approximated well by the exponentially decaying oscillation of an RLC circuit and does not have the slowly modulated (“beating”) envelope typical of a SGTT. The red curve is a fit assuming fixed RLC parameters. The solenoid current is nearly spatially uniform, unlike in some SGTTs, allowing the top voltage to be estimated from the base current as $V_t \approx - L_s \, d I_s/d t$. The inferred peak voltage $|V_t|$ was 201 kV using the variable RLC fit.

In principle, a Marx generator can be adjusted to mimic a SGTT as follows. During operation, a Marx generator charges $N$ stages each with capacitance $C_0$ in parallel and rapidly rewires the stages in series to produce a pulse. Ideally, the maximum output voltage is $N$ times the charging voltage. In contrast, a SGTT charges the capacitance $C_p$ of a primary oscillator circuit and then transfers this energy via resonant coupling to a secondary oscillator circuit with capacitance $C_s$. From energy conservation, the maximum possible output voltage is $\sqrt{C_p/C_s}$ times the charging voltage.[@naidu:1995] Therefore, for the same charging voltage, choosing $C_0 = C_p/N$ leads to the same energy per pulse, and choosing $N = \sqrt{C_p/C_s}$ to roughly the same output voltage.
