在这项工作中，我们提出了在JT-60SA先进托卡马克上安装多普勒反射计(DR)系统的可行性和实用性的研究。首先，我们在JT-60SA研究计划的背景下讨论它的科学范围。我们确定了一些领域，在这些领域中，DR将与完成所述计划非常相关，并概述了诊断的科学计划。然后，从若干设计假设出发，利用射线跟踪代码对若干相关场景进行了可行性研究，确定了DR安装的几何解，使岩芯和边缘都能在规定的波数范围内进行探测，从而达到了所提出的科学目标。最后，我们对概念设计的不同可能性(包括最小可行系统和基线系统)及其在部件和空间方面的要求进行了初步讨论。我们的结论是，可以使用一小部分水平端口进行可行的概念性设计，从而为其他诊断系统留出空间。
In this work we present a study on the viability and practicality of installing a Doppler reflectometer (DR) system in the JT-60SA advanced tokamak. First, we discuss its scientific scope in the context of the JT-60SA research plan. We identify a number of fields in which a DR would be very relevant for the accomplishment of said plan and outline a scientific program for the diagnostic. Then, starting from a number of design hypothesis, we use a ray tracing code to carry out a feasibility study for a number of relevant scenarios and identify a geometric solution for the installation of a DR such that both core and edge can be probed in the prescribed wave number range, thus achieving the proposed scientific objectives. Finally, we perform a preliminary discussion on the different possibilities for a conceptual design (including a minimum viable system and a baseline system) and their requirements in terms of components and space. We conclude that a viable conceptual design could be carried out using a small fraction of a horizontal port, leaving room for additional diagnostic systems.
