| Abstract: |
Coherent optical transition radiation (COTR) from femtosecond electron bunches is simulated using an earlier proposed model. It is shown that partial screening of the COTR field followed by focusing with a lens allows increasing the spatial resolution and makes it possible to measure transverse bunch sizes accurate within a few microns. It is demonstrated that the most reasonable lens screening ratio equals to 50%. Given this, it is possible to eliminate the ring-like structure typically observed on bunch images as a result of coherence. [ABSTRACT FROM AUTHOR] |
