“…Additionally, the electrons' momentum spread is sufficiently small along the entire accelerator so that the beam is kept within the momentum acceptance. The minimum ϵ is 630 eV/c in the case of the present results for the triple-turn ERL, compared to 1 eV/c for the double-turn ERL [4]. For the tripleturn ERL, a higher value results due to the increased number of restrictive conditions ('reach p 0,5 and p 0,6 ') compared to the double-turn ERL; although there is one additional degree of freedom (L T ) the same precision as in [4] can not be achieved.…”

“…Furthermore, sophisticated values for the longitudinal dispersion should be set per arc section in order to influence the longitudinal phase space properly. Therefore, beam-dynamics simulations prior to beam-tuning are necessary to find optimum values for these parameters [7,8]. Similar to [4], the simulations have been performed using the tracking software elegant [9] with an extended version of the code that was already used to realize the double-turn energy-recovery mode at the S-DALINAC [10].…”

“…For the simulations, an initial beam with momentum spread σ δ = 6.5 × 10 −4 and bunch length σ t = 0.36 ps was used. These parameters are identical to those used in [4] which allows a comparison to the double-turn ERL. Starting from a solution of the above mentioned problem, the first-order longitudinal dispersions of the injector arc, R 56,I , of the first recirculation beamline, R 56,F , of the second recirculation beamline, R 56,S , and of the third recirculation beamline, R 56,T , were varied according to [4,10] to find an optimum momentum spread.…”

“…By using superconducting cavities, the recovered energy can be efficiently stored in the electric field of the cavities, enabling low-loss reuse. The design of the S-DALINAC provides several operation modes; a single-turn as well as a double-turn ERL have been realized previously [3,4]. By increasing the turn number, the very same LINAC can be used to increase the maximum beam energy, E. In this way, multi-turn ERLs enable significant increase of beam power, P , since P ∝ E × I.…”

The electron accelerator S-DALINAC at TU Darmstadt was successfully operated in single- and double-turn energy-recovery mode. The latter was realized using a shared beam-transport where two beams are superimposed in the first recirculation beamline. Due to its current design, the S-DALINAC can be upgraded with reasonable effort to be operated in triple-turn energy-recovery mode with shared beam-transport. Here, two beams are superimposed in both the first and the second recirculation beamline. This mode is particularly challenging since it does not allow for on-the-fly beam tuning compared to a triple-turn energy-recovery mode with individual beam-transport. Therefore, the triple-turn energy-recovery mode requires precise determination of the accelerator setup obtained from beam-dynamics simulations prior to beam-tuning. First results of the necessary beam-dynamics simulations for this mode are presented.
