ASI VMI online seminar

ASI Velocity Map Imaging Online Seminar

In this seminar, Prof. Thomas Weinacht and Chuan Cheng will discuss a series of velocity map imaging (VMI) experiments which successfully measured the three-dimensional momentum of electrons and ions. The results of these experiments were achieved with the help of ASI TPX3CAM – a hybrid pixel detector which enables researchers to investigate molecular dynamics.

The electrons and ions are produced in strong field ionization and time-resolved photoelectron/photoion spectroscopy experiments. The time resolution of the TPX3CAM allows for direct three dimensional imaging of fragment ion momenta [P_x,P_y,P_z] by measuring [X, Y, TOF] for each ion incident on the microchannel plates + phosphor screen detector. The researchers have recently developed and implemented a new detection method for achieving picosecond time resolution for electron imaging. This new method opens up new possibilities for studying strong field molecular ionization and excited state molecular dynamics.

Ultrafast EM Online Seminar with Direct Single Electron Detector

ASI Ultrafast EM Online Seminar

Ultrafast Electron Microscopy (UEM) facilitates microscopic imaging, diffraction, and spectroscopy at picosecond timescales.

In this online seminar, Prof. Dr. Jonas Weissenrieder [LinkedIn] will talk about the recently constructed UEM set-up at KTH as well as some exciting results achieved using the ASI CheeTah M3 Hybrid Pixel Detector for both diffraction and imaging.

The application of a novel combination of transient grating excitation with Lorentz UEM will be discussed and the professor will share recent, experimental, time-resolved results that provide detailed and real space information of the magnetic precession.


  • Methods to control and detect magnetization dynamics achieving nanometer and picosecond resolution.
  • Promising future applications; the study of spin waves and dynamic behavior in ferrimagnetic and antiferromagnetic systems.
  • Review of a recent study on photo driven structural dynamics in Td-WTe2.
  • Description of the structural response of WTe2 following laser excitation, including excitation of an A1 shear phonon and a photo driven phase transition.
  • The importance of including both short- and long-range optical field interactions in stacking order of 2-dimensional transition metal dichalcogenides.
Online Seminar ASI

ASI Neutron Imaging Online Seminar

Dr. Adrian Losko [LinkedIn] will share that recently developed event-driven detectors are capable of observing and time-stamping spots of light induced by particle interactions on scintillator materials. Reconstructing the Centre-of-Mass of the light emitted can provide a precise location of the interaction. This principle provides a pathway to overcome the blurring introduced by integration of the light emission that often limits the highest possible spatial resolution for imaging techniques using scintillators with standard shutter-based camera systems. Implementing the event-based image reconstruction, we present a new detector concept based on the TPX3CAM, a camera system capable of time-of-flight imaging of light emission with a flexible field-of-view, ad-hoc binning and re-binning of data based on the requirements of the experiment including the possibility of particle discrimination via the analysis of the event shape in space and time. Our most recent results using this system applied to thermal neutron imaging yield an increase by a factor 3 in spatial resolution and an increase by up to a factor of 7.5 in signal-to-noise compared to an integrated response of the light emission from scintillators. The potential applications of this concept are discussed, providing an outlook for the path forward in this development.

  • Event-mode imaging instead of frame-based imaging
  • Achieving excellent spatial resolutions via CoM
  • Particle discrimination via event shape analysis
  • Promising future applications
MD-GAS Event

MD-GAS WG1 & WG2 Conference 2021

Learn about the newest high-performance instrumentation and experimental methods!

From 15th-19th March 2021, MD-GAS COST Action invites experts to share the latest developments of high-performance instrumentation, as well as the gas phase molecular dynamics induced by interactions between molecules/clusters and photons, electrons, or heavy particles, and their applications.

One of ASI’s very own application scientists, Dr. Jingming Long [LinkedIn], will give a detailed technical talk on “Ultrafast and powerful time-stamping camera for investigating molecular dynamics”. This informational session will benefit researchers interested in imaging electrons/ions more efficiently in the study of molecular dynamics.
