Quantitative tritium inventory in dust particles from campaigns in the JET tokamak with the carbon wall (2007–2009) and the ITER-like wall (ILW 2011–2012) were determined by the liquid scintillation counter and the full combustion method. A feature of this full combustion method is that dust particles were covered by a tin (Sn) which reached 2100 K during combustion under oxygen flow. The specific tritium inventory for samples from JET with carbon and with metal walls was measured and found to be similar. However, the total tritium inventory in dust particles from the ILW experiment was significantly smaller in comparison to the carbon wall due to the lower amount of dust particles generated in the presence of metal walls.

从JET中的ILW尘埃颗粒中测定残留retained

通过液体闪烁计数器和完全燃烧法确定了JET托卡马克含碳壁(2007–2009)和ITER样壁(ILW 2011–2012)的运动中尘埃粒子中的tri定量存积。这种完全燃烧方法的一个特点是灰尘颗粒被锡(Sn)覆盖,在氧气流下燃烧期间锡达到2100K。测量了JET含碳和金属壁的样品的特定tri存量,发现这些存量是相似的。但是,由于存在金属壁时产生的尘埃颗粒数量较少,因此与碳壁相比,来自ILW实验的尘埃颗粒中的总inventory存量明显较小。
