Abstract

TAE Technologies' newly constructed C-2W experiment aims to improve the ion and electron temperatures in a sustained field-reversed configuration plasma. A suite of Thomson scattering systems has been designed and constructed for electron temperature and density profile measurements. The systems are designed for electron densities of 1 × 10 cm to 2 × 10 cm and temperature ranges from 10 eV to 2 keV. The central system will provide profile measurements of T and n at 16 radial locations from r = -9 cm to r = 64 cm with a temporal resolution of 20 kHz for 4 pulses or 1 kHz for 30 pulses. The jet system will provide profile measurements of T and n at 5 radial locations in the open field region from r = -5 cm to r = 15 cm with a temporal resolution of 100 Hz. The central system and its components have been characterized, calibrated, installed, and commissioned. A maximum-likelihood algorithm has been applied for data processing and analysis.

摘要

TAE技术公司新建的C - 2W实验旨在提高持续反向场构型等离子体中的离子温度和电子温度。已设计并构建了一套用于电子温度和密度剖面测量的汤姆逊散射系统。这些系统设计用于电子密度范围为1×10厘米至2×10厘米，温度范围为10电子伏特至2千电子伏特。中央系统将在从r = - 9厘米到r = 64厘米的16个径向位置提供T和n的剖面测量，对于4个脉冲，时间分辨率为20千赫兹，对于30个脉冲，时间分辨率为1千赫兹。喷流系统将在开放场区域从r = - 5厘米到r = 15厘米的5个径向位置提供T和n的剖面测量，时间分辨率为100赫兹。中央系统及其组件已进行了特性表征、校准、安装和调试。一种最大似然算法已应用于数据处理和分析。
