Numerical Experiments Providing New Insights into Plasma Focus Fusion Devices
Recent extensive and systematic numerical experiments have uncovered new insights into plasma focus fusion devices including the following: (1) a plasma current limitation effect, as device static inductance is reduced towards very small values; (2) scaling laws of neutron yield and soft x-ray yield as functions of storage energies and currents; (3) a global scaling law for neutron yield as a f...
متن کاملNumerical experiments on plasma focus pinch current limitation
Contrary to the general expectation that performance of a plasma focus would progressively improve with progressive reduction of its static inductance Lo, a recent paper suggests that there is in fact an optimum Lo below which although the peak total current increases progressively the pinch current and consequently the neutron yield of that plasma focus would not increase, but instead decrease...
متن کاملExperimental comparison of thermal neutron absorption cross section in nano and micro particles
The neutron collision cross-section is important in neutron use for a specific job, such as neutron therapy or even in nuclear reactors. In calculating computational codes such as MCNP, only information from the neutron-to-mass collision information contained in the computational code library is used, in the case of nanoscale particles in contrast to the mass of materials and / or particulate m...
متن کاملCurrent and neutron scaling for megajoule plasma focus machines
In a 2007 paper Nukulin and Polukhin surmised from electrodynamical considerations that, for megajoule dense plasma focus devices, focus currents and neutron yield Yn saturate as the capacitor energy E0 is increased by increasing the capacitance C0. In contrast, our numerical experiments show no saturation; both pinch currents and Yn continue to rise with C0 although at a slower rate than at lo...
متن کاملNeutron Imaging with Bubble Chambers for Inertial Confinement Fusion
One of the main methods to obtain energy from controlled thermonuclear fusion is inertial confinement fusion (ICF), a process where nuclear fusion reactions are initiated by heating and compressing a fuel target, typically in the form of a pellet that contains deuterium and tritium, relying on the inertia of the fuel mass to provide confinement. In inertial confinement fusion experiments, it is...
