2. If the current carrying rod is sufficiently large (a few millimeters in our installation), it is only partly evaporated by a discharge, and the factors influencing performance can be quantitatively studied. In particular, the amount of material melted and evaporated, and the temperatures reached by the current-carrying sheath, called the M-M (metal-megagauss) interface, can be investigated.

Thermal plasma measurements from the Dynamics Explorer 1 spacecraft using an aperture bias in the outer plasmasphere and over the polar cap show the existence of cold plasma (T ~1 eV) which may otherwise be hidden from the particle detector by positive spacecraft potentials. Operations of the retarding ion mass spectrometer instrument with the external aperture plane biased up to -8 V with resp...

UAV-Borne Profiling Radar for Forest Research

Microwave Radar is an attractive solution for forest mapping and inventories because microwave signals penetrates into the forest canopy and the backscattering signal can provide information regarding the whole forest structure. Satellite-borne and airborne imaging radars have been used in forest resources mapping for many decades. However, their accuracy with respect to the main forest invento...
