The Laplace Project

Ferrovac, in collaboration with leading atom probe scientists, introduced a revolutionary cryogenic UHV transfer system using a customized suitcase and fast-docking station. This innovation secures fragile specimens against damage and contamination, streamlines workflows, and unlocks new possibilities for studying fluid inclusions, hydrogen embrittlement, battery materials, biomolecules, and polymers.

Important Achievements in Laplace Project:

• First demonstration of full cryogenic UHV transfer protocols enabling contamination-free handling of highly sensitive samples (e.g., magnesium, water/ice).
• Suppression of surface oxidation on reactive metals (magnesium) by using cryogenically cooled plasma FIB preparation combined with Ferrovac’s UHV carry transfer suitcase.
• Successful preparation and transfer of frozen water/ice samples without significant melting or sublimation — opening pathways for analysis of liquids and soft materials.
• N₂ glovebox integration proved effective in preventing frost or ice condensation during handling, crucial for hydrogen/deuterium charging experiments.
• Seamless connectivity between multiple platforms (atom probes, SEM/FIB, glovebox) through modular UHVCTS docking, enabling true correlative workflows.
• Enhanced reliability of hydrogen/deuterium mapping in steels and alloys through cold-chain transfer protocols.
