Development of a miniature 3 axis magnetic field sensor to predict the magnetic stray field influence on electron beams
Peter J. Oving

Cite as:

The desired form of electron beams is generally obtained by the use of magnetic fields in coils by focalisation, deflection, and other. The beam form is also influenced, due to incomplete shielding, by the magnetic environment, ...  read more
