A novel flat-panel transmission X-ray source based on nitrogen-incorporated ultra-nano-crystalline diamond (N-UNCD) field emitters is being developed for medical and industrial X-ray imaging. X-ray generation characteristics of the X-ray tubes were simulated with the MCNPX 2.6.0 Monte Carlo code. The simulation results showed that 0.25–12 μm thick tungsten targets could generate an adequate intensity of Bremsstrahlung X-rays. Generated X-ray output intensities of 1.48×1012 MeV/mA-s of 100 kVp electrons hitting the target were found before collimation.

Applied Radiation and Isotopes

APPLIED RADIATION AND ISOTOPES 为发表关于化学、物理、生物化学、生物学、医学、安全、工程和工业领域的核、辐射和放射性核素技术的发展与和平应用的大量、原创和科学技术论文提供了一个高质量的媒介。地球、行星和环境科学，都包括剂量学。核技术是在最广泛的意义上定义的，欢迎实验和理论论文。它们包括开发和使用 Α 和 Β 粒子、X 射线和 Γ 射线、中子和其他核粒子以及来自所有来源（包括放射性核素、同步加速器源、回旋加速器和反应堆）以及来自自然环境的辐射。旨在发表对国际读者具有重要意义的论文，其中包含大量新颖性和科学影响。编辑保留拒绝不符合这些标准的论文的权利，无论是否有外部审查。涉及辐射处理的论文，即辐射被用来引起材料的生物、化学或物理变化的论文，应该是指向我们的姊妹期刊《辐射物理与化学》。

The journal "Applied Radiation and Isotopes" is dedicated to publishing high-quality original research papers on nuclear technology and its peaceful applications in the fields of chemistry, physics, biochemistry, biology, medicine, safety, engineering, and industry. The journal covers a wide range of areas, including Earth, planetary, and environmental sciences, as well as dosimetry. Nuclear technology is defined in the broadest sense, and both experimental and theoretical submissions are welcome. These studies involve alpha and beta particles, X-rays, gamma rays, neutrons, and other nuclear particles from various sources, including radioactive nuclides, synchrotron sources, cyclotrons, reactors, and radiation from the natural environment. The journal aims to publish papers of significant importance to an international readership, emphasizing novelty and scientific impact. The editors reserve the right to reject papers that do not meet these standards, regardless of external review. Papers involving radiation processing, where radiation is used to induce biological, chemical, or physical changes in materials, should be directed to our sister journal, "Radiation Physics and Chemistry."
