摘要
高能光子探测为研究中高能重离子碰撞的许多重要问题如核物质性质、韧致辐射、阈下和阈上中性介子产生等提供了机遇.简要回顾了近几年国外开展的中能与相对论重离子碰撞高能光子实验概况,并简要介绍了欧洲合作研制的高能光子探测器TAPS的基本构造.另外,用GEANT程序模拟计算了50—1000MeV光子在TAPS标准8×8阵列中的能量响应.
The Measurement of energetic photon produced in intermediate energy and relativistic energy heavy ion collisions provides opportunities for investigating many interesting and sophisticated problems such as properties of nuclear matter under extreme condition, bremsstrahlung, neutral meson production both below and above the production threshold in free nucleonnucleon collision. The related experiments performed at GANIL and GSI as well as the structure of the popular used detector two/three arm photon spectrometer (TAPS) for energetic photon are briefly reviewed. The energy response of the standard 8×8 array of TAPS for incedent energies from 50 MeV to 1 GeV is simulated with GEANT code.
