Abstract

Fusion energy heralds the potential of a transformative era, offering a significant solution to global challenges such as climate change, ozone depletion and environmental pollution. Despite its promising prospects, the commercialization of fusion faces several challenges, including high temperature, pressure, plasma stability, fuel supply, costs, etc. It is important to effectively analyze material behavior under plasma conditions, especially in environments where fusion reactions produce high-energy particles such as neutrons. This study investigates the angle-dependent neutron production mechanisms of proton-induced reactions involving the isotopes ⁹⁰Zr, ⁹¹Zr and ¹¹⁵In, which are widely used in fusion reactor materials. Using the Monte Carlo codes PHITS 3.32 and FLUKA, as well as the TALYS 1.96 code, double differential cross-section calculations for neutron emission were performed considering various angles. The research contributes to a broader understanding of fusion processes by providing insights into the behavior of these isotopes under proton-induced reactions.

关于 90Zr、91Zr 和 115In 同位素中质子诱导反应的中子发射的研究。

核聚变能源预示着一个变革时代的到来，为解决气候变化、臭氧消耗和环境污染等全球挑战提供了重要的解决方案。尽管核聚变前景广阔，但其商业化仍面临一些挑战，包括高温、高压、等离子体稳定性、燃料供应、成本等。有效分析等离子体条件下的材料行为非常重要，尤其是在聚变反应产生中子等高能粒子的环境中。本研究调查了涉及同位素 90Zr、91Zr 和 115In 的质子诱导反应中与角度相关的中子产生机制，这些同位素被广泛应用于聚变反应堆材料中。利用蒙特卡洛代码 PHITS 3.32 和 FLUKA 以及 TALYS 1.96 代码，对中子发射进行了考虑不同角度的双差分截面计算。这项研究有助于深入了解这些同位素在质子诱导反应下的行为，从而加深对核聚变过程的理解。

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.
