Abstract:

t To improve the accuracy and usability of the superconducting electron cyclotron resonanceion sourcewith advanced design in Lanzhou (SECRAL), an upgraded version of the control system was designed andtested. This paper detailsthe architecture ofthe optimized control system and presentsthe results ofits usein the long-term operation of the accelerator. The control system software, based on Visual C++, was developed following the model-view-controller architecture design pattern. The data acquisition system was based on a field-programmable gate array integrated circuit. In addition, control strategieswere optimized for higher operational stability. The upgraded control system was tested with a U33? ion beam at SECRAL, where it provided a data acquisitiontime oflessthan 1 ms. The fast reactiontime and highprecision data processing during beam tuning verified the stability and maintainability of the control system.
