Magnetic energy filter |
摘要 |
<p>A compact magnetic energy filter having at least four magnetic fields to deflect the trajectory of an electron beam from the entrance window to the exit slit. A rotational symmetry axis is located midway between the second and third magnetic fields. The magnetic fields on the opposite sides of the rotational symmetry axis are opposite in polarity.</p> |
