Abstract

Recent experimental investigations have demonstrated that a substantial amount of H⁻or D⁻ ions can be produced by thermal desorption processes. Based on these new findings, new mini neutron sources can now be developed to produce high-energy neutrons via the d-¹⁰B nuclear reaction. By operating these mini neutron tubes with a high frequency AC high-voltage supply, short pulses of high intensity neutron beams can be generated. The d-¹⁰B neutrons should be suitable for compensated porosity and carbon/oxygen ratio measurements in oil well logging. It is shown that the performance of these new mini neutron tubes can exceed those of the commonly used Am-Be or d-t neutron sources.

最近的实验研究表明，热解吸过程可以产生大量的 H 或 D 离子。基于这些新发现，现在可以开发新的微型中子源，通过 d-10B 核反应产生高能中子。通过使用高频交流高压电源操作这些微型中子管，可以产生高强度中子束的短脉冲。d-10B 中子应适用于油井测井中的补偿孔隙度和碳/氧比测量。研究表明，这些新型微型中子管的性能可以超过常用的 Am-Be 或 d-t 中子源。

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
