摘要：
本文报道了一种配备可互换探针头的多功能高速往复驱动系统（HRDS）的研制，用于表征 ADITYA-U 托卡马克的边缘等离子体区域。该往复式探针驱动系统由 Langmuir 探针头和磁探针头组成，经过设计、制造、安装和运行，用于研究燃料/杂质气体的传播范围及其对最后闭合磁面（LCFS）内侧远边缘区域等离子体动力学的影响。HRDS 由一台高精度、易控制、动态的无刷永磁同步伺服电机驱动，并由 PXI 指令控制器操作。该系统可远程操作，并允许逐炮精确控制探针头的速度、加速度和行进距离，从而便于根据实验需求无缝控制操作。利用该系统所包含的 Langmuir 探针线性阵列，对等离子体密度、温度、电位及其涨落的测量表明，燃料气体喷注会影响 LCFS 内侧直至 3 至 4 cm 范围内的这些平均参数和涨落参数。将磁探针阵列连接到该系统后，实现了对 LCFS 内侧磁涨落的测量。HRDS 系统已全面投入运行，并成为 ADITYA-U 托卡马克的重要诊断工具。
英文摘要：
This article reports the development of a versatile high-speed reciprocating drive system (HRDS) with interchangeable probe heads to characterize the edge plasma region of ADITYA-U tokamak. This reciprocating probe drive system consisting of Langmuir and magnetic probe heads, is designed, fabricated, installed, and operated for studying the extent of fuel/impurity gas propagation and its influence on plasma dynamics in the far-edge region inside the last closed magnetic flux surface (LCFS). The HRDS is driven by a highly accurate, easy-to-control, dynamic, brushless, permanently excited synchronous servo motor operated by a PXI-commanded controller. The system is remotely operated and allows for precise control of the speed, acceleration, and distance traveled of the probe head on a shot-to-shot basis, facilitating seamless control of operations according to experimental requirements. Using this system, consisting of a linear array of Langmuir probes, measurements of plasma density, temperature, potential, and their fluctuations revealed that the fuel gas-puff impact these mean and fluctuating parameters up to three to four cm inside the LCFS. Attaching an array of magnetic probes to this system led to measurements of magnetic fluctuations inside the LCFS. The HRDS system is fully operational and serves as an important diagnostic tool for ADITYA-U tokamak.
