WebJun 4, 1998 · This analysis indicates that bremsstrahlung from the plasma center and impurity radiation from the plasma edge and divertor plasma can each play a significant role in reducing the power to the divertor plates, and identifies many of the factors which determine the relative role of each process. WebAug 16, 2012 · The divertor is deliberately in contact with the plasma and so needs a tougher coating. For this, the plan is to use tungsten, which can withstand the heat in the divertor region—lower than in the bulk of the plasma—but if some does get eroded away, it poisons the plasma pretty badly. kenneth weaver obituary
