摘要

兰州重离子加速器放射性次级束分离线一号线（Heavy Ion Research Facility in Lanzhou-Radioactive Ion Beam Line 1，HIRFL-RIBLL1）已运行多年，其电源控制系统因建设初期条件所限设计较为简单，加之近年来系统部件老化，已不能很好满足物理实验要求，迫切需要进行升级改造。新的电源控制系统针对现有问题，采用分布式架构，每台电源用一台高精度控制器就近控制。同时集成了二极磁铁磁场强度和所有电源输出电流的监控，并且利用滞环控制策略，实现了根据预设磁刚度自动调试电源的功能。新电源控制系统经过一年多来的几次实验调束验证，在调试精度、抗干扰性、易用性等方面满足了RIBLL1物理需求，大幅度提高了调束效率。

Abstract

Background

Radioactive Ion Beam Line 1 of Heavy Ion Research Facility in Lanzhou (HIRFL-RIBLL1) could not fulfill physical experiment requirement ideally due to the simple initial design of its power control system and components degradation in recent years.

Purpose

This study aims to reconstruct the power supplies system using new digital control techniques.

Methods

Distributed architecture

i.e.

one power supply under control of one precise controller closely

was adopted on the basis of Ethernet. Both magnetic field intensity of dipole magnets and output current of all power supplies were monitored. And automatic power supply steering according to presupposed magnetic rigidity was realized using the hysteresis control strategy.

Results

The reconstructed system is verified in one-year beam steering to have fulfilled the requirements like steering precision

anti-interference performance and usability and it can improve the steering efficiency greatly.

Conclusion

Network-based automatic power supply control system for HIRFL-RIBLL1 solves all problems existed in the previous system.
