Abstract

In this study, a design is proposed, based on theoretical calculations, to increase the density of deuterium in titanium beyond its initial value. The enrichment plan involves using deuterium plasma. The enrichment target is a copper disc coated with titanium. To implant deuterium ions into this target, the disc is immersed in deuterium plasma. The target is connected to a high power modulator and subjected to its negative voltage pulses. When the negative pulses are applied, deuterium ions accelerate toward the target, penetrating and implanting into it. Due to the low diffusion coefficient in titanium, the incident ions do not diffuse in quickly at first, so they accumulate near the target surface early in the implantation process. The diffusion equation describes the predicted distribution of ions inside the target, and it has been found that the deuterium concentration in titanium can be increased significantly within a few weeks, exceeding the initial value by several orders of magnitude.
