Division Spotlight
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

To explore the generation and extraction of negative ions for neutral beam injection, a prototype radio-frequency (RF)–driven negative ion source is designed at the test facility, which is under construction at the Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP). The control system provides beam pulse set up, remote supervision, plant control, timing synchronization, data management, and interlock and protection for the RF negative ion source. It plays an important role in negative ion source operation. The negative ion source prototype is currently in the development phase, involving more than 20 plant units. To match the requirements of control, data acquisition, and protection for different plant units, the plant control loop time is designed within the range of 10 μs to 100 ms, timing synchronization accuracy is 1 μs, the maximum sampling interval for data acquisition is 10 ms, the volume of data storage is tens of terabytes/year, and the interlock and protection response time is designed within the range of 10 μs to 100 ms. This paper describes the conceptual design of the control system for the prototype RF-driven negative ion source at the ASIPP, discusses the system requirements and the specifications for the control system, and shows the present status of system integration.
