Аннотация

In the SINUS family of pulsed, high current electron beam accelerators [1], the energy stored within a coaxial forming line (usually oil-insulated) is delivered to a load by means of a high voltage pressurized spark gap switch. For better matching to the load, a transmission line having a nonuniform wave impedance may be included between the switch and the load. Numerical simulation of the system described above has been performed with the use of 2.5D version of 2.5 & 3D, fully electromagnetic PIC-code KARAT [2]. Geometrical parameters of several SINUS accelerators were used. Actual spatial configurations of the gas switch were considered, but the time dependent spark resistance between the electrodes was included as a variable. The obtained results are compared with actual pulse shapes from experiments. Conclusions are drawn about how the spark resistance as the function of time effects the pulse observed.
