内容記述 |
Ion beams with micrometer-order spot size, so-called “microbeams,” have been utilized in a variety of fields. These include the biological response of radiation in cells and the single event effects of a semiconductor, etc. On the other hand, certain applications, such as the creation of a color center in a diamond, require an ion beam with not only the higher precision of a nanometer-order diameter but also the ability to implant ions one by one. The ion machine gun (IMG) is the possible choice for the realization of this distinctive ion beam. It is mainly composed of a linear Paul trap (LPT) and Doppler-cooling lasers. Ions laser-cooled to nearly absolute zero in the LPT reach a “Coulomb crystalline state.” If we extract ions in this state without heating, a unique ion beam can be attained. Most ion species, even if they cannot be directly laser-cooled, can be cooled sympathetically and crystallized through Coulomb collisions with laser-cooled ions simultaneously confined in the LPT. At Hiroshima University, we conduct proof-of-principle experiments of the IMG using laser-cooled calcium ions and sympathetically cooled nitrogen ions. Here we discuss the fundamental principle and experimental results of this study. |
