In July 2000, a magnetic bunch compressor was installed in the APS linac as part of the LEUTL FEL project. This compressor was intended to test concepts for the bunch compressors that will be used in the LCLS. Hence, we have been experimentally characterizing the effects of coherent synchrotron radiation (CSR) as well as developing simulation codes to predict these effects. We report here on recent measurements and simulation results, which show good agreement. We also discuss plans for future experiments.
