摘要: In a low energy (2.3 kJ) Mather-type deuterium plasma focus, neutron and charged particle emission is investigated by using time-resolved detectors time-integrated pinhole imaging camera. The images demonstrate the varying influence of magnetohydrodynamic (MHD) instabilities vis-a-vis filling pressure. production mechanism at play strongly depends upon At lower pressure, column highly unstable due to MHD found be with fluence anisotropy exceeding 3.5. optimum pressure (2.5 mbar for this system), an almost stable dense about 17 mm3 volume formed 5 mm away from anode, its highest lowest. higher stable, although it moves anode like jet may then called moving boiler. case, lowered compared value increased. data suggest beam-target trapped gyrating particles jetlike boiler pressure.In compar...
