Abstract F+*fim'N
K  
The Decade Half x-ray radiation simulator will combine 4!OGNr$V@  
the outputs of eight synchronized modules to produce a $m~&|s  
current of up to 13 MA delivered to a short circuit load in (,t[`z  
~300 ns. Decade is located within the Decade Radiation Xn?.Od(  
Test Facility (DRTF) at the Arnold Engineering .I EHjy\+  
Development Center, Tullahoma, TN. Decade's output r7].48D  
will be used for nuclear weapons effects testing; the r~JGs
?GH  
DRTF will reach initial operational capability (IOC) in !Yr9N4

DoD's X-ray Radiation Simulator R&D Program is d>mT+{3  
focused on maximizing 3.1 keV x-ray fluence from >Ut: -}CS  
Decade's argon z-pinch. Electric current risetime will be A`JE(cIz3  
approximately a factor of 3 longer than typically used to q9p31b3  
drive plasma radiation source (PRS) loads. Scaling to fVgN8b|&'  
longer current risetime is advantageous in terms of 5M~+F"Hl  
reduced driver cost and complexity. The use of longer }:YL'$:5!  
pulse drivers, however, requires an increase in the initial B6;>V`!  
diameter of the z-pinch gas puff. The unique challenge is q]C_idK=  
to extend the success with 100 ns current risetime nSh~mP  
simulators into the realm of the 300 ns current risetime of l`l6Y>c*]  
Decade. As the diameter is increased, increased S
rB>_0**  
asymmetry and instability can limit the ability of the load ,Y6]x^
W  
to produce K-shell radiation efficiently. These effects [0105l5  
were largely un-quantified until technical investigations V=5S=7 Z:  
were conducted under the auspices of the Simulator R&D ~OsLbz:  
Program. This paper discusses progress, activities and iLJ@oM;2  
issues in developing the large diameter z-pinch for LC##em=Y
