I wish I could put my tone in a more collaborative way… In fact, I feel pretty much handcuffed given that the much material available to understand how LPPX aims to achieve their objectives is not written down anywhere or is not available outside the lab`s oral tradition (this is quite normal in any research group).

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?
