128 通道二维电子回旋发射成像系统收集 TEXTOR 托卡马克上 T(e) 剖面和波动的时间分辨 16x8 图像。电子回旋发射成像 (ECEI) 正在经历重大变革，有望彻底改变其功能，并使其功能远远超出迄今为止所取得的成就。其中包括开发具有更高灵敏度天线的微型透镜阵列配置、新的本地振荡器泵浦方案、增强的电子回旋共振加热屏蔽以及具有垂直变焦能力的高度灵活的光学设计。新的 ECEI 电子设备还正在开发水平变焦和光斑尺寸（射频带宽）功能。正在开发一个接口模块，用于远程控制新型 ECEI 仪器的所有关键功能，其中许多功能可以在等离子体放电期间进行更改，以实现最大的灵活性。
A 128 channel two-dimensional electron cyclotron emission imaging system collects time-resolved 16x8 images of T(e) profiles and fluctuations on the TEXTOR tokamak. Electron cyclotron emission imaging (ECEI) is undergoing significant changes which promise to revolutionize and extend its capabilities far beyond what has been achieved to date. These include the development of a minilens array configuration with increased sensitivity antennas, a new local oscillator pumping scheme, enhanced electron cyclotron resonance heating shielding, and a highly flexible optical design with vertical zoom capability. Horizontal zoom and spot size (rf bandwidth) capabilities are also being developed with new ECEI electronics. An interface module is under development to remotely control all key features of the new ECEI instrument, many of which can be changed during a plasma discharge for maximum flexibility.
