Inertial electrostatic confinement (IEC) fusion represents rather old branch of controlled thermonuclear synthesis study (see [1-3] and references therein). Earlier, in particular, the yield of DD neutrons in a compact IEC scheme based on miniature nanosecond vacuum discharge (NVD) of low energy with deuterated Pd anode have been observed [4]. Further, detailed PIC simulation by the electrodynamic code KARAT have confirmed [5] that experiment with NVD is the realization of the IEC scheme [3]. The goal of this work is to present and discuss in detail the available experimental results on deuteron oscillations in the field of virtual cathode in NVD followed by pulsating DD neutron yield [6]. PIC simulations for some experimental regimes of pulsating neutron yield are shown, and comparison with available scheme of periodical oscillating plasmas spheres (POPS) [7] suggested earlier in Los Alamos for fusion at ICF scheme is given. The requirements needed to achieve a positive energy output for IEC scheme with oscillating ions (analogue of Lawson criterion [8] for breakeven) are discussed also [9].
