摘要

研究岔流器脱离过程以及等离子体动力学和原子物理学过程的相关复杂相互作用,对于未来的聚变反应堆至关重要。虽然有简化的分析模型来解释脱离的一般特征,但它们的预测能力有限,通常需要复杂的二维(2D)甚至三维(3D)代码来提供憩室的自洽图像。作为中间步骤,一维(1D)刮除层(SOL)模型尤其具有洞察力,因为其动力学特性已被大大简化,同时仍能自洽地包含各种起作用的源和汇项,以及其他重要效应(如流动)。这些代码可用于揭示发生作用的物理学原理、执行快速参数扫描或解释实验。在本文中,我们将介绍 SPLEND1D(Simulator of PLasma ENabling Detachment in 1D)代码:一种快速、通用的一维 SOL 模型。我们将详细介绍 SPLEND1D 所实现的模型。然后,我们利用该代码探索托卡马克 à 配置变量典型参数的各种脱离物理要素,包括原子物理以及功率和动量损失背后的其他过程,并探索模型的各种假设和自由参数。

SPLEND1D, a reduced one-dimensional model to investigate the physics of plasma detachment
Studying the process of divertor detachment and the associated complex interplay of plasma dynamics and atomic physics processes is of utmost importance for future fusion reactors. While simplified analytical models exist to interpret the general features of detachment, they are limited in their predictive power, and complex two-dimensional (2D) or even three-dimensional (3D) codes are generally required to provide a self-consistent picture of the divertor. As an intermediate step, one-dimensional (1D) models of the scrape-off layer (SOL) can be particularly insightful as the dynamics are greatly simplified, while still self-consistently including various source and sink terms at play, as well as additional important effects such as flows. These codes can be used to shed light on the physics at play, to perform fast parameter scans, or to interpret experiments. In this paper, we introduce the SPLEND1D (Simulator of PLasma ENabling Detachment in 1D) code: a fast and versatile 1D SOL model. We present in detail the model that is implemented in SPLEND1D. We then employ the code to explore various elements of detachment physics for parameters typical of the Tokamak à Configuration Variable, including the atomic physics and other processes behind power and momentum losses, and explore the various hypotheses and free parameters of the model.
