在本文中，我们提出了一种新的校准的JET实时偏振计的复振幅比技术和一种新的自验证机制的基础上实现的工作。这使得旋光测量可以轻松集成到JET等离子体密度控制（气体反馈控制）以及机器保护系统（中性束注入加热安全联锁）中。2014年JET活动期间成功使用了新增加的设备，预计从2015年活动开始，将在任何等离子体条件下（包括ITER相关情景）进行常规运行。这种操作模式提升了偏振测量作为未来聚变实验诊断工具的重要性。
In this paper, we present the work in the implementation of a new calibration for the JET real-time polarimeter based on the complex amplitude ratio technique and a new self-validation mechanism of data. This allowed easy integration of the polarimetry measurements into the JET plasma density control (gas feedback control) and as well as machine protection systems (neutral beam injection heating safety interlocks). The new addition was used successfully during 2014 JET Campaign and is envisaged that will operate routinely from 2015 campaign onwards in any plasma condition (including ITER relevant scenarios). This mode of operation elevated the importance of the polarimetry as a diagnostic tool in the view of future fusion experiments.
