Strong Nonlinear Alfvén Wave Interactions in a Laboratory Plasma
C. H. K. Chen, S. Dorfman, S. Boldyrev +6
Alfvén waves and their nonlinear interactions are ubiquitous in space and astrophysical plasmas, and are thought to play important roles in the dynamics of these systems, yet their…
Measurement of energy reduction by inertial Alfvén waves propagating through parallel gradients in the Alfvén speed
Garima Joshi, Sayak Bose, Troy Carter +4
We have studied the propagation of inertial Alfvén waves through parallel gradients in the Alfvén speed using the Large Plasma Device at the University of California, Los Angeles.…
Experimental study of Alfvén wave reflection from an Alfvén-speed gradient relevant to the solar coronal holes
Sayak Bose, Jason M. TenBarge, Troy Carter +6
We report the first experimental detection of a reflected Alfvén wave from an Alfvén-speed gradient under conditions similar to those in coronal holes. The experiments were conduct…
Laboratory study of magnetic reconnection in lunar-relevant mini-magnetospheres
Lucas Rovige, Filipe D. Cruz, Robert S. Dorst +7
Mini-magnetospheres are small ion-scale structures that are well-suited to studying kinetic-scale physics of collisionless space plasmas. Such ion-scale magnetospheres can be found…
Thomson scattering on the Large Plasma Device
Sofiya Ghazaryan, Marietta Kaloyan, Walter Gekelman +5
We have developed a non-collective Thomson scattering diagnostic for measurements of electron density and temperature on the Large Plasma Device. A triple grating spectrometer with…
Measured reduction in Alfvén wave energy propagating through longitudinal gradients scaled to match solar coronal holes
Sayak Bose, Troy Carter, Michael Hahn +3
We have explored the effectiveness of a longitudinal gradient in Alfvén speed in reducing the energy of propagating Alfvén waves under conditions scaled to match solar coronal hole…
Observations of a Field-Aligned Ion/Ion-Beam Instability in a Magnetized Laboratory Plasma
P. V. Heuer, M. S. Weidl, R. S. Dorst +8
Collisionless coupling between super Alfvénic ions and an ambient plasma parallel to a background magnetic field is mediated by a set of electromagnetic ion/ion-beam instabilities…
Modification of turbulent transport with continuous variation of flow shear in the Large Plasma Device
D. A. Schaffner, T. A. Carter, G. D. Rossi +4
Continuous control over azimuthal flow and shear in the edge of the Large Plasma Device (LAPD) has been achieved using a biasable limiter which has allowed a careful study of the e…
Laboratory measurements of electrostatic solitary structures generated by electron beam injection
Bertrand Lefebvre, Li-Jen Chen, Walter Gekelman +6
Electrostatic solitary structures are generated by injection of a suprathermal electron beam parallel to the magnetic field in a laboratory plasma. Electric microprobes with tips s…
Control of gradient-driven instabilities using shear Alfvén beat waves
D. W. Auerbach, T. A. Carter, S. Vincena +1
A new technique for manipulation and control of gradient-driven instabilities through nonlinear interaction with Alfvén waves in a laboratory plasma is presented. A narrow field-al…
