Recently a new radiation protection interlock system has been established at the Darmstadt superconducting linear electron accelerator S-DALINAC [*]. It prevents the staff from entering radiation protection areas during operation and allows a systematic scanning of these areas for workers before running the accelerator. As an extension of the new interlock, a new dose rate monitoring system has been developed using PIN diodes and self-made ion chambers. These detectors will be used to perfom online dose rate measurements in order to switch automtically the status of illuminated radiation protection panels, which show the current level of protection area. Furthermore, they will be used to characterize systematically the radiation fluxes inside the accelerator facility and to support the beam diagnostics. The readout electronics consists ofμcontrollers with ethernet interfaces using TCP/IP based serial communication. The data acquisition is integrated into the EPICS based control system. First results of the commissioning will be presented.
