Asked by OIan

A source of ions at point O produces a slightly diverging beam with half-angle of divergence α0≪1. In order to collimate (re-focus) the beam, one can apply a uniform magnetic field along the z-axis (see the figure below). If all the ions have the same initial velocity and specific charge qm, the beam focuses at point A, again at point B and so on. Assuming that qm=10^5C/kg , B=10^−3T and v=100m/s find the distance
