Lattice of the Novosibirsk ERL | |
|
||
| The Novosibirsk ERL has rather complicated design. It can operate in three different modes and provide electron beam for three different FELs. Magnetic system of ERL includes one orbit in vertical plane which is used for the first terahertz FEL and four orbits in horizontal plane which are used for two other FELs. The second FEL is installed at the bypass of the second orbit and the third FEL is installed at the fourth orbit. The beam can be directed either to vertical or to horizontal orbits by switching of two round magnets. Two of four horizontal orbits have been already commissioned. Commissioning of the four-orbit ERL will start in near future. The FEL operation induces large energy spread in the beam therefore one has to pay special attention to the bending arcs lattice. In particular the arcs have to be achromatic and have to provide sufficient longitudinal dispersion. To compensate high-order chromatic aberrations one needs to use sextupoles. In this paper we present the simulation and experimental results of the Novosibirsk ERL lattice optimization. We also discuss longitudinal beam dynamics. | ||
| WG2013 | Multiturn ERL X-ray Source (MARS) Feasibility Study | 60 |

| Multiturn energy recovery linacs (ERL) looks very promising for making ERLs less expensive and more flexible, but have serious intrinsic problems. At this time only one multiturn ERL exists. This Novosibirsk ERL operates with two orbits and two free electron lasers now. The conception of Multiturn Accelerator-recuperator Radiation Source (MARS) was proposed in 1997 by G.N. Kulipanov, A.N. Skrinsky and N.A. Vinokurov. The use of the two-linac ERL (D. Douglas, 2001) makes multiturn operation much easier. The feasibility study for such ERL-based high brightness x-ray source is presented. | ||
