雅典娜和ATRAP的合作最近创造了大量未被捕获的反氢原子。最常见的捕获反氢的方案是使用最小的-B陷阱。不幸的是，最小的B场很可能会破坏反氢成分、正电子和反质子的限制，这些成分本身就保存在双势垒的Malmberg-Penning陷阱中。文中讨论了失禁的原因，以及对最小B陷阱的修改可以缓解这一问题。
The ATHENA and ATRAP collaborations have recently created large numbers of untrapped anti-hydrogen atoms. The most commonly suggested scheme for trapping the anti-hydrogen is to use a Minimum-B trap. Unfortunately, the Minimum-B fields are very likely to destroy the confinement of the anti-hydrogen constituents, the positrons and anti-protons, which are themselves held in double-well Malmberg–Penning traps. The reasons for the loss of confinement, and modifications to the Minimum-B trap that may alleviate this problem, are discussed in this paper.
