CTAMOP paper on diagnostic applications in nuclear fusion reactors

Last updated May 30, 2017 by Andrew Brown

Congratulations to Stefan Spencer, a third year PhD student in CTAMOP, who has recently published his first paper in J.Phys.B:At.Mol.Opt.Phys. alongside Professor Alan Hibbert and Dr Cathy Ramsbottom. The publication entitled “Oscillator Strengths and Transition Probabilities for the WXLV Ion” is of interest in diagnostic applications in nuclear fusion reactors such as the International Thermonuclear Experiment Reactor (ITER). The ITER experiment currently under construction in Cadarache, France is a global effort to build the largest magnetically confined tokamak. It is hoped that this large torus shaped device will bring fusion physicists and engineers one step closer to a commercially viable reactor. The material choice for the plasma facing components in fusion experiments must be determined by competing desirables; on the one hand the material should have a high threshold for melting and sputtering, and low erosion rate under plasma contact. On the other, as a plasma impurity it should not cause excessive radiative energy loss. Therefore tungsten has been chosen as one such wall material. All ionization stages of tungsten are of importance and the radiative data produced in this publication will be applicable to numerous diagnostic applications.
