چکیده انگلیسی
KSTAR has reached a plasma current up to 630Â kA, plasma duration up to 12Â s, and has achieved high confinement mode (H-mode) in 2011 campaign. The heat flux of PFC tile was estimated from the temperature increase of PFC since 2010. The heat flux of PFC tiles increases significantly with higher plasma current and longer pulse duration. The time-averaged heat flux of shots in 2010 campaign (with 3Â s pulse durations and Ip of 611Â kA) is 0.01Â MW/m2 while that in 2011 campaign (with 12Â s pulse duration and Ip of 630Â kA) is about 0.02Â MW/m2. The heat flux at divertor is 1.4-2 times higher than that at inboard limiter or passive stabilizer. With the cryopump operation, the heat flux at the central divertor is higher than that without cryopump. The heat flux at divertor is proportional to, of course, the duration of H-mode. Furthermore, a software tool, which visualizes the 2D temperature distribution of PFC tile and estimates the heat flux in real time, is developed.
