Coherent edge radiation, emitted from the edges of chicane dipole magnets, has recently been observed at the Accelerator Test Facility at Brookhaven National Laboratory. Using the 60 MeV linac, a series of experiments has been performed to characterize the radiation, including measurements of the spectrum, angular distribution, and polarization. Details and results of the experiments and plans for future experiments are presented.

The presentation will cover recent experimental results on generation and measurement of the beams with the bunch lengthes from 0.3 to 500 fs at Brookhaven Accelerator Test Facility. Double beam structure is produced at 100 fs - 0.5 ps time scale using compression in the magnetic chicane - "dog leg" arrangement. The beam structure is characterized using interferometer and 6 mm long plasma wakefield channel with the controllable plasma density. Arbitrary number of 10-100 femtosecond microbunches is sliced out of 5 ps long beam using wire mesh. CSR interferometer is used for detailed characterization of the beams. Accuracy of the bunch length measurement using CSR energy is greatly improved for the 0.3 fs bunches by spectral measurements of multiple harmonics.
