Abstract 2f4c;YS  
The Decade Half x-ray radiation simulator will combine nHrCSfK  
the outputs of eight synchronized modules to produce a jtY~-@*  
current of up to 13 MA delivered to a short circuit load in PlUjjJU  
~300 ns. Decade is located within the Decade Radiation y*(j{0yd  
Test Facility (DRTF) at the Arnold Engineering  O+j:L  
Development Center, Tullahoma, TN. Decade's output *)I1gR~  
will be used for nuclear weapons effects testing; the ~Xw?
>&  
DRTF will reach initial operational capability (IOC) in _AbEQ\P{  
2007. J@iN':l-  
DoD's X-ray Radiation Simulator R&D Program is #Q7$I.O]  
focused on maximizing 3.1 keV x-ray fluence from -P
&e4sV{  
Decade's argon z-pinch. Electric current risetime will be = h( n+y<  
approximately a factor of 3 longer than typically used to W9'jzP  
drive plasma radiation source (PRS) loads. Scaling to -`EoTXT*U  
longer current risetime is advantageous in terms of ^W'[l al.  
reduced driver cost and complexity. The use of longer j}l8k@f  
pulse drivers, however, requires an increase in the initial SqB|(~S  
diameter of the z-pinch gas puff. The unique challenge is @~3c;9LkY  
to extend the success with 100 ns current risetime %Ege^4PE  
simulators into the realm of the 300 ns current risetime of v{Vesf  
Decade. As the diameter is increased, increased QovC*1'  
asymmetry and instability can limit the ability of the load 3kY4V*9@-  
to produce K-shell radiation efficiently. These effects .YF-t`{  
were largely un-quantified until technical investigations $:wM'&M  
were conducted under the auspices of the Simulator R&D q04Dj-2<  
Program. This paper discusses progress, activities and zmRK%a(  
issues in developing the large diameter z-pinch for 3PffQ,c[~
