Litvinenko (BNL) Z-system for merging low emittance beams Chicane and Zigzag merging systems Laser Standard - Chicane ε x > ε y From the SC RF Gun 2.5 MeV Laser Separating magnet MeV from ERL Optimized - Z-system ε x = ε y δ = E E o ; E o δ const + no focusing θ i = 0; z i θ i = 0 i i Solenoid Solenoid δ = E E o E o ; δ δ o + κ z f (ς) (no focusing) θ i = 0; z i θ i = 0; z 2 i θ i = 0 i i i

In contrast with traditional chicane where horizontal emittance suffers some 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.
