We report on the generation of high transient heat and particle fluxes in a linear plasma device by pulsed operation of the plasma source. A capacitor bank is discharged into the source to transiently increase the discharge current up to 1.7 kA, allowing peak densities and temperature of 70×1020 m-3 and 6 eV corresponding to a surface power density of about 400 MW m-2.

    Particle balance measurements have been performed in low-density [N[sub e](r = 0)< 1011 cm[sup -3]], low temperature [ Te(r = 0)< 5 eV] hydrogen plasma discharges in a linear gas-target divertor simulator device. Axial density drops of up to a factor 50 were observed at high gas-target pressures...

    The effect of a zeroth-order density gradient on the development of cavitons has been investigated experimentally and numerically. The cavitons were produced via excitation of electron plasma waves (EPW) with a modest (E2/4Ï€nTe<1) resonant radio-frequency pump. The location of the resonance,...

    Two new high resolution detectors have been installed on the Alcator C-Mod tokamak to measure the neutral density and ionization rate at the edge of the main chamber plasma. Using a silicon detector sensitive to UV light, and a very narrow filter with transmission peaking at 1216 Ã…, the...

    The broadband reflectometry system on ASDEX Upgrade is now routinely providing electron density profiles with a minimum temporal spacing of 30 μs. The plasma is probed from zero density to n[sub e]=6.64×10[sup 19] m[sup -3] at the low field side with combined O and X modes, and from n[sub...

    Tapered plasma channels are considered for controlling dephasing of a beam with respect to a plasma wave driven by a weakly relativistic, short-pulse laser. Tapering allows for enhanced energy gain in a single laser-plasma accelerator stage. Expressions are derived for the taper, or longitudinal...
