In this paper, we show with the help of two-dimensional numerical simulations that the specific power deposition by a heavy ion beam in matter may significantly decrease due to hydrodynamic expansion of the target during irradiation. It has also been

For heavy-ion inertial-confinement fusion pulsed power techniques are attractive. Pulsed ion beams with a beam duration time of some 10 ns with a repetition rate of some Hz seems to be required. The magnetic flux density in an ion-optical lens must b

This paper describes a laboratory facility capable of simulating time-varying radio multipath channel responses in real time under computer control. Four independent fading channels are available that can be used for single-polarization nondiversity,

The amplitudes of satellite signals sometimes scintillate ± several decibels when heavy cumulus clouds pass through the radio path on hot summer days. These scintillations have been measured on a 19-GHz and 28-GHz earth-space path using 7-m and 0.6-

One year of propagation data were obtained for a 19-GHz earth-satellite path terminating at Crawford Hill, New Jersey. These data were analyzed to determine the depolarizing and attenuating properties of liquid (rain) and solid (ice) hydrometeors alo
