dc.description.abstractTo improve beam quality, the DELTA storage ring (TU Dortmund) conducted a number of orbit-feedback developments in the past, including a successful fast local orbit feedback project. To enable hadron accelerators to benefit from this knowledge, a collaboration was formed between DELTA, the storage ring COSY (Forschungszentrum Jülich) and the SIS18 accelerator (GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt). The goals were the development of a global fast orbit feedback system for the DELTA storage ring, the development of a local feedback for the COSY electron beam cooler section and a global feedback for the SIS18 accelerator. This thesis describes the development and application of a universal position measurement system, usable for electron and hadron accelerators and targeted to fast orbit feedback applications, in the framework of this collaboration. The developed distributed system has input capabilities for electron or hadron beam position monitors and output options for feedback tasks and different control system connections. It is connected by a versatile communication structure. The developed common hardware platform is re-programmable and therefore usable as an input device as well as for feedback- or other measurement tasks. It delivers data at a constant data rate of 10 kHz, resulting in a target feedback-rate of up to 1 kHz. It was used to evaluate beam position data globally at DELTA, locally at SIS18 and locally at the COSY beam cooler section. At DELTA, the system forms the basis for a future fast orbit feedback system, which is expected to significantly increase the beam quality for synchrotron radiation based research as well as ongoing electron-beam/laser interaction experiments. The system can also be used as a high precision data source for the slow orbit feedback system in operation. The COSY measurements show the possibility of a local fast orbit feedback system at the storage ring's electron cooler. The data analysis of the SIS18 accelerator suggests the utilization of a feedback system to improve beam quality during ramping. The system's structure is expected to be utilized in a future SIS100 accelerator feedback.en
