Abstract

Space charge waves in electron beams affect both the sum signal from pickup electrodes and the beam position measurements. The lowering of the sum signal can drastically decrease the precision of the measurements. If the wave is asymmetric, the space charge modulation can propagate transversally and compromise the accuracy of the position measurements.
