一个一维的流体模型,计算修改的密度和温度沿着磁场和平行的电场中存在的局部杂质源,已被实施到ERO代码。研究了杂质源强度对局域等离子体参数的影响以及由此引起的杂质输运和沉积的变化。专门的TEXTOR实验13CH4注入通过屋顶样的测试限制器建模进行比较。高注入速率(大于约4×1018s−1)的模型会导致注入孔附近的光发射模式过于局部化,因此表明模型中低估了电子温度的降低。此外,初步结果表明,可能的修改局部等离子体条件不能显着减少modelled13 C沉积,因此不能解释测得的低13 C沉积效率。
A one-dimensional fluid model, which calculates the modification of density and temperature along the magnetic field and the parallel electrical field in the presence of local impurity sources, has been implemented into the ERO code. The influence of impurity source strength on the local plasma parameters and resulting changes in impurity transport and deposition has been studied. Dedicated TEXTOR experiments of13CH4injection through roof-like test limiters are modelled for comparison. Modelling with high injection rates (larger than about 4×1018s−1) results in too localized light emission pattern near to the injection hole, and therefore indicates an underestimation of the reduction of electron temperature in the model. Besides, the preliminary results indicate that possible modification of local plasma conditions cannot significantly reduce the modelled13C deposition and therefore cannot explain the measured low13C deposition efficiency.
