2.1 Study of the motion of a charged particle in a uniform magnetic field

The ions produced in the Nier-type source are extracted from it by means of an electrostatic field with velocity v [equation (7) ] and along a linear trajectory. They then enter a magnetic field characterized by a vector $\vec{B}$ delivered by an electromagnet. The electromagnet, weighing between 300 and 500 kg depending on the model, is made up of sectorized windings of copper...
