On probable fusion mechanism in a Mather-Type plasma focus

Abstract

An experimental study on plasma focus fusion mechanisms is presented in this paper. Simple diagnostic techniques such as current derivative, voltage, and time-integrated neutron detectors are used. This paper allow us to obtain information and fusion mechanisms present in a medium energy plasma focus [ Auto Confined (PACO), 2 kJ, 31 kV, and T = 2,9µs ]. La current sheet (CS) inductance is calculated through the anode voltage and current derivative signals, for some 80 shots performed within the pressure range 0.8-2.1 mbar of deuterium. It is concluded that the CS inductance is consistent with the behavior of a unique plasma sheet moving between two coaxial electrodes. From the information collected, it is concluded that the main fusion mechanism in this device is the beam-target one.
