Status and Advancements towards Commissioning of the S-DALINAC Injector Upgrade* — •Simon Weih, Michaela Arnold, Joachim Enders, and Norbert Pietralla — Institut für Kernphysik, TU Darmstadt, Darmstadt, Germany

A capture cavity for non-ultra relativistic electrons (β = 0.86) will be installed at the injector of the superconducting Darmstadt electron linear accelerator (S-DALINAC) [1] to achieve the beam quality required for the currently investigated multi-turn ERL mode and to re-enable an operation of the spin-polarized gun. After the finalization of the mechanical cavity processing, the latest completed work packages of the project include a hydrogen bake-out, field-flatness tuning, final RF surface preparation, and testing of the tuner components. In addition, a new diagnostics beamline upstream of the capture cavity was recently installed and commissioned. We will report on these latest advancements towards the commissioning of the upgraded injector.
