论文摘要
先进的电子显微镜工作流程需要一个可能位于不同站点的显微镜仪器和计算系统的生态系统,以进行远程转向和自动化实验。当前的工作流程执行涉及用于转向和测量任务的手动操作,这些操作通常是从与显微镜共同分层的控制工作站执行的;因此,他们的操作节奏和有效性是有限的。我们提出了一种基于扫描传输电子显微镜(STEM)和计算系统生态系统的单独数据和控制渠道的方法,与中子和光源仪器不同,目前不存在一般解决方案。我们展示了自动测量转移和远程转向站点网络上的Nion STEM物理仪器。我们提出了本生态系统的虚拟基础架构双(VIT),该双(VIT)用于开发和测试我们的转向软件模块,而无需访问物理仪器基础架构。此外,我们为多个实验室方案开发了一个VIT,该VIT说明了这种方法对通过广阔区域网络连接的生态系统的适用性,用于开发和测试软件模块及其后来的现场部署。
Advanced electron microscopy workflows require an ecosystem of microscope instruments and computing systems possibly located at different sites to conduct remotely steered and automated experiments. Current workflow executions involve manual operations for steering and measurement tasks, which are typically performed from control workstations co-located with microscopes; consequently, their operational tempo and effectiveness are limited. We propose an approach based on separate data and control channels for such an ecosystem of Scanning Transmission Electron Microscopes (STEM) and computing systems, for which no general solutions presently exist, unlike the neutron and light source instruments. We demonstrate automated measurement transfers and remote steering of Nion STEM physical instruments over site networks. We propose a Virtual Infrastructure Twin (VIT) of this ecosystem, which is used to develop and test our steering software modules without requiring access to the physical instrument infrastructure. Additionally, we develop a VIT for a multiple laboratory scenario, which illustrates the applicability of this approach to ecosystems connected over wide-area networks, for the development and testing of software modules and their later field deployment.
