内容記述 | A regression approach has been adopted to acquire a quantitative guidance for updating the total neutron emission rate (Sn) in the Large Helical Device (LHD) with employing the externally controllable parameters such as heating power and plasma density. A deduced regression expression is worthwhile to understand for the contribution of an individual parameter during high Sn discharges, and then to be exploited in the experiment planning to update the record Sn value in LHD in the coming campaigns. It was found that Sn in high Sn discharges in LHD is expressed as Sn = 1014.25 × ne_avg0.52 × PN-NB0.69 × PP-NB0.37, where ne_avg, PN-NB, and PP-NB represent the line-averaged electron density [1019 m−3] and the injection power of negative and positive ions based neutral beam injection [MW], respectively. This expression shows that, among three parameters, PN-NB is essential for achieving high Sn in this employed high Sn discharge database. | |||||
