Abstract: The use of coherent transition radiation autocorrelation methods to determinebunch length and profile information is examined with the compressed electronbeam at the BNL ATF. A bi-gaussian fit is applied to coherent transitionradiation auto-correlation data to extract the longitudinal currentdistribution. The effects of large transverse beam sizes are studied in theoryand compared to experimental results. A suitable form of the correction factoris derived for beams with large transverse-longitudinal aspect ratios.
