Development of Tools for Assembly of High-Energy-Density Physics Targets

The University of Michigan fabricates targets for high-energy-density physics experiments. Experimenters use these targets at a variety of facilities such as the Omega Laser Facility, the Jupiter Laser Facility, the Z machine, and others. Many experiments involve targets with small (< 1 mm) precisely positioned components, multi-step assemblies, and compound angles. These complex targets are hand assembled, necessitating the use of jigs, tools, and fixtures to improve assembly efficiency, accuracy, and precision. We developed a range of assembly aids employing both traditional machining techniques and 3D printing to support all stages of the fabrication process. Many are vacuum connected to hold parts securely during gluing. Each unique target geometry requires a tailored assembly approach, and setups taking advantage of off-the-shelf and custom tools allow us to build targets that adhere to the tight tolerances and specifications required for successful experiments. This poster highlights a selection of these tools, focusing on how they support target assembly.
