What can Timepix4 performance mean for practical 4D-STEM workflows?

Join Quantum Detectors Ltd. and Thermo Fisher Scientific for a live SelectScience webinar exploring how Timepix4-based detector technology can support advanced electron microscopy and materials characterisation.

Dr. Stefano Vespucci, Staff Scientist at Thermo Fisher Scientific, and Dr. Matus Krajnak, Application Scientist at Quantum Detectors, will discuss recent Timepix4 performance results in a TEM environment and what they mean for practical 4D-STEM acquisition.

The session will cover:
• Frame-based and Data-driven acquisition modes
• Detector performance considerations for 4D-STEM
• Selected application examples
• Future opportunities for event-driven readout and timestamping

For researchers, scientists and engineers working in 4D-STEM, detector technologies and advanced materials characterisation, this is a chance to hear directly from experts working at the front edge of microscopy innovation.

Ptychography is helping researchers extract more information from electron microscopy experiments than ever before.

As datasets continue to grow, the challenge is no longer just reconstruction quality, it's managing the data required to get there.

Merlin T4 combines Timepix4 technology with event-based acquisition to support next-generation 4D-STEM and ptychography workflows.

Advanced reconstruction.

Less data burden.
That'll be Merlin T4.

Visualising Electric Fields with 4D-STEM and STEM-EBIC

Join Dr Eoin Moynihan, University of Warwick, as he explores how complementary 4D-STEM and STEM-EBIC workflows can reveal electric fields, charge carrier behaviour and in-operando semiconductor device performance at the nanoscale.

For the global electron microscopy and semiconductor research community, this webinar offers practical insight into how advanced detector-enabled workflows can help researchers move beyond structural imaging and understand how devices actually behave.

Still collecting frames?
For decades, electron microscopy workflows have relied on frame-based acquisition, generating increasingly large datasets that must be stored, transferred and processed before analysis can begin.

Merlin T4 introduces an alternative approach.

By recording individual electron events rather than continuous image streams, researchers can explore new ways to manage data-intensive workflows and unlock the potential of next-generation electron microscopy applications.

From Frames to Events.
That'll be Merlin T4.

Drowning in detector data?
Modern electron microscopy workflows can generate huge datasets, slowing transfer, storage, processing and analysis.

Merlin T4 offers a different approach.

By recording individual electron events as precise X,Y,T coordinates, Merlin T4 gives researchers the potential to reduce unnecessary data burden while supporting advanced workflows including 4D-STEM, ptychography and diffraction.

Capture events, not terabytes.
That’ll be Merlin T4.

In just under two weeks, the NEMI Workshop at NTNU - Norges teknisk-naturvitenskapelige universitet in Trondheim will bring together the electron microscopy community to explore the transition from traditional TEM to automated, high-throughput “big data” workflows.

We are especially pleased that attendees will get hands-on experience using Merlin detectors as part of advanced workflows spanning:

🔹 3D ED and 4D-STEM
🔹 Automated acquisition with tools such as instamatic and PyJEM
🔹 Data processing using Jana/PETS2, pyxem and HyperSpy

For researchers looking to improve throughput, data quality and workflow automation in electron microscopy, this is a valuable opportunity to see how detector performance supports real scientific applications.

Although the official registration deadline has passed, the organisers have confirmed that late sign-ups are still being accepted.

This year’s workshop will focus on how to collect and analyze (big) data in transmission electron diffraction in a more automatic way than is done traditionally. New possibilities for automation and multidimensional data acquisition, collection routines, better cameras/detectors, and open-source d...

Great to see the Quantum Detectors team in the middle of the discussions at PICO2026.

PICO brings together a focused community of electron microscopy researchers, instrument developers and industry experts working at the cutting edge of aberration-corrected EM, 4D-STEM and detector technology.

This week, Matus Krajnak is presenting our work on Merlin T4 and Timepix4, with a focus on event-based 4D-STEM and what it enables for next-generation experiments.

If you’re at PICO2026, come and find us in Vaals.

We are pleased to see Quantum Detectors MerlinEM featured in a new ACS Nano paper from EPFL researchers studying VO₂ switches. The authors report that SPED data were acquired using a MerlinEM direct detection camera, as part of a workflow combining TEM, SPED, EELS, AFM and electrical analysis.

This matters because it shows MerlinEM supporting the kind of advanced phase mapping and structural analysis needed in publication-grade materials and device research.

When detector technology is trusted in one of the world’s most demanding environments, it says something powerful about the platform behind it.

It is exciting to see CERN Timepix technology playing a role in Artemis II, helping monitor the radiation environment inside the Orion spacecraft on humanity’s return journey towards the Moon.

At Quantum Detectors, that same spirit of innovation underpins Merlin T4, built on the Timepix4 ASIC for advanced event-based and time-resolved electron microscopy.

Space exploration and electron microscopy are very different frontiers, but both depend on detector technology that can perform when the science, environment and expectations are pushing the limits.

Congratulations to CERN Innovation Partnerships and everyone involved in taking this remarkable technology beyond Earth orbit.
