摘要:

Parylene (C8H8) disks have been irradiated with Nd:YAG‐glass laser pulses focused to flux levels in the 1015to 1017W/cm2range. The flux level was varied by changing the pulse length (50–150 psec), the laser energy (5–15 J), and the axial position of the target with respect to thef/1.1 focusing lens. An extensive array of diagnostics was used to measure the temporal and energy distribution of the focused laser light at the target, the temporal and angular distribution of the scattered laser light, the x‐ray spatial and spectral emission characteristics, and the emitted ion and electron energy distributions. The experimental results, together with two‐dimensional numerical simulations imply absorption via collective processes, laser generation of suprathermal electrons, and transport inhibition consistent with the presence of mega‐Gauss level thermoelectric magnetic fields.

摘要:

A vertical sheet of particles which are initially arranged in a diagonal lattice will tend to form clumps as it falls. The prediction of this clumping requires consideration of all neighbors, thus limiting the usefulness of the simpler nearest neighbor approximation.

摘要:

Toroidal equilibrium calculation was carried to the second order in the inverse aspect ratio. The plasma‐vacuum boundary was assumed circular and the shape of conducting shell was determined. The major axis of the conducting shell lies in thez=0 plane.
