Abstract

In preparation for an experiment with a laser-generated intense proton beam at the Laser Fusion Research Center at Mianyang to investigate the 11B(p,α)2α reaction, we performed a measurement at very low proton energy between 140 keV and 172 keV using the high-voltage platform at the Institute of Modern Physics, Lanzhou. The aim of the experiment was to test the ability to use CR-39 track detectors for cross-section measurements and to remeasure the cross-section of this reaction close to the first resonance using the thick target approach. We obtained the cross-section σ = 45.6 ± 12.5 mb near 156 keV. Our result confirms the feasibility of CR-39 type track detector for nuclear reaction measurement also in low-energy regions.

第一共振能量附近11B(p，α)2α反应的截面测量

为了准备在绵阳激光聚变研究中心用激光产生的强质子束研究11B(p，α)2α反应，我们利用兰州现代物理研究所的高压平台在140 - 172 keV的极低质子能量下进行了测量。实验的目的是测试使用CR-39轨道探测器进行截面测量的能力，并使用厚靶方法重新测量该反应靠近第一共振的截面。在156 keV附近得到了截面σ = 45.6±12.5 mb。我们的结果证实了CR-39型径迹探测器用于低能区核反应测量的可行性。

期刊介绍： Laser and Particle Beams is an international journal which deals with basic physics issues of intense laser and particle beams, and the interaction of these beams with matter. Research on pulse power technology associated with beam generation is also of strong interest. Subjects covered include the physics of high energy densities; non-LTE phenomena; hot dense matter and related atomic, plasma and hydrodynamic physics and astrophysics; intense sources of coherent radiation; high current particle accelerators; beam-wave interaction; and pulsed power technology.
