On the correction of the transient ground resistance at early times in lightning surge propagation studies

The impact of the ground losses on transient surges that propagate along transmission lines is taken into consideration in the telegrapher’s equations through the so-called transient ground resistance function ξ’g(t), for which numerous ex-pressions exist. ...

Study of Ionized Particles in a Gyrotron Using a Full Gyrotron Simulation Model

Jean-Philippe Hogge, Jérémy Genoud

The ionization of the residual gas in gyrotrons causes the generation of positively charged ions and negatively charged electrons. Using the electron optics code Ariadne, it was possible to simulate the behavior of these electrons in the overall gyrotron g ...
