表面电极阱冷离子亮源

Bright Source of Cold Ions for Surface-Electrode Traps

Marko Cetina, Andrew Grier, Jonathan Campbell, Isaac Chuang, Vladan Vuletic

摘要:

我们在表面电极的Paul阱中通过激光冷却原子的光电离产生大量低能离子。$4\times10^{5}$ Yb $^{+}$离子/s的同位素选择性陷阱加载速率超过通过原子束的光电离(电子碰撞电离)获得的速率四(六)个数量级。浅至0.13 eV的陷阱很容易用这种技术加载。离子被限制在与激光冷却原子相同的空间区域内,这将允许实验研究冷离子与冷原子或玻色-爱因斯坦凝聚体之间的相互作用。

英文摘要:

We produce large numbers of low-energy ions by photoionization of laser-cooled atoms inside a surface-electrode-based Paul trap. The isotope-selective trap loading rate of $4\times10^{5}$ Yb$^{+}$ ions/s exceeds that attained by photoionization (electron impact ionization) of an atomic beam by four (six) orders of magnitude. Traps as shallow as 0.13 eV are easily loaded with this technique. The ions are confined in the same spatial region as the laser-cooled atoms, which will allow the experimental investigation of interactions between cold ions and cold atoms or Bose-Einstein condensates.
