    Abstract: A method for profiling the magnetic fields of periodic permanent magnetic field structures as performed by using an electromagnetic solver to generate data fields representative of each individual magnet's contribution to the total vector potential field (110), determining the magnetization values for each magnet necessary to provide the desired total magnetic field (112) and superimposing individual vector potential fields to form a total vector potential field (113). Using the electromagnetic solver includes assuming unit magnetization for a selected magnet (120), setting the magnetization values of all of the other magnets to zero (122), setting the electromagnetic solver to use high resolution proximate the selected magnet and to use low resolution elsewhere (124), and using the electromagnetic solver to compute the vector potentials for all space for which the magnetic field is to be profiled (126). This process is repeated for each magnet of the periodic permanent magnets (128) so as to generate data files.

    Abstract: An electron source comprises cathode means and a permanent magnet perforated by a plurality of channels extending between opposite poles of the magnet. Each channel forms electrons received from the cathode means into an electron beam for guidance towards a target. The electrons sources has applications in a wide range of technologies, including display technology and printer technology.
