N2 - Dense plasma focus devices have been and will continue to be extensively studied, in their first three stages, namely, the breakdown, rundown, and focusing of the plasma column. However, one of its features has been neglected; namely, the expansion of its discharge along the vacuum chamber, after the compression of the plasma column, which is akin to those in plasma guns. This work is motivated by the possibility of using this stage as a source of energetic plasma, which might simulate the effect of high density plasmas colliding on wall facing materials. For this purpose, it is necessary to be able to determine the dynamics of the discharge, for which measurements of density, temperature and speed are needed. We show preliminary results obtained using a triple Langmuir probe (TLP). The present work is done along the axis of the FN-II dense plasma focus, which is a 4.8 kJ device.
