论文摘要
在3D混合动力学 - 纳图 - 纳图水力动力学巨型中，已经实施了合成快速离子损耗检测器（FILD）和成像重离子束探针（I-HIBP）。已经获得了这两个诊断的首次合成测量，用于用巨型模拟的中性束注射（NBI）驱动的Alfvéneigenmode（AE）。合成快速离子损失与AE振幅有很强的相关性。在相位空间中观察到这种相关性，在坐标中表示环形规范动量和能量。快速离子损失和受限群体的能量交换图与E'的恒定线（E'和p p移的线性组合。首先还针对模拟AE计算了I-HIBP合成信号，显示了约1 mm的划线中的位移，高于I-HIBP闪烁体的预期分辨率约为100μm。
A synthetic Fast-Ion Loss Detector (FILD) and an imaging Heavy Ion Beam Probe (i-HIBP) have been implemented in the 3D hybrid kinetic-magnetohydrodynamic code MEGA. First synthetic measurements from these two diagnostics have been obtained for neutral beam injection (NBI) driven Alfvén Eigenmode (AE) simulated with MEGA. The synthetic fast-ion losses show a strong correlation with the AE amplitude. This correlation is observed in the phase-space, represented in coordinates toroidal canonical momentum and energy. Fast-ion losses and the energy exchange diagrams of the confined population are connected with lines of constant E' , a linear combination of E and Pϕ . First i-HIBP synthetic signals also have been computed for the simulated AE, showing displacements in the strikeline of the order of around 1 mm, above the expected resolution in the i-HIBP scintillator of approximately 100 μm.
