Abstract1 ]DK.4\^  
Dense Plasma Focus (DPF) discharge is a very promising o>y@1%aU  
mechanism to achieve high neutron production yield "q7pkxEuJ  
(about 1011–1012 per pulse) from the D-T reactions. Focus L[. )!c8k  
is conjectured to be a finite 2D Z-pinch formation near the ?Vc/mO2X  
end of the coaxial plasma accelerator, typically having the !U~S7h}  
density above the level of 1019/cm3 and temperature of a qFwAzW

few keV during 100 to 150 ns. Interest to DPF appeared `e}6/~R`  
since the pioneer experiments of Filippov and the first K{`3,U2Wx  
theoretical reviews of Dyachenko and Imshennik and Jzj>=jWX@  
Mather. During the last decades theoretical investigation nq*D91Q  
of DPF lagged behind the experiments, giving scant explanation

of the experimental results. At the same time B18?)LA  
modeling and diagnostic capabilities have been dramatically <(x!P=NM-  
improved. This presentation shows that the computer 6G;t:[H G  
simulation by the code MHRDR (Magneto Hydro "[2D&\$  
Radiative Dynamic Research) can help meet the goals and 4=ZN4=(_[  
challenges of the LANL – Bechtel Nevada Dense Plasma {TC_ 4Y|8  
Focus Accelerator project. Theoretical estimations, made c#T0n !}  
in this report, represent the bounds between the parameters VcORRUp

feeding circuit and the initial density of the background ?dQ#%06mn
