Status of the new capture section for the S-DALINAC injector* — •Simon Weih1, Michaela Arnold1, Dmitry Bazyl2, Joachim Enders1, Herbert De Gersem2, Wolfgang Müller2, and Norbert Pietralla1 — 1Institut für Kernphysik, TU Darmstadt, Darmstadt, Germany — 2Institut für Theorie Elektromagnetischer Felder, TU Darmstadt, Darmstadt, Germany
The first cavity of the superconducting section of the S-DALINAC [1] injector will be replaced by a new beta-adapted 6-cell structure in order to improve the electron bunch capture at an energy of 250 keV. To adapt the existing cryomodule to the new capture cavity, the tuner frame and other surrounding parts were modified. Beam dynamics simulations show that the beam quality downstream the injector strongly depends on the input bunch parameters. Therefore, a diagnostics setup at the end of the normal-conducting section of the injector is currently being planned. This setup will be used to characterize the beam in front of the capture section, supporting the future commissioning of the upgraded injector. This contribution will present the status of the foreseen improvements.
