variable RLC fit is 201 kV (using the fixed RLC fit, 228 kV). The charging voltage can be approximated as this divided by 18, giving 11.2 kV, which is close to the maximum value of 12.4 kV expected from the power supply in Fig. 2(e) with the Variac set to 140 $V_\text{rms}$ assuming a 120 Hz repetition rate. For an erected bank capacitance of 37 pF, this corresponds to a charging energy of at least 0.75 J in the Marx bank. Including estimates for the solenoid and terminal contributions given above, the total effective output capacitance is roughly 50.5 pF, which corresponds to a charging energy of 1.0 J.

Discharge loading of Tesla transformers
---------------------------------------

Unfortunately, the effects of spark discharge loading on Tesla transformers have not been extensively studied.[@craven:1997] Neither has the related subject of optimizing a Tesla transformer to generate the longest discharge over single or multiple pulses, unlike optimizing to produce the maximum voltage in a single pulse without discharge.[@denicolai:2002] These two goals are not identical because nonuniform electric fields normally create the discharge and the longest discharges may form over multiple pulses.

However, the common approach to maximize the discharge length for a Tesla transformer provides
