The round-beam operation presents many benefits for scientific experiments regarding synchrotron radiation and the weakening influences of intra-beam scattering in diffraction-limited synchrotron light sources. A round-beam generation method based on the global setting of skew quadrupoles and the application of a non-dominated sorting genetic algorithm was proposed in this study. Two schemes, including large-emittance coupling introduced via betatron coupling and vertical dispersion, were explored in a candidate lattice for an upgrade-proposal of the Shanghai synchrotron radiation facility. Emittance variations with lattice imperfections and their influence on the beam dynamics of beam optic distortions were *** results demonstrated that a precise coupling control ranging from 10 to 100% was achieved under low optical distortion,whereas full-coupling generation and its robustness were achieved by our proposed method by adjusting the skew quadrupole components located in the dispersion-free sections. The Touschek lifetime increased by a factor of 2–2.5.

The CDEX-10 experiment searches for light weakly interacting massive particles, a form of dark matter, at the China Jinping Underground Laboratory, where approximately 10 kg of germanium detectors are arranged in an array and immersed in liquid nitrogen. Herein, we report on the experimental apparatus, detector characterization, and spectrum analysis of one prototype detector. Owing to the higher rise-time resolution of the CDEX-10 prototype detector as compared with CDEX-1 B, we identified the origin of an observed category of extremely fast events. For data analysis of the CDEX-10 prototype detector, we introduced and applied an improved bulk/surface event discrimination method. The results of the new method were compared to those of the CDEX-1 B spectrum. Both sets of results showed good consistency in the 0-12 ke Vee energy range, except for the 8.0 keV K-shell X-ray peak from the external copper.

为分析不同装置高密度电法在第四系潜水含水层圈定工作中的适宜性,本文采用温纳、偶极和施伦贝谢尔3种装置对地下岩土体结构清晰的地区开展高密度电法剖面测量。数据采集、处理和反演解译成果表明,各类高密度电法装置都能够比较有效的识别第四系潜水含水层,但不同装置之间具有较为显著的差异。温纳装置数据采集效率高、纵向分辨率好,并具有较强的抗干扰能力;偶极装置纵向分辨率较好,但深部反演结果具有明显的体积效应,抗干扰能力稍弱,反演拟合误差较大;施伦贝谢尔装置横向分辨率高,但采集数据点数多,耗时长,反演拟合误差最大,抗干扰能力在3种装置中最差。综合对比研究认为,温纳装置具有施工效率高、纵向分辨率高和抗干扰能力强的特点,适宜在第四系潜水含水层圈定中推广使用。
