Production Target Design Report
- Los Alamos National Lab. (LANL), Los Alamos, NM (United States)
The Northstar 99Mo production target, a cylindrical length of 100Mo rod, has evolved considerably since its first conception. The cylinder was very early sliced into disks to increase the heat transfer area, first to 1 mm thick disks then to the current 0.5 mm thick. The coolant was changed early in the target development from water to helium to eliminate corrosion and dissolution. The diameter has increased from initially 6 mm to 12 mm, the current diameter of the test target now at ANL, to nominally 28 mm (26-30.6 mm, depending upon optimal beam spot size and shape). The length has also changed to improve the production to cost ratio, so now the target is nominally 41 mm long (excluding coolant gaps between disks), and irradiated on both ends. This report summarizes the current status of the plant target design.
