Neutron yield scaling for Plasma-Focus based on Gyrating Particle Model (GPM)

The paper presents preliminary results of computer simulation of the neutron emission from Plasma-Focus based on Gyrating Particle Model (GPM) namely: total neutron yield, intensity of emission along device axis as well as end-on and side-on spectra. Dependence of the total neutron yield on the pinch current (scaling law) is a basic problem analyzed in the paper. It was found that with increase of the total pinch current a rapid increase of neutron yield occurs caused by a trapping of the high energy deuterons in the pinch area. It was also revealed that for sufficiently high current, part of deuterons can drift in the direction of an anode due to strong magnetic field gradient causing a drop of the total neutron yield.
