我们报道了离子库仑晶体在具有存储环约束的线性保罗阱中的稳定性实验。在这种类型的阱中，带电粒子的横向动力学类似于快速光束通过具有周期性、磁交替梯度约束的通道。实验观察到的静止晶体的稳定性条件与当前的晶体等离子体和光束理论非常吻合。
We report experiments on the stability of ion Coulomb crystals in a linear Paul trap with storage-ring-like confinement. The transverse dynamics of charged particles in a trap of this type is analogous to that of a fast beam traveling through a channel with periodic, magnetic alternating gradient confinement. The experimentally observed stability conditions for stationary crystals comply remarkably well with current theory of crystalline plasmas and beams.
