Recalculation of the dispersion tracks of the recirculations at the S-DALINAC* — •Jonas Pforr, Michaela Arnold, Florian Hug, and Norbert Pietralla — Institut für Kernphysik, TU Darmstadt, Darmstadt, Germany

The S-DALINAC is a twofold recirculating superconducting electron linear accelerator operated at Darmstadt. The design-energy of 130 MeV could however not be reached in cw operation so far due to a lower quality factor of the superconducting cavities than originally expected.

In order to increase the possible beam energy in future the construction of a third recirculation is planned. Since this modification slightly changes the layout of the excisting recirculations as well, the beam dynamics in all recirculations had to be revised by simulations. In this context, the relation between the longitudinal disperison and the quadrupole gradients was studied, which is important for the non-isochronous operation of the S-DALINAC.

We present the latest simulations of the beam dynamics, where the results of the new recirculation are of particular interest.
