In this paper, we propose a collective Thomson scattering diagnostic for fast ion measurements for the gas-dynamic trap (GDT) facility at the Budker Institute. The diagnostic utilizes 54.5 GHz gyrotron usually used for electron cyclotron resonance heating as a source of probe radiation and is aimed at reconstruction of distributions over transverse and longitudinal velocities of NBI-driven ions in the plasma core. Here we present a feasibility study of this concept.

GDT 开放式磁阱的集体 Thomson 散射诊断

在本文中，我们为 Budker 研究所的气体动态阱 (GDT) 设施提出了一种用于快速离子测量的集体 Thomson 散射诊断方法。该诊断利用通常用于电子回旋共振加热的 54.5 GHz 陀螺仪作为探测辐射源，旨在重建等离子体核心中 NBI 驱动离子的横向和纵向速度分布。在这里，我们提出了这个概念的可行性研究。
