The superconducting electron accelerator S-DALINAC delivers a beam with a maximum energy of 130 MeV and beam currents up to 60 µA which is used for experiments in nuclear and astrophysics. In this talk an overview of the actual status and the latest upgrades is given.
To increase the injector energy up to 14 MeV and the current up to 150 µA new cavities and couplers for rf power up to 2 kW have been built and a new cryostat module has been designed.
To decrease the energy spread of the beam a non-isochronous recirculating scheme is planned and first results of the simulations are presented.
In order to reach the design Q factor one of our cavities was sent to Jlab for preparation and measuring of the maximum reachable Q value after a standard CEBAF treatment.
