Managing 4D-STEM data with smarter acquisition

Managing 4D-STEM data Quantum Detectors webinar

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.

In this SelectScience® webinar, Arno Annys will demonstrate how event-driven electron detection can provide a more efficient representation of electron signals and help streamline the workflow from experiment to scientific insight.

Using application-based examples, the session 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.
