内容記述 |
A single-ion implantation (SII) system combining a linear-Paul-trap ion source (LPT-IS) by laser cooling and a two-stage acceleration lens is developed to fabricate an array of nitrogen vacancy color center (NVC), which has attracted significant attention as a qubit. The fabrication of the NVC arrays requires the implantation of a single nitrogen molecule ion (N2+) from SII into a diamond specimen with 10-keV energy order and precision of several tens of nanometers or less. To satisfy this requirement, N2+ with very low emittance must be selectively extracted from LPT-IS. In this study, the selective extraction of N2+ by the magnitude and timing of the voltage applied to the end plate electrodes of a conventional LPT is investigated using the three-dimensional multiparticle simulation. The emittance of N2+ extracted from the LPT-IS is the lowest when N2+ is at the leading of an array of N2 and Ca+ in the string-like crystalline structure formed with sympathetic cooling. As the array of N2+ and Ca+ passes through the end plate electrode of the LPT-IS, a single N2+ can be extracted with the required energy and without degrading the emittance by increasing the voltage applied to the end plate electrode at the optimum timing. |
