摘要
Results of the first disruption simulation experiment under plasma stream power density of 30-40 MW/cm(2) are presented. POGO and RGT graphite were exposed to perpendicular and inclined incidence of hydrogen plasma stream with energy density up to 1.4 M/cm(2), directed ion energy of 2-3 keV in the presence of magnetic field up to 3.3 T. Optical interferometry and soft X-ray spectroscopy were employed for analysis of target plasma. Contrary to well studied perpendicular plasma impact the inclined plasma incidence results in a drift of target plasma along the sample surface. This restricts the plasma shield effect and increases the erosion rate.
