Abstract:
The Helmholtz-Zentrum Berlin f¨ur Materialien und Energie (HZB) proposes to construct an ERL test facility [1]. To provide different operational modes for different scientific applications is one of the advantages of these new, linac-driven radiation sources. In contrast to the linear machine layouts of FELs, new challenges arise from incorporating the linac into a circular machine. One of them is the so called merger, a magnetic chicane that threads the low energy, low emittance, but high charge bunch from the gun into the recirculator. The preservation of the ambitious gun parameters and the flexibility to suit all user demands are the dominant design goals. Different design criteria and possible layouts are discussed and a preliminarymerger design is proposed.
