The MJOLNIR platform: a versatile MA pulsed power facility*

The MegaJOuLe Neutron Imaging Radiography (MJOLNIR) platform at LLNL was commissioned in 2018 to investigate the viability of a dense plasma focus (DPF) as a source for dynamic radiography applications. In this work, we described recent experiments in which different anode shapes were fielded along with the introduction of inert dopant gases. Optical, x-ray, and neutron measurements from an extended suite of diagnostics will be presented. Furthermore, we present new capabilities to be added on the MJOLNIR platform, increasing experimental flexibility and allowing the investigation and mitigation of parasitic currents. Namely, a new cathode mount and a gas jet will be implemented to allow easy swapping of cathodes with different shapes and increase local gas density on-axis. The MJOLNIR platform can provide unique experimental capabilities to broader scientific communities that are interested in fundamental plasmas science and its applications outside of radiography. The MJOLNIR team is actively seeking potential external users.
