Another problem in a recuperator operation is a secondary electron emission from the recuperator collector induced by primarybeam electrons. The limiting experimental factor is how close reliable data can be determined near the primarybeam. Stray rays of the primarybeam can dominate the scattering. As the primarybeam rasters on the sample surface, the signal from the sputtered ions or secondary electrons is collected to form an image.
