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.

为了研究稳态等离子体辐照和瞬时热/颗粒载荷面向等离子体材料的协同作用，开发了一种新的等离子枪装置，并将其与线性等离子体设备Nagdis-I合并。为了测量血浆密度，开发了干涉仪测量。通过光谱测量离子温度。用量热计测量脉冲血浆的能量密度。我们还使用具有较高时间分辨率的ISS光合检测器开发了能量密度测量。此外，对血浆脉冲进行了对钨样品的初步辐照测试，并通过扫描电子显微镜通过扫描电子显微镜进行了分析，显示了表面形态的变化。
