asymmetric_implosionI think I better understand your goal, but if you are looking at truly external power should you be looking at the power supply charging the capacitors. The rest of the circuit is difficult to treat as two terminals. I’ve tried similar approaches to the one you describe but there are some problems that are difficult to model. I have attached a poster I gave at ICOPS back in 2012 on the dynamics problem. The snow plow model was used to calculate the important dynamic circuit parameters using both the current and the voltage at the load. This was done for a 230kA plasma focus for a couple hundred shots in D2
The energy in the bank is a surprise to me. When I’ve measured the capacitor voltage on my old machines, I never saw more than 10% of the initial charge voltage on the bank at peak current for optimal conditions. I could always force the device to implode early or late which impacted the energy stored in the bank but that never gave the desired radiation yields.
