The LLNL z-pinch ion probe experiment (ZIPX)

Summary form only given. Dense Plasma Focus (DPF) Z-pinches are copious sources of radiation including neutrons, x-rays, and MeV level electron and ion beams. Energetic protons and deuterons up to 10 MeV have been observed from ~cm long pinches indicating average acceleration gradients up to 1 GV/m. Corresponding electron beams with lower particle energy are also emitted. These beams contribute significantly to the neutron and x-ray output of the device. However, the mechanisms behind these gradients are not completely understood and hence a true predictive capability required for optimization or application is not currently available. At LLNL we are assembling a DPF experiment with a unique 4 MV ion probe beam designed to measure these gradients directly and to examine the possibility of using the DPF as a high-gradient acceleration stage. These unique data along with fully kinetic simulation of the DPF z-pinch will form an integrated simulation and experimental approach to understanding the DPF. In this poster we will review the design, construction, and initial operations of a 4 kJ modular DPF. We will also discuss how the probe beam will be used to measure the acceleration gradients in the plasma.
