论文摘要
Mosarix是索邦大学的三个研究小组之间的合作项目，该项目可在高效率和良好分辨率的大型设施上构建X射线光谱仪（2-5 KEV）。计划了X射线光谱和一致性实验。已经测试了具有带有von Hamos几何形状的单个HADP晶体的原型（分辨率和效率）。已经实现了快速的时间和位置检测器（专利和出版物）。我们计划使用TimePix3或CCD摄像头在氦气大气下使用8个HADP（或4）晶体建造光谱仪。 Mosarix是具有高效率的X射线域（2-5 KEV）中X射线光谱仪的一个项目，可以使用同步加速器辐射，XFEL，XFEL，未来的安装Spiral2/Ganil或Cryring/Fair进行X射线发射和巧合（或协方差映射）实验。它涉及LCPMR的2组（Francis Penent和Marc Simon），在INSP（Dominique Vernhet）的一组。巧合/协方差测量将在X射线光子和离子或电子之间。这将是与能量分辨光子这样的巧合。光谱仪将是便携式的，并将带到不同的大型设施。 Mosarix是一种针对2-5 KEV光子能量范围优化的多晶体HAPG VON HAMOS光谱仪。它的解决功率E/DE为4000。它将配备快速的时间和位置敏感检测系统，允许执行巧合或与CCD摄像头。 I.科学案例和一些可能的实验X射线源的加速发展，因为3 Rd代同步激素（以及最近的升级）或自由电子激光器为通过光电和螺旋体光谱，电子离子偶然技术和X射线发射提供了新的机会来研究新现象。但是，一些高科学利益的过程仍然很难衡量。其中一些需要以高效率，高分辨率甚至有时以巧合模式测量光子。这是Mosarix开发的目的。例如，我们提议重新审视谐振增强的X射线多电离（REXMI）1，并显着改善光子的检测，即不仅以高效率和高分辨率测量光子，而且与离子或电子一致。这将允许访问所涉及的中间状态，并获得多个电离过程动态的更清晰的图像。 Mosarix还可以用于研究非常低的横截面现象，例如Attosend Electron Dynamics 2和高能量分辨率外光谱（Heros）3,4。 X射线光谱也已被证明是一种非常强大的工具，可以用任何性质，稀释或凝结的5-7进行重离子碰撞的量子动力学。一个
MOSARIX is a collaborative project between three research group in Sorbonne University to build a x-ray spectrometer (2-5 keV) portable to large scale facilities with high efficiency and good resolution. X-ray spectroscopy and coincidences experiment are planned. A prototype with a single HADP crystal with von Hamos geometry has been tested (resolution and efficiency). A fast time and position detector has been realized (patent and publication).We plan to build the spectrometer with 8 HADP (or 4) crystals under Helium atmosphere using a TimePix3 or a CCD camera. MOSARIX is a project of an x-ray spectrometer in the tender x-ray domain (2-5 keV) with high efficiency, allowing performing x-ray emission and coincidences (or covariance mapping) experiments using synchrotron radiation, XFEL, the future installation SPIRAL2/GANIL or CRYRING/FAIR. It involves 2 groups at LCPMR (Francis PENENT and Marc SIMON) and one group at INSP (Dominique VERNHET). The coincidences/covariance measurements will be between x-ray photons and ions or electrons. It would be the first time for such coincidences with energy-resolved photons. The spectrometer will be portable and will be brought to the different large-scale facilities. MOSARIX is a multi-crystal HAPG von Hamos spectrometer optimized for the 2-5 keV photon energy range. Its resolving power E/DE will be 4000. It will be equipped with a fast time and position sensitive detection system, allowing performing coincidences, or with a CCD camera. I. Scientific case and some possible experiments The accelerated development of x-ray sources, as 3 rd generation synchrotrons (and recent upgrades) or free-electron lasers, has opened new opportunities to investigate new phenomena by means of photoelectron and Auger spectroscopy, electron-ion coincidence techniques and x-ray emission. However, several processes of high scientific interests are still hard to measure; some of them require the measurement of photons with high efficiency, high resolution and even sometimes in coincidence mode. This is the purpose of MOSARIX development. As an example, we propose to revisit Resonance-Enhanced X-ray Multiple Ionization (REXMI) 1 with a significant amelioration of the detection of photons, i.e. measuring the photons not only with high efficiency and high resolution but also in coincidence with ions or electrons. This will allow accessing the involved intermediate states and obtaining a clearer image of the dynamic of the multiple ionization process. MOSARIX can also be used for the investigation of very low cross-section phenomena such as attosecond electron dynamics 2 and High-Energy Resolution Off-Resonant Spectroscopy (HEROS) 3,4. X-ray spectroscopy has also proved to be a very powerful tool to investigate quantum dynamics in heavy ions collisions with matter of whatever nature, dilute or condensed 5-7. A
