Atomic processes in fusion research

JT-60, a large tokamak of JAERI with plasma volume of 60 m3, will be in operation in April, 1985. Prior to the plasma operation, the compilation and evaluation of atomic and molecular (A and M) data relevant to plasma diagnostics have been carried out. In this paper, a brief review is given to the present status of mainly the compilation and evaluation of atomic structure and collision data for tokamak plasma diagnostics in JAERI. It is very useful to compile wave length, energy level, oscillator strength and transition probability of highly ionized ions, because of the importance of these ions for the diagnostics of high temperature plasma. During a series of the compilation, a computer program for making Grotrian diagrams proposed by Mori has been developed. The experimental data on atomic collision process mainly related to charge transfer and others relevant to fusion research have been compiled. All the compiled data on atomic structure and collision are now stored in the computer system of JAERI by its own formats. Some of them are available to interested users in the form of magnetic tapes. (Kako, I.)
