Abstract1 pyUzHF0  
Dense Plasma Focus (DPF) discharge is a very promising %-?k [DL6  
mechanism to achieve high neutron production yield "2 \},o9  
(about 1011–1012 per pulse) from the D-T reactions. Focus #~}4< 18  
is conjectured to be a finite 2D Z-pinch formation near the d+qeZGg^A  
end of the coaxial plasma accelerator, typically having the ^O0trM>h-  
density above the level of 1019/cm3 and temperature of a 8I8{xt4   
few keV during 100 to 150 ns. Interest to DPF appeared KWS\iu  
since the pioneer experiments of Filippov and the first Six2{b)p  
theoretical reviews of Dyachenko and Imshennik and PGd?c#v#  
Mather. During the last decades theoretical investigation U8S<wf&  
of DPF lagged behind the experiments, giving scant explanation ?_-5W9  
of the experimental results. At the same time q}PUwN6  
modeling and diagnostic capabilities have been dramatically cqYMzS t  
improved. This presentation shows that the computer vRkVPkZ6|  
simulation by the code MHRDR (Magneto Hydro _<Ip0?N  
Radiative Dynamic Research) can help meet the goals and
n +v(t  
challenges of the LANL – Bechtel Nevada Dense Plasma h3e %(a  
Focus Accelerator project. Theoretical estimations, made ^*G UcQ$  
in this report, represent the bounds between the parameters B#]:1:Qn  
of source generator, geometry of the electrodes and  o,rK8x  
feeding circuit and the initial density of the background b{BiC&3  
gas in the form of the simple scaling laws. \E {'|
