摘要:

Three electron beam deflection yoke models have been built to experimentally test the concept of compensated coil pairs. The yokes were placed in three different conductive tubes. Eddy‐current compensation was achieved, thus verifying earlier computations of the author. In particular, the uncorrected error of the cross‐axial field follows the reciprocal square root of the time following a change in deflection yoke current, and can be neutralized.
