Neutral beam operations for JET TT and DT campaigns

Neutral beam injection (NBI) is a flexible auxiliary heating method for tokamak plasmas, capable of being efficiently coupled to the various plasma configurations required in the Tritium and mixed Deuterium–Tritium Experimental campaign 2 on the Joint European Torus (JET) device. High NBI power was required for high fusion yield and alpha particle studies and to provide mixed Deuterium–Tritium (D–T) fuelling in the plasma core, it was necessary to operate the JET NBI systems in both deuterium and tritium. Further, the pure tritium experiments performed required T NBI for high isotopic purity and reduced 14 MeV neutron yield. The use of NBI in tritium presents further challenges compared to standard NBI operation. The experience of preparing, commissioning and operating NBI across the 2021 and 2023 JET D–T experiments are explored in detail in this paper.

中性粒子ビーム入射(NBI)は、トカマクプラズマにおける柔軟な補助加熱手法であり、JET(Joint European Torus)装置でのトリチウムおよび重水素–トリチウム混合実験キャンペーン2において必要とされる様々なプラズマ配位に効率的に結合することができる。高い核融合収量とアルファ粒子研究には高いNBI出力が必要であり、またプラズマコアへの重水素–トリチウム(D–T)混合燃料供給を提供するためには、JET NBIシステムを重水素とトリチウムの両方で運転することが必要であった。さらに、実施された純粋なトリチウム実験では、高い同位体純度と14 MeV中性子収量の低減のためにT NBIが必要であった。トリチウムでのNBIの使用は、標準的なNBI運転と比較してさらなる課題を呈する。2021年および2023年のJET D–T実験におけるNBIの準備、試運転、運転の経験が本論文で詳しく調査される。

This paper discusses the use of neutral beam injection (NBI) for heating and fueling the plasma in the Joint European Torus (JET) device during its Tritium and mixed Deuterium-Tritium Experimental campaigns. NBI was crucial for achieving high fusion yields, studying alpha particles, and providing mixed fuel in the plasma core. The paper explores the challenges of operating NBI in tritium and the experience of preparing, commissioning, and running NBI across the 2021 and 2023 JET D-T experiments.
