摘要：
The antiproton and proton inertial masses have been measured to be the same to a fractional accuracy of 4 x 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.
