Phys. Rev. Lett. 84, 658–661 (2000)Emittance Growth during Bunch Compression in the CTF-IIReceived 30 March 1998; published in the issue dated 24 January 2000 Measurements of the beam emittance during bunch compression in the CLIC Test Facility (CTF-II) are described. The measurements were made with different beam charges and different energy correlations versus the bunch compressor settings which were varied from no compression through the point of full compression and to overcompression. Significant increases in the beam emittance were observed with the maximum emittance occurring near the point of full (maximal) compression. Finally, evaluation of possible emittance dilution mechanisms indicates that coherent synchrotron radiation was the most likely cause. © 2000 The American Physical Society URL:
