Query: Simulating the Diffference between a DES and a Simple Railgun using
  SPICE   A DES railgun increases the launch efficiency when compared to a simple
railgun setup. In a 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.
