摘要：Very low Beta superconducting spoke cavity is one of the key challenges for the China-ADS project. In this paper, a new structure of 3βλ/2 spoke cavity is first studied in detail. Its RF and mechanical properties are simulated using CST-MWS and ANSYS, and compared with the traditional βλ/2 spoke structure.

摘要：In this paper, we find the information loss for QCD matter in AdS black holes at LHC by extending the Gottesman and Preski11 methode to AdS black holes. We calculate the information transformation from the collapsing matter to the state of outgoing Hawking radiation for both quarks and gluons. It is noticed that for finite values of quark and gluon energies, information from all emission processes experiences some degrees of loss. Possible explanation for this feature will be presented in this paper.

摘要：12024年10月11日至2025年2月9日,巴黎现代艺术博物馆举办“核子时代”大展,展出上百位东西方知名艺术家作品,通过艺术家想象中的核子世界重温20世纪现代史。20世纪被誉为核子时代。从世纪初原子构成理论和技术的发展、1945年毁灭性的原子弹事件、20世纪下半叶的几次重大核事故,到现代核能的应用,核技术的发展改变着人类的生存和生活,也刺激着艺术家们对科技、物质、事件、政治话语的想象和再创作。

摘要：We give a brief introduction to the AdS/CFT correspondence and its application to QCD physics,especiallyits application in the study of quark-gluon-plasma (QGP)formed in the relativistic heavy ion collision (RHIC).Thisreview is based on the talks given in several schools and programs for the phenomenologists working on nuclear physicsand particle physics.

摘要：航天器在轨服役期间长期处于复杂恶劣的空间辐射环境,以GaAs为代表的III-V族化合物太阳能电池因具备高光电转换效率和抗辐照能力而被广泛应用于航天领域。采用有限元法,基于计算机辅助设计技术(TCAD)对GaAs太阳能电池的空间辐照损伤效应进行了研究。以AM0光谱辐照下的GaAs太阳能电池电学参数为依据,建立了单结太阳能电池结构模型和辐照损伤模型,获得了在不同电子辐照条件下电池的伏安特性曲线,结合已有实验结果验证了本文模拟结果,分析了空间环境辐照下GaAs太阳能电池电学性能退化规律。结果表明,辐照损伤缺陷使得少数载流子扩散长度减小,降低了光生载流子的收集效率,在一定电子能量下,太阳能电池电学性能的退化幅度随辐照注量水平的提高而增大。

摘要：It is generally believed that young, rapidly rotating pulsars are important sites of particle acceleration, in which protons can be accelerated to relativistic energy above the polar cap region if the magnetic moment is antiparallel to the spin axis （μ·Ω 〈 0）. To obtain diffuse neutrinos and gamma-rays at TeV that originate in our Galaxy, we use the Monte Carlo method to generate a sample of young pulsars with ages less than 106 yr in our galaxy; the neutrinos and high-energy gamma-rays can be produced through a photomeson process with the interaction of energetic protons and soft X-ray photons （p ＋γ→△＋→n＋π＋/p＋π0） for a single pulsar, and these X-ray photons come from the surface of the neutron star. The results suggest that the flux of diffuse neutrinos at TeV energies is lower than the background flux, indicating they are difficult to detect using current neutrino telescopes.
