Fusion experiments use lithium and boron getters to capture impurities and control the density of fuel species in the plasma. In the TJ-II Stellarator, the addition of a boron-carbon substrate was found to extend the lifetime of the very reactive lithium wall conditioning. However, the synergies between the lithium layer and the underlying boron-carbon, or the effect of a glow discharge cleaning, on oxygen and deuterium gettering are not fully understood. Laboratory experiments were therefore initiated to gain deeper insight on the getter properties of B(C)/Li walls. The coatings were exposed to oxygen gas and plasmas while the capture and release of O ##IMG## [http://ej.iop.org/images/0029-5515/60/10/106001/nfaba72dieqn1.gif] {$_\mathrm{2}$} was followed by mass spectrometry. Without the boron substrate, the maximum oxygen uptake is half the number of lithium atoms in the film for both oxygen gas and oxygen plasma. Conversely, the behaviour of B(C)/Li walls...

硼在锂薄膜性能中的协同作用

聚变实验使用锂和硼吸气剂来捕获杂质并控制等离子体中燃料种类的密度。在TJ-II恒星仪中，发现添加硼碳底物可以延长反应性强的锂壁调节的寿命。然而，锂层和下面的硼碳之间的协同作用或辉光放电清洗对氧气和氘气吸杂的影响尚未完全了解。因此，开始进行实验室实验，以更深入地了解B（C）/ Li壁的吸气性能。在捕获和释放O ## IMG ## [http://ej.iop.org/images/0029-5515/60/10/106001/nfaba72dieqn1.gif]的过程中，将涂层暴露于氧气和等离子体_ \ mathrm {2} $}之后进行质谱分析。没有硼底物 对于氧气和氧气等离子体，最大摄氧量是薄膜中锂原子数量的一半。相反，B（C）/ Li墙的行为...
