| Research Abstract |
To investigate synergistic effects of steady state plasma irradiation and transient heat/particle loads to plasma facing materials, a new plasma gun device was developed and was combined to the linear plasma device NAGDIS-I. To measure the plasma density, an interferometer measurement was developed; the ion temperature was measured spectroscopically.
The energy density of the pulsed plasma was measured with a calorimeter. We also developed the energy density measurement with InGs photo detectors with a high time resolution.
Moreover, a preliminary irradiation test of the plasma pulse to a tungsten sample was conducted, and the surface morphology change was shown with the analysis by a scanning electron microscope.
