Description

A monochromator is described which is capable of high resolution (resolving power above 50 000) in the near vacuum ultraviolet spectral region. The instrument is equipped with a vibrating mirror before the exit slit, in order to scan the spectral line under study several times during one Tokamak discharge. Examples of ion temperature measurements in the plasma periphery by using impurity lines are given. (author)
