Benson, Stephen

We will discuss issues in the design, construction, and operation of accelerator lattices for use in ERLs. These include phase space quality preservation during generation, acceleration, and transport of high-power, high-brightness beams, appropriate configuration of beam properties for synchrotron radiation users across a spectral range spanning THz to X-ray, beam handling during energy recovery, management of instabilities and "stray" power arising from the beam's coupling to itself and to environmental impedances and wakes, and provision for large acceptance (through the use of appropriate nonlinear optics) for the control of degraded "spent" beam and suppression of halo-driven beam loss. Experience derived from Jefferson Lab operation of five ERLs - across an energy range of 20 MeV to 1 GeV - will be described.
