Dependence of fast-ion transport on the nature of the turbulence in the Large Plasma Device
Strong turbulent waves (dn=n 0.5, f 5-40 kHz) are observed in the upgraded Large Plasma Device [W. Gekelman, H. Pfister, Z. Lucky, J. Bamber, D. Leneman, and J. Maggs, Rev. Sci. Instrum. 62, 2875 (1991)] on density gradients produced by an annular obstacle. Energetic lithium ions (Efast= Ti 300, qfast=qs 10) orbit through the turbulent region. Scans with a collimated analyzer and with probes gi...
متن کاملTransport of thermal plasma above the auroral ionosphere in the presence of electrostatic ion-cyclotron turbulence
The electron component of intensive electric currents ̄owing along the geomagnetic ®eld lines excites turbulence in the thermal magnetospheric plasma. The protons are then scattered by the excited electromagnetic waves, and as a result the plasma is stable. As the electron and ion temperatures of the background plasma are approximately equal each other, here electrostatic ion-cyclotron (EIC) tu...

متن کاملModeling of plasma turbulence and transport in the Large Plasma Device
Numerical simulation of plasma turbulence in the Large Plasma Device LAPD W. Gekelman, H. Pfister, Z. Lucky et al., Rev. Sci. Instrum. 62, 2875 1991 is presented. The model, implemented in the BOUndary Turbulence code M. Umansky, X. Xu, B. Dudson et al., Contrib. Plasma Phys. 180, 887 2009 , includes three-dimensional 3D collisional fluid equations for plasma density, electron parallel momentum...
متن کاملSuppression of Turbulence in the Large Plasma Device via Rotation
Suppression of turbulence has been observed in the Large Plasma Device in the presence of flow shear. Using an iris-like setup of biasable metal plates called limiters, azimuthal flow near the edge of the device was achieved. The limiters extend from the inner surface of the device inward, 28.5cm from the central axis, and are set from 0 V to 200 V above the anode. Multiple probing methods incl...
