Abstract

We study the structure, motion and collapse of the current sheath (CS) in a small low pressure Plasma Focus (≈ 1 KJ, 0.4 to 3 Torr with D2, 0.03 to 1.4 Torr with A). The observation of a radial component of the magnetic field and the image converter pictures show a complex structure of the CS. However, a snow-plow model is adequate to describe the CS motion as a whole, which in turn, determines the CS thickness regardless of the gas employed. In the focus stage we observe bursts of non thermal microwaves, hard X-rays (0.5 – 1.0 MeV), and neutrons.
