Abstract
A DES railgun increases the launch efficency when compared to a simple
railgun setup. In a {\sc Ngspice}-Simulation a DES and a simple railgun setup
connected to an existing 10-MJ capacitor based
power supply are compared. Important parameters like velocity, power
and efficiency are used to quantify the performance gain, when using
the mechanically more complex DES setup. The results of this study
were used to select the simple railgun setup as the design for a new barrel
to the 10-MJ power supply.
