Dense plasma focii (DPFs) are appealing as energy efficient sources of short pulses ions, neutrons, and x rays. The output these is expected to scale with input current (I4), but has been shown drop at the MA level [S. K. H. Auluck, “On failure neutron yield scaling in dense focus,” Phys. Plasmas 30, 080701 (2023)]. New results on MegaJOuLe Neutron Imaging Radiography DPF showed production agreement beyond previously observed drop. This work provides insight into pinch formation a reports...
Nuclear fusion is a potential source of carbon-free electricity with many concepts in development. The Portable and Adaptable Neutron Diagnostics for Advancing Fusion Energy Science (PANDA-FES) suite has been deployed since 2021 to measure neutron yield, energy, spatiotemporal location at two different Z-pinch devices. This diagnostic can be used variety facilities pursuing the magnetic, inertial, magneto-inertial regimes. These regimes have wide range time scales from less than 100 ns few...
Astrophysical flows may be studied by reproducing similar conditions using a coaxial plasma accelerator operating in the deflagration regime (or accelerator). This allows for recreation and investigation of dynamics present complex highly coupled systems at laboratory scale. We report on measurements density, temperature, potential velocity found quadruple Langmuir probe (QLP) such form Stanford Coaxial High ENerGy (CHENG) device with multiple gases – specifically argon, nitrogen hydrogen....
