摘要:

在HL-2A装置上研制了用于测量等离子体密度分布的两套幅度调制微波反射仪。微波反射仪采用时间延迟法。这两套微波反射仪有不同的频率范围(26.5~40GHz和40~60GHz),它们所对应的密度测量范围是(0.84~1.98)×1019m-3和(1.98~4.47)×1019m-3。时间分辨率可达1ms,空间分辨率约为5mm。

关键词: HL-2A装置, 微波反射仪, 幅度调制, 密度分布

Abstract:

Two amplitude modulation microwave reflectometry systems based on time-delay method with scanning microwave source are designed for plasma density profile measurement on HL-2A tokamak. These two microwave reflectometors have different frequency ranges (26.5~40GHz, 40~60GHz) and they are suitable for measuring the plasma density (0.84~1.98)×1019m-3 and (1.98~4.47)×1019m-3 respectively. Temporal resolution is 1ms and spatial resolution is about 5mm.

Key words: HL-2A tokamak, Microwave reflectometry, Amplitude modulation, Density profile
