Cryogenic Ion Trap for Minimization of Trapped Ion Loss
スポンサーリンク
概要
- 論文の詳細を見る
A cryogenic linear ion trap was developed for the minimization of the loss of trapped Be$^+$ ions. Buffer gas cooling as well as laser cooling for light element ions was tested in the cryogenic trap. The lifetime for the He-gas-cooled Be$^+$ ions was longer than 15 min with a liquid-He-cooled trap, although they are known to be difficult to cool with a buffer gas in a conventional trap. A laser-cooled ion crystal was maintained for approximately 30 min without any ion loss.
