用于多维光电子能谱的开源端到端工作流程
An open-source, end-to-end workflow for multidimensional photoemission spectroscopy
摘要：
固态材料的电子能带结构的表征通常使用光电子能谱进行。在短波长光源和电子探测器的最新进展引起多维光电发射光谱，允许并行测量的电子光谱功能，同时在能量，两个动量分量和额外的物理参数与单事件检测能力。以高达每秒数十兆字节的速率对光电子事件流进行有效处理将使材料表征的快速带映射成为可能。我们描述了一个开源的工作流程，允许用户互动与十亿计数单电子事件的光电带映射实验，兼容光束线在$3^{\text{rd}}$和$4^{\text{th}}$代光源和桌面激光为基础的设置。该工作流程提供了端到端的方法，从单事件数据的分布式操作到下游科学任务的结构化格式，以及从存储到材料科学数据库集成。工作流程和处理后的数据都可以存档以供重复使用，为将来的高通量实验提供记录光电发射数据来源和谱系的基础设施。
英文摘要：
Characterization of the electronic band structure of solid state materials is routinely performed using photoemission spectroscopy. Recent advancements in short-wavelength light sources and electron detectors give rise to multidimensional photoemission spectroscopy, allowing parallel measurements of the electron spectral function simultaneously in energy, two momentum components and additional physical parameters with single-event detection capability. Efficient processing of the photoelectron event streams at a rate of up to tens of megabytes per second will enable rapid band mapping for materials characterization. We describe an open-source workflow that allows user interaction with billion-count single-electron events in photoemission band mapping experiments, compatible with beamlines at $3^{\text{rd}}$ and $4^{\text{th}}$ generation light sources and table-top laser-based setups. The workflow offers an end-to-end recipe from distributed operations on single-event data to structured formats for downstream scientific tasks and storage to materials science database integration. Both the workflow and processed data can be archived for reuse, providing the infrastructure for documenting the provenance and lineage of photoemission data for future high-throughput experiments.
