Managing the 4D-STEM Data Explosion: Event-Driven Acquisition, Adaptive Scanning and Real-Time Ptychography
Tuesday, September 8 at 14:00 BST | 15:00 CEST | 09:00 EDT | 06:00 PDT
Modern pixelated detectors can generate tens to hundreds of gigabytes of data during a single 4D-STEM scan, creating practical challenges for acquisition, processing and interpretation.
This webinar will demonstrate how event-driven electron detection can provide a more efficient representation of the electron signal and help streamline the workflow from experiment to scientific insight.
Using application-based examples, Arno Annys will explore how event-driven acquisition, adaptive scanning strategies and real-time ptychographic reconstruction can reduce the 4D-STEM data burden, support low-dose experiments and provide immediate feedback during acquisition.
Attendees will learn how these approaches can make advanced 4D-STEM experiments more scalable, responsive and accessible for routine use.
