Abstract

Advances in Cryogenic Radiation Detectors (September 7, 2023). Cryogenic radiation detectors are attractive because of their extremely high energy resolution, typically on the order of eV for X-rays in the keV range. One of their applications is in astrophysics. Recently, the Japan Aerospace Exploration Agency (JAXA) launched the XRISM (X-Ray Imaging and Spectroscopy Mission) satellite in collaboration with NASA and ESA (for more details, see Daniel Clery, “Revolutionary x-ray sensor to probe workings of black holes and supernovae”, Science, 381, 720–721 (2023). https://doi.org/10.1126/science.adk3474). The X-ray telescope is equipped with a high-energy resolution microcalorimeter detector called Resolve, which is expected to reveal more details about exploding stars, the matter orbiting supermassive black holes, and the merging of galaxy clusters. The detectors appear to be useful not only in such astrophysics, but also in X-ray spectrometry. One of the most important research projects is the precise determination of the fundamental X-ray parameters for many L lines in the soft X-ray region. The research team at NIST in Boulder, Colorado, USA has published a number of papers since 2017 (see, for example, J. W. Fowler et al., “A reassessment of the absolute energies of the x-ray L lines of lanthanide metals”, Metrologia 54, 494 (2017). https://doi.org/10.1088/1681-7575/aa722f, “Absolute energies and emission line shapes of the L x-ray transitions of lanthanide metals”, Metrologia 58, 015016 (2021). https://doi.org/10.1088/1681-7575/abd28a, “Energy Calibration of Nonlinear Microcalorimeters with Uncertainty Estimates from Gaussian Process Regression”, Journal of Low Temperature Physics 209, 1047–1054 (2022). https://doi.org/10.1007/s10909-022-02740-w, “The potential of microcalorimeter X-ray spectrometers for measurement of relative fluorescence-line intensities”, Radiation Physics and Chemistry, 202, 110,487 (2023). https://doi.org/10.1016/j.radphyschem.2022.110487).

低温辐射探测器的进展(2023年9月7日)。低温辐射探测器因其极高的能量分辨率而具有吸引力，通常在keV范围内的x射线的eV数量级上。它们的一个应用是天体物理学。最近，日本宇宙航空研究开发机构(JAXA)与美国宇航局和欧空局合作发射了XRISM (x射线成像和光谱任务)卫星(更多细节，见Daniel cleery，“革命性的x射线传感器探测黑洞和超新星的工作原理”，Science, 381, 720-721(2023)。https://doi.org/10.1126/science.adk3474)。x射线望远镜配备了一个名为Resolve的高能分辨率微热量计探测器，有望揭示有关爆炸恒星、围绕超大质量黑洞运行的物质以及星系团合并的更多细节。这些探测器似乎不仅在天体物理学中很有用，而且在x射线光谱分析中也很有用。其中最重要的研究项目之一是精确确定软x射线区许多L线的基本x射线参数。自2017年以来，美国科罗拉多州博尔德市NIST的研究小组发表了许多论文(例如，参见J. W. Fowler等人，“重新评估镧系金属x射线L线的绝对能量”，Metrologia 54, 494(2017)。https://doi.org/10.1088/1681-7575/aa722f，“镧系金属L - x射线跃迁的绝对能量和发射线形状”，计量学58,015016(2021)。https://doi.org/10.1088/1681-7575/abd28a，“基于高斯过程回归不确定度的非线性微热计能量标定”，低温物理学报，209,1047 - 1054(2022)。https://doi.org/10.1007/s10909-022-02740-w，“微热量计x射线光谱仪测量相对荧光线强度的潜力”，辐射物理与化学，202,110,487(2023)。https://doi.org/10.1016/j.radphyschem.2022.110487)。关于低温辐射探测器及其应用的最新进展，请参见J. Ullom和D. Bennett，“超导x射线和伽马射线能谱过渡边缘传感器的综述”，超导科学技术，28,084003(2015)。https://doi.org/10.1088/0953-2048/28/8/084003和M. Ohkubo，“用于分析仪器的超导体量子和热探测器的进展”，应用物理学报，134,08(2023)。https://doi.org/10.1063/5.0151581

期刊介绍： X-Ray Spectrometry is devoted to the rapid publication of papers dealing with the theory and application of x-ray spectrometry using electron, x-ray photon, proton, γ and γ-x sources. Covering advances in techniques, methods and equipment, this established journal provides the ideal platform for the discussion of more sophisticated X-ray analytical methods. Both wavelength and energy dispersion systems are covered together with a range of data handling methods, from the most simple to very sophisticated software programs. Papers dealing with the application of x-ray spectrometric methods for structural analysis are also featured as well as applications papers covering a wide range of areas such as environmental analysis and monitoring, art and archaelogical studies, mineralogy, forensics, geology, surface science and materials analysis, biomedical and pharmaceutical applications.
