To harness the rich solar energy resources in Xinjiang Region of Northwest China,this study tries to address the issue of lack of downward surface shortwave radiation(DSSR)observations and the need to improve the accuracy of satellite retrieval and numerical simulation of DSSR under varied sky and meteorological conditions.(1)A two-layer aerosol model specific to Xinjiang was developed to capture the vertical distributions of aerosols based on multiple data sources including lidar,GPS sounding,ground meteorological observations,and profiles from the ECMWF reanalysis version 5(ERA5)*** results show that the ERA5/PBLH(planetary boundary layer height)and ERA5/ALH(aerosol layer height)could be used to establish the two-layer aerosol model and characterize the vertical distribution of aerosols in Xinjiang Region.(2)Using the Santa Barbara Discrete Atmospheric Radiative Transfer(SBDART)model,a localized inverse model of clear-sky DSSR was *** parameter adjustment and using the optimal combination of input parameters for DSSR simulation together with the two-layer aerosol model,the model-simulated DSSR(DSSRSBD)under clear-sky conditions improved significantly compared to the initial results,with all fitting indices greatly improved.(3)In addition,the study demonstrated that the impact of the two-layer aerosol model on DSSR was more pronounced under dust conditions than clear-sky conditions.(4)Using the localized clear-sky DSSR inversion model and its required parameters,simulations were also conducted to capture the spatiotemporal distribution of DSSR under clear-sky conditions in Xinjiang from 2017 to *** annual average DSSR_(SBD)under clear-sky conditions in Xinjiang during 2017–2019 was 606.78 W m^(-2),while DSSR from CERES(DSSR_(CER))under the same conditions was generally higher(703.95 W m^(-2)).(5)It is found that satellite remote sensing products experienced data loss in high-altitude snow areas,where numerical simulation technology could ser

A prototype RF power source for CSNS/RCS

第一届中国粒子加速器会议

作者： huang weiling SUN Hong ZHAO HaiQi LIU Yu LI YanDong QIAO ZhiGuang LI Xiao ZHANG ChunLin Accelerator Center Institute of High Energy PhysicsChinese Academy of Sciences

A prototype RF power source has been built to supply high RF power to a ferrite-loaded cavity,which is a part of R & D of the Rapid Cycling Synchrotron of China Spallation Neutron Source(CSNS/RCS).A direct fast RF feedback amplifier,a 4:1 impedance transformer and auto tuning grid were locally located to compensate the heavy beam loading of CSNS/*** and commissioning of the RF power source is discussed here,also with some advice on system improvement.

CoNiCrFeMn高熵合金因具高强韧性、耐磨损与抗蚀性、抗高温、耐超低温等优异性能,在深海破冰探测、超音速发动机、空天超声电机等重大应用领域可发挥重要作用。若能了解多晶CoNiCrFeMn高熵合金的微观演化特性,将推动其应用发展。因此,基于经典力学的分子动力学法,对纳米压痕诱导多晶CoNiCrFeMn高熵合金的载荷与压深曲线相对应的微结构动态演化特性进行研究,揭示出多晶CoNiCrFeMn高熵合金受载诱导的位错运动特性。研究表明,多晶CoNiCrFeMn高熵合金步入塑性变形阶段时,会出现无定型非晶化并产生位错堆垛形核,且两者均随压深增加而逐渐增多。此外,因载荷诱导产生的应力集中易导致紧密接触区晶粒内的位错发生滑移,而晶界对位错滑移起阻碍作用。随着压深持续增加,非晶化一旦到达晶界处就不再继续,而是以位错发射形式在相邻晶粒中释放应力,此时晶界成为位错发射源。研究表明:在弹性阶段,当温度低于300 K时,载荷与压深对温度不敏感;而在塑性阶段,随温度升高,载荷大幅下降。另外,温度升高易诱导多晶CoNiCrFeMn高熵合金上表面起伏程度加剧,但紧密接触边缘两侧起伏程度呈现非均匀性。本研究给出了受载响应的多晶CoNiCrFeMn高熵合金内部微结构的动态演变进程,对理解多晶CoNiCrFeMn高熵合金塑性变形机制有着重要的学术参考意义,也对后期设计具有优异力学性能的多晶CoNiCrFeMn高熵合金微结构起到重要的推动作用。

为了利用负氢离子加速器中伴随产生的质子成分,中国散裂中子源(China Spallation Neutron Source,CSNS)在直线加速器末端建设了伴生质子辐照实验平台(associated protons experimental platform,APEP)。为了确定其性能参数,采用散射测量、束斑照相、同位素活化法等实验方法对伴生质子辐照实验平台的主要参数进行了刻度。实验证实,该辐照平台可以提供的质子能量范围为10~80 MeV,束斑分布均匀,束流强度范围为1.2×10^(7)~4.0×10^(9) cm^(-2)·s^(-1)。伴生质子辐照实验平台运行稳定,每年提供超过5000 h的束流时间,可以满足宇航器件可靠性测试、探测器刻度、辐照育种以及材料抗辐照特性测试等多种应用需求。
