma column. The influence of this centrifugal force on the outer region matching data Δ, which provides a measure of the energy available for driving the tearing mode, is numerically investigated. It is found that the stability properties of the mode in the presence of the flow are sensitive to the equilibrium density profile. © 1997 American Institute of Physics.

    Hall term enhancement of current drive in a bounded inhomogeneous plasma (1995)

    Notes: The problem of helicity injection and current drive due to ion-cyclotron waves in a bounded inhomogeneous plasma is reexamined. It is shown that Hall term contributions (which had been neglected earlier in the work of Mett and Taylor [Phys. Fluids B 4, 73 (1992)]), even in the limit of small corrections of the order of ω/Ωi (ω and Ωi are the wave and the ion-cyclotron frequencies, respectively), improve substantially the parallel electromotive force (EMF) for the resonance layer. © 1995 American Institute of Physics.
