Workshop on High Average Power & High Brightness Beams UCLA, Los Angeles, CA, November 8 – 10, 2004 Results of Parmela simulation for 1 nC e-bunch from the cathode to the end of the linac: black dashed curve is for a round beam passing without bends; blue curves are for a compensated chicane, red curves are for Zigzag merging system. In contrast with where horizontal emittance suffers some traditional chicane growth as result of the bending trajectory, the Z-system (zigzag) the emittances are equal to each other and are very close to that attainable for the straight pass. Chicane and Zigzag merging systems
