In this paper, an analysis of the space charge build up in the interelectrodic region of a velocity analyzer with cylindrical symmetry is performed using kinetic theory. Thus the present treatment includes temperature effects. Azimuth symmetry is also assumed. A detailed and comparative analysis, between planar and cylindrical electrodes, is carried out, showing the advantages of each kind of symmetries.
