  At DESY, an upgrade of the PETRA III synchrotron light source towards a fourth-generation, low emittance machine PETRA IV is currently being actively pursued. The basic concept of the control system of PETRAIV is to exploit synergies between all accelerator facilities operated by DESY. The key figures of PETRAIV’s new accelerator control system include the DOOCS control system framework, high-end MTCA.4 technology compliant hardware interfaces for triggered, high-performance applications and hardware interfaces for conventional slow-control applications compliant with industrial process control standards such as OPC UA, and enhanced data acquisition and data storage capabilities. In addition, the suitability of standards for graphical user interfaces based on novel Web application technologies will be investigated. Finally, there is a general focus on improving quality management and quality assurance measures, including proper configuration management, requirements management, bug tracking, software development, and software lifetime management. The paper will report on the current state of development.

  This contribution traces the development of DESY’s control system DOOCS from its origins in 1992 to its current state as the backbone of the European XFEL and FLASH accelerators and of the future Petra IV light source. Some details of the continual modernization and refactoring efforts on the 1.5 million line C++ codebase are highlighted.

  At DESY an upgrade of the PETRA III synchrotron light source towards a fourth-generation, low emittance machine PETRA IV is currently being actively pursued. The realization of this new machine implies a new design of the timing and synchronization system since requirements on beam quality and controls will significantly change from the existing implementation at PETRA III. The technical design phase of the PETRA IV project is in mid-phase and supposed to deliver a Technical Design Report by end of next year. The conceptual layout of the timing system will follow the successful MTCA.4-based approach as in use at the European XFEL. It will be enhanced to meet the requirements of a synchrotron facility and its booster and linac pre-accelerators. We present general concepts of the timing system, its integration into the control system as well as first specifications of the MTCA.4-based hardware components.
