For example, before downloading Lee`s simulator and asking here a lot of questions, I just thought that just the discharge of a lot of energy with a great voltage would create a lot of current, that is, 2.8MA. But this is not what is required. What is needed is a pressure of 200Torr and such pressure was never achieved by any Dense Focus Fusion device. This is an order of magnitude higher than what is usually assumed as the highest pressure that allows the formation of the pinch.

So, LPPX is different not only because of the axial field, but mainly because of the extremely high pressure of the fuel gas.

So, I`d like to know why is so dangerous to increase the pressure fast?

Well, it seems like if increasing the pressure has never been done before, it might be nice to get some stats on whats happening to the pinch as the pressure is increased . . . so if any corrections or adjustments are needed, they can know what might help in the high pressure environment.

If you have ideas about how the process could go faster, suggest them! I don’t know lots of whats going on but I feel comfortable getting a sense of it as the research proceeds. I don’t think I have enough information to know what goes into the strategic kind of research questions.
