最近报道了实验条件[G. Andresen，Phys. Rev. Lett. 98，023402（2007）]，其与捕获反氢原子的前景相关。实验条件的分析表明，正电子空间电荷可以有一个重要的影响。具有适合反氢捕获的能量的反质子的比例可以通过正电子空间电荷的存在引起的漂移而减少。
Experimental conditions have recently been reported [G. Andresen, Phys. Rev. Lett. 98, 023402 (2007)] that are relevant to the prospect of trapping antihydrogen atoms. An analysis of the experimental conditions indicates that positron space charge can have an important effect. The fraction of antiprotons that have an energy suitable for antihydrogen trapping can be reduced by drifts caused by the presence of positron space charge.
