Description

Innovation in research is driven by inventive method development. Our aim is to continue in this spirit by
developing a toolkit which will enable high throughput, high precision scanning and multidimensional
experiments on existing transmission electron microscopes (TEMs) for materials and life science research
across Sweden and around the world. We identify three main challenges in electron microscopy: 1) precise
movement and rotation of the specimen; 2) accurate and customisable electron beam scanning; and 3)
selective acquisition of desirable signals. We intend to achieve this in the three work packages that focus on
developing new instrumentation, techniques and methods. WP1 involves the construction of a TEM
specimen holder for fast and precise 3D data collection. WP2 details the implementation of a control unit to
manipulate the electron beam and synchronize the detectors for the acquisition of scanning electron
scattering signals (both Bragg diffraction and diffuse scattering). WP3 realizes a hardware-based solution to
acquire momentum-resolved scanning transmission electron microscopy-electron energy loss spectroscopy
(STEM-EELS). Our innovative architecture will add extra capability to TEMs in terms of imaging,
diffraction and spectroscopy in a cost-effective way. It will also provide customizability through a flexible
framework connecting a wide range of modern and future novel experimental devices.
