最近，随着外差辐射计的升级，欧洲联合环形（JET）电子回旋辐射诊断的能力得到了扩展。通道数量增加了一倍，达到96个通道，由于谐波重叠，在JET使用的几乎所有磁场值（1.7 T<BT<4 T）下，X模式的频率间隔对应于2.6 m），同时保持了以前系统的高灵敏度和光谱分辨率。在本文中，概述了升级的辐射计的沿着与一些结果显示其性能。
The capabilities of the Joint European Torus (JET) electron cyclotron emission (ECE) diagnostics have recently been extended with an upgrading of the heterodyne radiometer. The number of channels has been doubled to 96 channels, with a frequency separation corresponding to 2.6 m for the X-mode due to harmonic overlap) at almost all magnetic field values used at JET (1.7 T<BT<4 T), while maintaining the high sensitivity and spectral resolution of the previous system. In this paper an overview of the upgraded radiometer is presented along with some results showing its performance.
