... If we consider the force F = qE acting on a particle in the presence of some electrical potential energy Uel, then we have qE = - grad Uel . Dividing by q gives E = - grad Uel/q . But, the electrical potential energy per unit charge is the 'electric potential', V ! So E = - grad V = - V . This rela ...

... here) and that it does not depend on the sign of the charge. Thus, electrons and positrons would be deflected in exactly the same way in such a system. If the ExB filter and source end of the beam are floating, constant beam energy may be used for deflection, while retaining variable beam energy for ...
