反质子和质子的惯性质量已经被我们在CERN的TRAP合作测量到相同，精确度为4 × 10−8。采用了两个关键的实验进展，具有更广泛的适用性质谱。一个高精度的圆柱形陷阱与开放端盖电极允许自由进入陷阱中心的粒子加载，和一个自屏蔽超导超导磁共振系统消除在环境磁场的波动。
The antiproton and proton inertial masses have been measured to be the same to a fractional accuracy of 4 × 10−8 by our TRAP collaboration at CERN. Two key experimental advances were employed which have a wider applicability for mass spectroscopy. A high-precision cylindrical trap with open-endcap electrodes allows free access to the trap center for particle loading, and a self-shielding superconducting solenoids system cancels fluctuations in the ambient magnetic fields.
