摘要

<正>In imaging experiments in ion-atom collisions, due to its small mass, the electron is easy to escape from the extraction electrostatic field, and this makes the complete collection difficult. In order to improve the solid angle for imaging of electrons, a uniform magnetic field is needed to restrict the electron trajectories .Usually, a pair of same coils, called Helmholtz coils, is employed to produce magnetic field. In our
