Graphical cross section of the SPAN-E optics design. The green lines represent the curves of the deflectors, blue represents the top cap and upper outer hemisphere, yellow shows the spoiler section, and purple shows the inner hemisphere. The red curve is a representative travel path for electrons eligible to pass through the analyzer when the hemisphere (purple) is biased, the upper deflector is biased, the lower deflector is at ground, and both the spoiler and upper outer hemisphere (blue and orange) are also held at ground.
