Goal of this chapter is to learn how we model the electron motions in

... the luninous traces. When the electron beam coincides with the luminous traces, only half of the circle is observable. The radius of the circle is then 2, 3, 4 or 5 cm. For detailed description of the narrow beam tube, please refer to the operating instructions. If the trace has the form of a helix ...
