提出了一种强聚焦存储环，用于对 |a> 和 |b> 超精细态中性自旋极化氢原子的碰撞气体进行长期磁约束。该陷阱利用气体原子磁矩与静磁场的相互作用。激光冷却和蒸发冷却可用于增强限制并抵消粘性加热的影响。该陷阱的一个重要应用是实现玻色-爱因斯坦凝聚。
A strong-focusing storage ring is proposed for the long-term magnetic confinement of a collisional gas of neutral spin-polarized hydrogen atoms in the |a〉 and |b〉 hyperfine states. The trap uses the interaction of the magnetic moments of the gas atoms with a static magnetic field. Laser cooling and evaporative cooling can be utilized to enhance the confinement and to offset the influence of viscous heating. An important application of the trap is to the attainment of Bose–Einstein condensation.
