  The Hefei Advanced Light Facility (HALF) is a 2.2-GeV 4th synchrotron radiation light source, which is scheduled to start construction in Hefei, China in 2023. The HALF contains an injector and a 480-m diffraction limited storage ring, and 10 beamlines for phase one. The HALF control system is EPICS based with integrated application and data platforms for the entire facility including accelerator and beamlines. The unified infrastructure and network architecture are designed to build the control system. The infrastructure provides resources for the EPICS development and operation through virtualization technology, and provides resources for the storage and process of experimental data through distributed storage and computing clusters. The network is divided into the control network and the dedicated high-speed data network by physical separation, the control network is subdivided into multiple subnets by VLAN technology. Through estimating the scale of the control system, the 10Gbps control backbone network and the data network that can be expanded to 100Gbps can fully meet the communication requirements of the control system. This paper reports the control system architecture design and the development work of some key technologies in details.

  The Hefei Advanced Light Facility (HALF) is a 2.2-GeV 4th synchrotron radiation light source, which is scheduled to start construction in Hefei, China in 2023. The HALF contains an injector and a 480-m diffraction limited storage ring, and 10 beamlines for phase one. The HALF historical data archiver system is responsible to store operation data for the entire facility including accelerator and beamlines. It is necessary to choose a high-performance database for the massive structured data generated by HALF. A fair test platform is designed and built to test the performance of six commonly used databases in the accelerator field. The test metrics include reading and writing performance, availability, scalability, and software ecosystem. This paper introduces the design of the database test scheme, the construction of the test platform and the future test plan in detail.

  The control system of the Hefei Light Source II (HLS-II) is a distributed system based on Experimental Physics and Industrial Control System. The alarm system of HLS-II is responsible for monitoring the alarm state of the facility and distributing the alarm message in time. The monitoring range of the alarm system covers the devices of HLS-II technical group and the server platform. Zabbix is an open-source software tool to monitor the server platform. Custom metrics collection is achieved by implementing external scripts written in Python and automated agent deployment discovers the monitored servers running with Zabbix agents. The alarm distribution strategy of the front end devices is designed to overcome alarm floods. The alarm system of HLS-II provides multiple messaging channels to notify the responsible staff, including WeChat, SMS and web-based GUI. The alarm system of HLS-II has been deployed since December 2022. The result shows the alarm system facilitates the operator to troubleshoot problem efficiently to improve the availability of HLS-II.
