| 1 | Progress in octahedral spherical hohlraum study显示文摘In this paper,we give a review of our theoretical and experimental progress in octahedral spherical hohlraum study.From our theoretical study,the octahedral spherical hohlraums with 6 Laser Entrance Holes(LEHs)of octahedral symmetry have robust high symmetry during the capsule implosion at hohlraum-to-capsule radius ratio larger than 3.7.In addition,the octahedral spherical hohlraums also have potential superiority on low backscattering without supplementary technology.We studied the laser arrangement and constraints of the octahedral spherical hohlraums,and gave a design on the laser arrangement for ignition octahedral hohlraums.As a result,the injection angle of laser beams of 50°-60°was proposed as the optimum candidate range for the octahedral spherical hohlraums.We proposed a novel octahedral spherical hohlraum with cylindrical LEHs and LEH shields,in order to increase the laser coupling efficiency and improve the capsule symmetry and to mitigate the influence of the wall blowoff on laser transport.We studied on the sensitivity of the octahedral spherical hohlraums to random errors and compared the sensitivity among the octahedral spherical hohlraums,the rugby hohlraums and the cylindrical hohlraums,and the results show that the octahedral spherical hohlraums are robust to these random errors while the cylindrical hohlraums are the most sensitive.Up till to now,we have carried out three experiments on the spherical hohlraum with 2 LEHs on Shenguang(SG)laser facilities,including demonstration of improving laser transport by using the cylindrical LEHs in the spherical hohlraums,spherical hohlraum energetics on the SGIII prototype laser facility,and comparisons of laser plasma instabilities between the spherical hohlraums and the cylindrical hohlraums on the SGIII laser facility. | Ke Lan Jie Liu Zhichao Li Xufei Xie Wenyi Huo Yaohua Chen Guoli Ren Chunyang Zheng Dong Yang Sanwei Li Zhiwen Yang Liang Guo Shu Li Mingyu Zhang Xiaoying Han Chuanlei Zhai Lifei Hou Yukun Li Keli Deng Zheng Yuan Xiayu Zhan Feng Wang Guanghui Yuan Haijun Zhang Bobin Jiang Lizhen Huang Wei Zhang Kai Du Runchang Zhao Ping Li Wei Wang Jingqin Su Xuewei Deng Dongxia Hu Wei Zhou Huaiting Jia Yongkun Ding Wanguo Zheng Xiantu He | 2016 | Matter and Radiation at Extremes2016，1，1： | 2 |
| 2 | Filaments in high-speed counter-streaming plasma interactions driven by high-power laser pulses显示文摘Interactions of two counter-streaming plasmas driven by high power laser pulses are studied on Shenguang II laser facility.Filamentary structures were observed in the interaction region after the electrostatic shockwave decay.Theoretical analysis and observations indicate that the filaments are because of collisionless mechanisms,which are caused by the electromagnetic instability,such as the beam-Weibel instability.Collision experiments were also carried out for comparison and no filaments were generated. | YUAN DaWei LI YuTong SU LuNing LIAO GuoQian YIN ChuanLei ZHU BaoJun ZHANG Jie | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，12： | 2 |

| 4 | Reconstructing avascular necrotic femoral head through a bioactiveβ-TCP system:From design to application显示文摘A variety of techniques have been used for treating avascular necrosis of the femoral head(ANFH),but have frequently failed.In this study,we proposed aβ-TCP system for the treatment of ANFH by boosting revascularization and bone regeneration.The angio-conductive properties and concurrent osteogenesis of the highly interconnected porousβ-TCP scaffold were revealed and quantified through an in vivo model that simulated the ischemic environment of ANFH.Mechanical test and finite element analysis showed that the mechanical loss caused by tissue necrosis and surgery was immediately partially compensated after implantation,and the strength of the operated femoral head was adaptively increased and eventually returned to normal bone,along with continuous material degradation and bone regeneration.For translational application,we further conducted a multi-center open-label clinical trial to assess the efficacy of theβ-TCP system in treating ANFH.Two hundred fourteen patients with 246 hips were enrolled for evaluation,and 82.1%of the operated hips survived at a 42.79-month median follow-up.The imaging results,hip function,and pain scores were dramatically improved compared to preoperative levels.ARCO stage II disease outperformed stage III in terms of clinical effectiveness.Thus,bio-adaptive reconstruction using theβ-TCP system is a promising hip-preserving strategy for the treatment of ANFH. | Yajie Lu Xiantao Chen Xiao Lu Changning Sun Minghui Li Guojing Chen Zuoyao Long Yuan Gao Haoqiang Zhang Mengquan Huang Chuanlei Ji Hongbin Fan Dong Liu Yuewen Hao Hong Wang Leilei Zhang Hongmei Zhang Jianxi Lu Zhen Wang Jing Li | 2023 | Bioactive Materials2023，，10： | 1 |
| 5 | P2 asymmetry of Au's M-band flux and its smoothing effect due to high-Z ablator dopants显示文摘X-ray drive asymmetry is one of the main seeds of low-mode implosion asymmetry that blocks further improvement of the nuclear per-formance of“high-foot”experiments on the National Ignition Facility[Miller et al.,Nucl.Fusion 44,S228(2004)].More particularly,the P2 asymmetry of Au's M-band flux can also severely influence the implosion performance of ignition capsules[Li et al.,Phys.Plasmas 23,072705(2016)].Here we study the smoothing effect of mid-and/or high-Z dopants in ablator on Au's M-band flux asymmetries,by modeling and comparing the implosion processes of a Ge-doped ignition capsule and a Si-doped one driven by X-ray sources with P2 M-band flux asymmetry.As the results,(1)mid-or high-Z dopants absorb hard X-rays(M-band flux)and re-emit isotropically,which helps to smooth the asymmetric M-band flux arriving at the ablation front,therefore reducing the P2 asymmetries of the imploding shell and hot spot;(2)the smoothing effect of Ge-dopant is more remarkable than Si-dopant because its opacity in Au's M-band is higher than the latter's;and(3)placing the doped layer at a larger radius in ablator is more efficient.Applying this effect may not be a main measure to reduce the low-mode implosion asymmetry,but might be of significance in some critical situations such as inertial confinement fusion(ICF)experiments very near the performance cliffs of asymmetric X-ray drives. | Yongsheng Li Chuanlei Zhai Guoli Ren Jianfa Gu Wenyi Huo Xujun Meng Wenhua Ye Ke Lan Weiyan Zhang | 2017 | Matter and Radiation at Extremes2017，2，2： | 1 |

| 8 | A novel hybrid design method of lattice structure based on failure mode显示文摘Adjusting the mechanical properties of lattice structures is important for many modern application fields. In this paper, a new design method for hybrid multi-layer lattice structures was developed to improve the mechanical properties and energy absorption, by altering and suppressing the formation of the shear band. In these hybrids, all unit cells were divided into two parts:(i) diagonal unit cells and(ii) matrix unit cells. Four categories of unit cells were selected to construct the hybrid multi-layer structures. The compressive moduli, ultimate strengths, and energy absorption properties of the laser powder bed fusion(L-PBF)fabricated structures were assessed by experiments and finite element analysis(FEA). The results revealed the great impact of diagonal unit cells on the mechanical properties of the structures. Stronger diagonal unit cells than matrix unit cells led to hybrid structures with enhanced mechanical properties. Compared with a uniform body-centered cubic(BCC) lattice structure, the relative density of the lattice structure consisting of the weakest BCC matrix unit cells and strongest BFVC diagonal unit cells(coupling of BCC, FCC, and VC) exhibited an increase of 20%. The compressive modulus and ultimate strength of this structure rose by more than 200% and 90%, respectively. Two types of structures with specific properties were generated by hybrid design.The first displayed higher modulus, superior strength, and elevated specific energy absorption(SEA) but lower crash load efficiency(CLE). The second illustrated simultaneously higher SEA and elevated CLE. The present results provide a new insight for improving the load-bearing and energy absorption capacities of lattice structures. | Chuanlei Li Junfeng Qi Panding Wang Zeang Zhao Zhe Wang Hongshuai Lei Shengyu Duan | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，9： | 0 |
| 9 | First experimental comparisons of laser-plasma interactions between spherical and cylindrical hohlraums at SGⅢ laser facility显示文摘We present our recent laser-plasmas instability(LPI)comparison experiment at the SGIII laser facility between the spherical and cylindrical hohlraums.Three kinds of filling are considered:vacuum,gas-filling with or without a capsule inside.A spherical hohlraum of 3.6 mm in diameter,and a cylindrical hohlraum of 2.4 mm?4.3 mm are used.The capsule diameter is 0.96 mm.A flat-top laser pulse with 3 ns duration and up to 92.73 kJ energy is used.The experiment has shown that the LPI level in the spherical hohlraum is close to that of the outer beam in the cylindrical hohlraum,while much lower than that of the inner beam.The experiment is further simulated by using our 2-dimensional radiation hydrodynamic code LARED-Integration,and the laser back-scattering fraction and the stimulated Raman scatter(SRS)spectrum are post-processed by the high efficiency code of laser interaction with plasmas HLIP.According to the simulation,the plasma waves are strongly damped and the SRS is mainly developed at the plasma conditions of electron density from 0.08 n_(c) to 0.1 n_(c) and electron temperature from 1.5 keV to 2.0 keV inside the hohlraums.However,obvious differences between the simulation and experiment are found,such as that the SRS back-scattering is underestimated,and the numerical SRS spectrum peaks at a larger wavelength and at a later time than the data.These dif-ferences indicate that the development of a 3D radiation hydrodynamic code,with more accurate physics models,is mandatory for spherical hohlraum study. | Yaohua Chen Zhichao Li Xufei Xie Chunyang Zheng Chuanlei Zhai Liang Hao Dong Yang Wenyi Huo Guoli Ren Jie Liu Xiaoshi Peng Tao Xu Yulong Li Sanwei Li Zhiwen Yang Liang Guo Lifei Hou Yonggang Liu Huiyue Wei Xiangming Liu Weiyi Cha Yukun Li Keli Deng Zheng Yuan Xiayu Zhan Haijun Zhang Baibin Jiang Wei Zhang Kai Du Xuewei Deng Yongkun Ding Xiaofeng Wei Wanguo Zheng Xiaodong Chen Xiantu He Ke Lan | 2017 | Matter and Radiation at Extremes2017，2，2： | 0 |
| 10 | Determination of laser entrance hole size for ignition-scale octahedral spherical hohlraums显示文摘A recently proposed octahedral spherical hohlraum with six laser entrance holes(LEHs)is an attractive concept for an upgraded laser facility aiming at a predictable and reproducible fusion gain with a simple target design.However,with the laser energies available at present,LEH size can be a critical issue.Owing to the uncertainties in simulation results,the LEH size should be determined on the basis of experimental evidence.However,determination of LEH size of an ignition target at a small-scale laser facility poses difficulties.In this paper,we propose to use the prepulse of an ignition pulse to determine the LEH size for ignition-scale hohlraums via LEH closure behavior,and we present convincing evidence from multiple diagnostics at the SGIII facility with ignition-scale hohlraum,laser prepulse,and laser beam size.The LEH closure observed in our experiment is in agreement with data from the National Ignition Facility.The total LEH area of the octahedral hohlraum is found to be very close to that of a cylindrical hohlraum,thus successfully demonstrating the feasibility of the octahedral hohlraum in terms of laser energy,which is crucially important for sizing an ignition-scale octahedrally configured laser system.This work provides a novel way to determine the LEH size of an ignition target at a small-scale laser facility,and it can be applied to other hohlraum configurations for the indirect drive approach. | Yao-Hua Chen Zhichao Li Hui Cao Kaiqiang Pan Sanwei Li Xufei Xie Bo Deng Qiangqiang Wang Zhurong Cao Lifei Hou Xingsen Che Pin Yang Yingjie Li Xiaoan He Tao Xu Yonggang Liu Yulong Li Xiangming Liu Haijun Zhang Wei Zhang Baibin Jiang Jun Xie Wei Zhou Xiaoxia Huang Wen Yi Huo Guoli Ren Kai Li Xudeng Hang Shu Li Chuanlei Zhai Jie Liu Shiyang Zou Yongkun Ding Ke Lan | 2022 | Matter and Radiation at Extremes2022，7，6： | 0 |
| 11 | Exfoliated multi-layered graphene anode with the broadened delithiation voltage plateau below 0.5 V显示文摘The commercial graphite(CG)is the conventional anode material for lithium ion batteries(LIBs)due to its low delithiation voltage plateau(below 0.5 V)and extraordinary durability.Nevertheless,the further promotion of energy density of LIBs is restricted by the limited capacity below 0.5 V of CG.Here,based on the supercritical CO2 exfoliation technique,the production of multi-layered graphene(MLG)is achieved from the pilot scale production line.The great merit of the exfoliated MLG anode is that the voltage plateau below 0.5 V is broadened obviously as compared to those of natural graphite and CG.Additionally,no obvious lithium dendrites are observed for MLG during the lithiation process.The large delithiation capacity under the low voltage plateau of MLG is mainly benefited from the combination of Li intercalation and boundary storage mechanism,which is further confirmed by the density functional theory calculations.The LiFePO4/MLG full cell can afford the satisfactory electrochemical property with respect to the capacity,energy density and ultralong cycling stability(90%capacity retention after 500 cycles at 2 C),significantly better than that of LiFePO4/CG.Besides,this developed technique not only dedicates to producing the high-performance anode for LIBs but also opens a door for the mass production of MLG in the industrial scale. | Xinlong Ma Xinyu Song Yushu Tang Enzuo Liu Chenggen Xu Chuanlei Qi Yun Li Jinsen Gao Yongfeng Li | 2020 | Journal of Energy Chemistry2020，29，10： | 0 |
