计划将JT-60改造为全超导线圈托卡马克（JT-60 SC），为有吸引力的DEMO反应堆奠定科学和技术基础。JT-60 SC偏滤器的几何设计是为了获得足够的排气能力，以获得高的等离子体压力和II型ELM。为提高靶板的防脱能力，垂直靶板上加装了挡板。cm的SOL通量表面上的外部中平面可以被引导。低温板安装在专用圆顶和外偏滤器下方，以便对内偏滤器支腿和外偏滤器支腿进行单独的压力控制，这对于分离控制很重要。SOLDOR/NEUT 2D数值模拟的初步结果表明，抽气速度的影响因素主要有：六十？m3？s-1，在边缘密度为3.2？1019年？m-3和SOL功率流的qi = qe = 6？MW.
JT-60 is planned to be modified to a fully superconducting coil tokamak (JT-60SC) to establish scientific and technological bases for an attractive DEMO reactor. A divertor geometry for JT-60SC is designed to achieve enough exhaust capability for high triangularity configuration, which is essential to obtain high plasma pressure and type II ELMs. For the improvement of detachment control capability, vertical targets are applied with baffle plates into which 3?cm SOL flux surface on the outer midplane can be led. Cryopanels are installed under both a private dome and an outer divertor to allow separated pressure control for inner and outer divertor legs, which is important for the detachment control. The preliminary results of the numerical simulation with SOLDOR/NEUT2D code show that the pumping speed of ?60?m3?s-1 at an outer pumping slot would be enough to control the detachment at the outer divertor without an X-point MARFE under the condition of the edge density of 3.2?1019?m-3 and the SOL power flow of qi = qe = 6?MW.
