, 1989 Publisher Summary The term “Electron Beam Testing” means the testing of electrical properties of a circuit or an electron device by using the electron beam. The commercial electron beam tester uses the probing action of an electron beam, and it can resolve 0.1 μ m spatially and subnanosecond in time. Its voltage sensitivity reaches 10 mV.

Manipulating Twisted Electron Beams [PDF]
Physical Review Letters, 2017 A theoretical description of vortex electrons interacting with electric and magnetic fields is presented, based on Lorentz transformations. The general dynamical equations of motion of a twisted electron with intrinsic orbital angular momentum in an external field is derived.
