The European transport simulator is a fusion machine simulator useful for making predictions of high-performance fusion plasmas, in particular for DT reactors. Recent developments introducing self-consistent simulations of combined RF + NBI heating schemes in which majority, minority and beam ions are simultaneously heated is documented. The predictive simulations are first validated by comparison with the experimental data on a DD JET baseline plasma. In order to prepare the next JET DTE2 experimental campaign, extrapolations of fusion performance on DT plasma from DD plasma are made with a particular focus on ion cyclotron resonance heating (ICRH) computation. Traditional ion cyclotron range of frequency heating models do not permit the study of Coulomb collisional interaction of various ion species simultaneously including neutral beam injection ions, and generally forces one to consider only minority populations. Accounting for multi-population interaction is made possible here by solving coupled sets of Fokker–Planck equations for all ion species adopting the non-linear collision operator for arbitrary distribution functions, accounting for effects, such as the self-collisions of majority (or large minority) populations. To answer the question whether H minority scheme or 3He minority ICRH scheme is better for boosting the DT fusion performance, minority concentration scans are produced.

JET-ILW 基线等离子体的欧洲传输模拟器建模:预测代码验证和 DTE2 预测

欧洲运输模拟器是一种聚变机模拟器,可用于预测高性能聚变等离子体,尤其是 DT 反应堆。最近的发展介绍了组合 RF + NBI 加热方案的自洽模拟,其中多数、少数和束离子同时加热。首先通过与 DD JET 基线等离子体的实验数据进行比较来验证预测模拟。为了准备下一个 JET DTE2 实验活动,从 DD 等离子体推断 DT 等离子体的聚变性能,特别关注离子回旋共振加热 (ICRH) 计算。传统的离子回旋加速器频率加热模型范围不允许同时研究各种离子种类的库仑碰撞相互作用,包括中性束注入离子,并且通常迫使人们只考虑少数群体。通过对所有离子种类采用非线性碰撞算子对任意分布函数求解耦合的 Fokker-Planck 方程组,考虑到诸如多数(或大少数)人口。回答问题是 H 少数计划还是 通过对所有离子种类采用非线性碰撞算子对任意分布函数求解耦合的 Fokker-Planck 方程组,考虑到诸如多数(或大少数)人口。回答问题是 H 少数计划还是 通过对所有离子种类采用非线性碰撞算子对任意分布函数求解耦合的 Fokker-Planck 方程组,考虑到诸如多数(或大少数)人口。回答问题是 H 少数计划还是3 He 少数 ICRH 方案更适合提高 DT 融合性能,产生少数浓度扫描。
