摘要
介绍了一种具有平面单晶化学气相沉积(sCVD)金刚石传感器的四级光谱仪。它能够测量3mev - 22mev范围内的低能质子。在这项研究中,使用CIVIDEC B14钻石望远镜探测器(Weiss and Griesmayer, 2024)来分析中子与聚乙烯转化器相互作用产生的质子束的能量分布。描述了该光谱仪的背景抑制能力。实验数据与Geant4模拟的13.7(5)MeV高斯能量分布质子束进行了比较。结果表明,实测与仿真结果吻合良好。最后讨论了质子谱仪的性能。
Four-stage diamond spectrometer for low-energy proton identification
A four-stage spectrometer with planar single-crystal chemical vapour deposition (sCVD) diamond sensors is presented. It is capable of measuring low-energy protons in the range of 3 MeV – 22 MeV. In this study, a CIVIDEC B14 Diamond Telescope Detector (Weiss and Griesmayer, 2024) was used to analyse the energy distribution of a proton beam generated by neutron interactions with a polyethylene converter. The background suppression capabilities of the spectrometer are described. The experimental data were compared with Geant4 simulations for a proton beam with a Gaussian energy distribution of 13.7(5) MeV. The comparison shows an excellent agreement between measurement and simulation. The capabilities of the proton spectrometer are finally discussed.
期刊介绍:
Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section.
Theoretical as well as experimental papers are accepted.
