摘要：

快速扫描气动探针已在HL- 2A 装置上用于对边缘等离子体参数的径向分布的测量, 特别是刮离层等离子体参数的特征长度和扰动的测量。该系统采用精密的气动气缸驱动带有探针组件的长驱动杆, 其最快速度可在60 ms 时间内水平扫描8 cm 的距离。探针信号测量具有1MHz 的快速时间响应和0. 04 mm 的空间分辨率。可靠地测量了HL- 2A 装置边缘电子温度和密度的时空分布。

Abstract:

A fast- scanning probe system has been installed in the HL-2A tokamak and is used to measure the edge and scrape-off layer ( SOL) plasma parameter profiles, especially the characterist ic length and fluctuations of local plasma parameters. The system has a compact pneumat ic cylinder and the pneumat ic cylinder can drive a long drive shaft with the probe array. The system can scan a horizontal distance of 8 cm in 60 ms. The SOL and edge plasma parameter profiles with spatial resolution 0. 04 mm have been obtained with a digital grating displacement measurement system.

Key words: A fast-scanning system, Digital grating displacement system, Pneumatic cylinder
