摘要

近二十年来，热释电中子发生器（PNGs）得到了广泛的研究和发展。这些发生器是独一无二的，因为它们是唯一可靠的紧凑型中子源，能够在不需要外部高压电源的情况下产生中子。然而，与其他中子发生器相比，png有一些局限性，包括较低的中子产量和较短的寿命。本文介绍了一种创新的、具有成本效益的方法来提高典型的png的产量，使它们更接近于商业的、电池供电的、适合各种应用的手掌大小的中子发生器的设计。本文通过实验分析探讨了这种方法对热释电加速器电势/电流的影响。此外，在实验中测量了所提出的PNG产生的中子总数，并进行了报道。

An innovative experimental approach for increasing pyroelectric neutron generator yield

Over the past two decades, pyroelectric neutron generators (PNGs) have been extensively researched and developed. These generators are unique as they are the only reliable compact neutron sources capable of producing neutrons without requiring an external high-voltage power supply. However, PNGs have some limitations, including lower neutron production yields and shorter lifespans compared to other neutron generators. This manuscript introduces an innovative and cost-effective approach to enhance the yield of typical PNGs, moving them closer to the design of a commercial, battery-operated, palm-sized neutron generator suitable for various applications. The manuscript investigates the impact of this approach on the electric potential/current of the pyroelectric accelerator through experimental analysis. Additionally, the total number of neutrons produced by the presented PNG is measured during the experiments and is reported.

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.
