Measurement of the high energyγ-rays from heavy ion reactions usingČerenkov detector

引用

Nuclear Science and Techniques 2024年第2期35卷 123-130页

作者： Da-Wei si Yan Zhou Sheng Xiao Zhi Qin Dong Guo Yu-Hao Qin Yi-Jie wang Bo-yuan Zhang Bai-Ting Tian Zhi-Gang Xiao Department of Physics Tsinghua UniversityBeijing 100084China

The energetic bremsstrahlung photons up to 100 MeV produced in heavy ion collisions can be used as a sensitive probe for short-range correlation in atomic nuclei. The energy of the γ-rays can be measured by collecting the Čerenkov light in the medium induced by the fast electrons generated in the Compton scattering or electromagnetic shower of the incident γray. Two types of detectors based on pure water and lead glass as sensitive materials were designed for this purpose. The γresponse and optical photon propagation in the detectors were simulated based on electromagnetic and optical processes in Geant4. The inherent energy resolutions of 0.022(4) + 0.51(2)∕E^(1/2)_(γ) for water and 0.0026(3) + 0.446(3)∕E^(1/2)_(γ) for lead glass were obtained. The geometry sizes of the lead glass and water were optimized to 30 cm × 30 cm × 30 cm and 60 cm × 60 cm ×120 cm, respectively, to detect high-energy γ-rays at 160 MeV. The Hough transform method was applied to reconstruct the direction of the incident γ-rays, providing the ability to experimentally distinguish the high-energy γ-rays produced in the reactions on the target from random background cosmic-ray muons.

围绕马克思在《德法年鉴》时期与鲍威尔关于犹太人问题的争论,不仅照鉴了他与青年黑格尔派宗教批判思想的决裂,更从此与黑格尔哲学分道扬镳。青年黑格尔派宗教批判本质上是黑格尔理性国家观的延伸,马克思一方面揭示了政治国家解决宗教问题的无能,另一方面将宗教批判转向具有经济性质的市民社会进而挣脱了黑格尔哲学的桎梏。马克思通过对"异化劳动""分工"以及"商品"等视域的考察,不仅使宗教与国家演变成基础结构所决定的上层建筑,更在政治经济学中以拜物教批判的方式深化了对历史唯物主义的反思。
