Dena, a new PF device

In this paper we are going to introduce "Dena", a new Filippov type plasma focus facility, with a condenser bank of 0.288 mF, and a maximum supplying energy of 90 kT (at V-max= 25 kV). The facility was installed and started t o work in the first quarter of the year 2000. Major points of the paper are : - Dena's construction, functionality, and diagnostic system. - Preliminar y results: Different modes of neutron, X-ray, and "hot spot" production, as well as the possibility of controlling operational mode, by changing anode configuration and initial discharge condition.
