To detect such a tiny force, the NIST team confined about 60 ultra-cold beryllium ions in a device called a Penning trap, which USES magnetic and electric fields to imprison charged particles.

为了测出如此微小的力，国家标准和技术学会的团队将大约60个超冷铍离子装在一个叫做“潘宁陷阱”的装置中，该装置是利用磁场和电场禁锢带电粒子的。

Last year ALPHA used a magnetic trap to hold on to antihydrogen atoms for a record 16 minutes.

Since they were first made in 1995, Bose-Einstein condensates have become commonplace as experimental tools. (They are particularly valued for their ability to slow the speed of light all the way down to zero.) Dr Steinhauer and his colleagues created a condensate out of a gas of rubidium atoms held in a magnetic trap.
