Experimental study of Alfv\'en wave reflection from an Alfv\'en-speed gradient relevant to the solar coronal holes

Autor: Bose, Sayak, TenBarge, Jason M., Carter, Troy, Hahn, Michael, Ji, Hantao, Juno, James, Savin, Daniel Wolf, Tripathi, Shreekrishna, Vincena, Stephen

We report the first experimental detection of a reflected Alfv\'en wave from an Alfv\'en-speed gradient under conditions similar to those in coronal holes. The experiments were conducted in the Large Plasma Device at the University of California, Los

Thomson scattering on the Large Plasma Device

Autor: Ghazaryan, Sofiya, Kaloyan, Marietta, Gekelman, Walter, Lucky, Zoltan, Vincena, Stephen, Tripathi, Shreekrishna P., Pribyl, 1 Patrick, Niemann, Christoph

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 a tunable notch filter is used to discriminate the faint scattering s

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 smaller than the Debye length ($\lambda_{De}$) enabled the measurement
