Resonant magnetic perturbations(RMPs)with high toroidal mode number n are considered for controlling edge-localized modes(ELMs)and divertor heat flux in future ITER H-mode *** this paper,characteristics of divertor heat flux under high-nRMPs(n=3 and 4)in H-mode plasma are investigated using newly upgraded infrared thermography diagnostic in *** splitting strike point(SSP)accompanying with ELM suppression is observed under both RMPs with n=3 and n=4,the SSP in heat flux profile agrees qualitatively with the modeled magnetic *** RMPs suppress ELMs,they increase the stationary heat flux during ELM *** dependence of heat flux on q_(95)during ELM suppression is preliminarily investigated,and further splitting in the original strike point is observed at q 495=during ELM *** terms of ELM pulses,the presence of RMPs shows little influence on transient heat flux distribution.

Lithium Beam Emission Spectroscopy systems in the outer midplane and divertor Langmuir probe arrays embedded in the divertor target plates,are utilized to investigate the scrape-off layer(SOL)blob transition and its relation with divertor detachment on *** blob transition in the near SOL is observed during the density ramp-up *** the plasma density,normalized to the Greenwald density limit,exceeds a threshold of f_(GW)~0.5,the blob size and lifetime increases by 2–3 times,while the blob detection rate decreases by about 2 *** addition,a weak density shoulder is observed in the near SOL region at the same density *** analysis indicates that the divertor detachment is highly correlated with the blob transition,and the density threshold of blob transition is consistent with that of the access to the outer divertor *** potential physical mechanisms are *** results could be useful for the understanding of plasma-wall interaction issues in future devices that will operate under a detached divertor and high density conditions(over the blob transition threshold).

An external resonant magnetic perturbation(RMP)field,which is an effective method to mitigate or suppress the edge localized mode(ELM),has been planned to be applied on the ELM control issue in ITER.A new set of magnetic perturbation coils,named as high m coils,has been developed for the EAST *** magnetic perturbation field of the high m coils is localized in the midplane of the low field side,with the spectral characteristic of high m and wide n,where m and n are the poloidal and toroidal mode numbers,*** high m coils generate a strong localized perturbation *** magnetic topology under the application of high m coils should have either a small or no stochastic *** the combination of the high m coils and the current RMP coils in the EAST,flexible working scenarios of the magnetic perturbation field are available,which is beneficial for ELM control exploration on *** simulations have been carried out to characterize the high m coil system,including the magnetic spectrum and magnetic topology,which shows a great flexibility of magnetic perturbation variation as a tool to investigate the interaction between ELM and external magnetic perturbation.

出版大厦为框架-双核心筒结构体系,采用YJK、ETABS软件对主体结构进行整体计算对比分析。为了满足建筑功能,针对结构的局部转换提出了3种解决方案,并分别通过有限元软件ABAQUS进行转换区3层框架力学性能分析。结果表明:结构在风荷载或地震作用下,主体结构不仅具有很好的抗震性能,而且能满足较好的经济性;局部转换最终采取斜柱转换方案;斜柱转换在竖向荷载的作用下,受力更加均匀,减少了结构节点区域的应力集中现象;在竖向荷载和水平荷载的共同作用下,由于斜柱对框支柱的支撑作用,转换结构的压应力区域由框支柱与水平梁连接处转移到斜柱与框支柱连接处,使整体性更加稳定,为项目结构设计方案选择决策提供参考。
