    "abstract": "Bunches of high charge (up to 10 nC) are compressed in length in the CTF II\nmagnetic chicane to less than 0.2 mm rms. The short bunches radiate coherently\nin the chicane magnetic field, and the horizontal and longitudinal phase space\ndensity distributions are affected. This paper reports the results of beam\nemittance and momentum measurements. Horizontal and vertical emittances and\nmomentum spectra were measured for different bunch compression factors and\nbunch charges. In particular, for 10 nC bunches, the mean beam momentum\ndecreased by about 5% while the FWHM momentum spread increased from 5% to 19%.\nThe experimental results are compared with simulations made with the code\nTraFiC4.",
