Rapid advances in AI are reshaping software development through agentic workflows, significantly improving productivity and enabling previously impractical tasks. This talk will present our efforts to apply these technologies to application development, with approaches and lessons that may also benefit the broader accelerator community.
The SuperKEKB timing system has a unique configuration. It consists of both Event Timing System and White Rabbit. Besides, we utilize Event modules provided by MRF and SARI. We realized the complicated operation of SuperKEKB by making use of the characteristics of those modules.
Shanghai HIgh repetitioN rate XFEL and Extreme light facility (SHINE) interlock system comprises approximately 100 equipment cabinets and 10 000 interlock hardware signals. With the ongoing installation and commissioning of the SHINE facility, the scale of signals integrated into the interlock system continues to expand. This study aims to improve the efficiency of system development and...
It introduces the overall layout of the target station control system for CSNS Phase I, the EPICS access methods of each subsystem, and the main problems encountered during operation, as well as a brief introduction to the upgrade of CSNS Phase II.
The high-current multi-pulse linear induction accelerator operates in the burst mode. During a single operation, the control system must execute output control for multiple power supply groups, coordinate subsystem scheduling, manage timing triggers, implement fast protection, and monitor the entire process with software braking. Designed with a three-layer standard model architecture based on...
Accelerator-based Boron Neutron Capture Therapy (AB-BNCT) requires coordinated monitoring and safety evaluation across proton beam delivery, high-heat-flux target cooling, and the beam shaping assembly (BSA). While high-fidelity numerical simulations—such as MCNP6 for radiation transport and COMSOL Multiphysics for conjugate heat transfer—provide detailed physical insights, single-case...
In particle accelerator control systems, taking CAFeII and HIAF as examples, the accelerator uses mode management to dynamically rebuild device operation safety boundaries in different operating scenarios. It defines mode objects and configuration information, and IOC access security management is used to enforce access security constraints for mode objects under different modes. IOC access...
This paper presents the power supply control system developed for the High Energy Photon Source (HEPS). Over 2500 power supplies at 58 stations on the 1346 m storage ring are controlled via a hierarchical EPICS IOC structure with custom-built Modbus drivers. In the Booster, each power supply(Dynamic Ps) IOC runs in an isolated Docker container and the dynamic status data is captured at up to...
The China Spallation Neutron Source (CSNS) is a major facility for neutron science in China, currently operating at an average beam power of 170 kW, with a beam energy of 1.6 GeV and a repetition rate of 25 Hz. In 2024, the CSNS Upgrade Project (CSNS-II) was launched, introducing new instrumentation for the superconducting linac, RCS, and additional beamlines. In 2025, we have upgraded the...
We present an EPICS-native Bayesian optimization toolkit for automated beam commissioning at CSNS. Built on the Pyapas framework, the system integrates seamlessly with existing controls via EPICS Channel Access, treating all hardware setpoints and diagnostics as PVs. It supports both single-objective BO and multi-objective BO using qEHVI to optimize beam transmission and loss simultaneously. A...
This talk presents the design of a high-sampling-rate data acquisition system based on timing triggers. The system distributes timing trigger signals through a timing master and timing slaves to control data acquisition at the front-end devices. Power supply controllers are used as simulated front-end devices to generate sampled data. The data are buffered in fixed time windows according to...
Autonomous beam tuning of a tandem accelerator requires the coordinated control of multiple beamline devices and the continuous processing of beam diagnostic information. In the 2×6 MV tandem accelerator, the beam transport system consists of multiple electrostatic and magnetic elements distributed across several beamlines, resulting in a complex and highly coupled tuning problem. To support...
Beamline operation at the High Energy Photon Source (HEPS) requires the integration of control systems, experimental data, operational knowledge, and data-analysis tools. This work presents an intelligent agent-assisted framework for HEPS beamline operations based on locally deployed Large Language Models (LLMs) and the Osprey agent platform. The framework connects the language model with...
超导直线加速器涉及大量电源、射频及束流控制设备，运行参数分布于三十多个控制界面中，且不同子系统之间存在状态依赖。为解决超导直线加速器检修、调束及状态切换中参数分散、跨子系统执行顺序复杂和恢复结果难以统一确认等问题，构建了基于实验物理和工业控制系统（EPICS）与Phoebus保存与恢复（SAR）的模式驱动参数快照管理与恢复方法。该方法面向电源、低电平射频、定时、机器保护和束流允许五个子系统，建立目标模式与参数组、状态快照、执行阶段及校验规则的映射，通过分阶段调度和阶段内并行写入完成参数恢复，并结合回读校验、自动重试和异常处理形成闭环。在实际控制环境中开展恢复性能、20次重复执行及异常测试。结果表明，各子系统参数均能按既定阶段完成恢复与校验，多次执行的结果一致且耗时波动较小。该方法实现了多子系统参数恢复的统一组织与确认，提高了模式切换的可控性和异常可追溯性。
