Ultrafast electron microscopy at CEMES: on March 8, inauguration of the new joint laboratory between CNRS and Hitachi High Technologies Corporation

Developments around ultrafast electron microscopy at CEMES have seen significant progress over the last year. The promising results obtained on a first prototype of ultrafast Transmission Electron Microscope (UTEM) developed in CEMES motivated the creation in 2018 of a first joint laboratory between CNRS and the Japanese company Hitachi High Technologies Corporation (HHT). The objective of this laboratory called HC-IUMi (Hitachi-CNRS Infrastructure for Ultrafast Microscopy) was to transfer the ultrafast electron source from the old HF2000 microscope which served as the basis for the prototype to an HF3300, a last generation 300 kV Hitachi TEM.

The installation of this microscope in a completely renovated room in 2019 was followed by several important modifications of the instrument to prepare the transfer of the ultrafast electron source. In June 2023, the first laser-driven electron emission has been obtained on the new UTEM. This achievement successfully closed the five years of the first joint laboratory.

Given the success of HC-IUMi, CNRS and HHT decided in 2023 to continue the scientific and technological cooperation in the form of HC-IUMi 2 new joint laboratory. This laboratory aims at going beyond proof-of-principle experiments and demonstrate the full potential of ultrafast electron microscopy on several cutting-edge applications in nano-optics, nano-mechanics, and nanomagnetism.

HC-IUMi 2 will be officially inaugurated on March 8.
