[Spectroscopic methodology for the measurement of tokamak plasma].

The states and the distributions of the plasma in the tokamak can be obtained by measuring the spectrum. Since there are many different objects to be measured, many different apparatuses are used to get a better result. Some methods for the measurement are listed in this article. Also the measuring range of each method and some results are listed. On the other hand, a new method was developed according to the conditions of the lab.
