Oscillating Plasmas for Proton- Boron Fusion in Miniature Vacuum Discharge

Figure 4

Concentrations of charges at selected points of the anode space on time at Z = 2.5 cm (PiC simulations for an applied voltage U = 100 kV with a front ∆t_f = 1 ns): (a) r = 0.1 cm and (b) r = 0.0 cm. The blue curves are electrons (b), the red ones are protons (r), and the yellow ones are boron ions (y) with a charge of Z_B = +3. The related values of total density of charges, or function μ(t) = −n_e(t) + n_p(t) + Z_Bn_B(t), are given at (c) and (d) for radial points r = 0.1 cm and r = 0.0 cm, correspondingly (see text). The energy of electrons as a function of their position along the discharge radius is shown in the Figure 4(a) inset (r_VC ≈ 0.1 cm, see Figure 1(a) also).
