Work is now underway to improve the accuracy of the electron magnetic moment measurements by 10 to 100; that is, to an accurary of 1 part per trillion. At this level of accuracy, the magnetic bottle so crucial to previous measurements must be removed. In fact, intrinsic bottles due to the paramagnetism of the trap electrodes must be carefully canceled. A promising replacement for the magnetic bottle is the relativistic mass increase which acts like a magnetic bottle 20 times smaller than the one previously used but with no distortion of the magnetic field. The relativistic mass increase has been observed for 0. 5 ev electrons.
