Abstract :
The authors consider focusing of charged particles in the two-electrode electromagnetic mirror with rotational symmetry whose cylindrical electrodes also act as magnetic electrodes.
ations for different ratios of magnetic and electric components of the electromagnetic field have been made. The region in variations of geometrical and electrical mirror parameters where the third-order aberration vanishes to zero has been detected.
