electron trajectory
1.The equation of electron trajectory in a drifting tube filled with plasma under weak accelerating field was given in this paper , the traveling properties of electron beam in a and β area were also obtained. By means of digital calculation , the pattern of electron beam transmission was described as that electrons traveled like a wave around the equilibrium radius , and the period and scope of the wave were related to plasma parameters ,voltage and field inten- sity.
2.For example, a single electron in an unexcited atom is pictured classically as a particle moving in a circular trajectory around the atomic nucleus, whereas in quantum mechanics it is described by a static, spherically symmetric wavefunction surrounding the nucleus.
3.The minimal radius of the trajectory of electron beams is calculated. All in all, the electrical and geometrical parameters of the focusing system are calculated by using the CAD method and FORTRAN language. The focusing voltage of the unipotential lens is about -1960V, the radius of the EB spot on the workpiece is 1.212mm.
