在实验冷却器储存环(CSRe)上设计和建造了一台高性能的飞行时间探测器，用于等时质谱分析。该探测器已成功地用于测量质子滴线附近N-≈-Z-≈-33核素的质量。特别令人感兴趣的是65A的质量。实验最大探测效率为70%，时间分辨率为118±8ps(FWHM)。研究了探测效率和信号平均脉冲高度(APH)与原子序数Z的关系。讨论了APH在Z鉴定中的应用潜力。
A high performance Time-of-Flight detector has been designed and constructed for isochronous mass spectrometry at the experimental Cooler Storage Ring (CSRe). The detector has been successfully used in an experiment to measure the masses of the N≈Z≈33 nuclides near the proton drip-line. Of particular interest is the mass of65As. A maximum detection efficiency of 70% and a time resolution of 118±8ps (FWHM) have been achieved in the experiment. The dependence of detection efficiency and signal average pulse height (APH) on atomic number Z has been studied. The potential of APH for Z identification has been discussed.
