Bruker’s GAIA Microscope Set to Ship for Ultra-Cold Quantum Imaging
Bruker is set to ship its first scanning transmission electron microscope (STEM) capable of stable operation near absolute zero to three global labs by early 2027. Dubbed GAIA, the instrument uses liquid helium to cool samples to approximately 7 kelvin for over 30 hours, enabling atomic-resolution imaging of quantum materials. This breakthrough addresses decades-long challenges in cryogenic microscopy, where previous liquid helium attachments suffered from rapid evaporation and vibration-induced blurring. By integrating cooling directly into the microscope and adding aberration correction and a monochromator, GAIA allows researchers to observe material properties at ultra-low temperatures without the instability that previously limited data collection.
