condenZero AG is a company for external training assignments for ETH Physics Laboratory Technician (Physiklaborant EFZ) apprentices.


The Swiss Free Electron Laser (SwissFEL) facility is poised to revolutionize our understanding of ultrafast photochemistry, photobiology, and condensed matter dynamics. For x-ray diffraction experiments on quantum matter systems in pulsed magnetic fields (image to the left), no off-the-shelf product could meet the harsh conditions of low temperatures and compact dimensions. Responding to these demands, Dominik Biscette developed a novel cryostat design. By spring 2017, the first prototype was produced, surpassing the desired functionality. This new design achieved a lower base temperature, faster cooling rate, and reduced physical dimensions, outperforming existing cryostats. In 2019, a patent application for the design principle was filed, and the same year saw the founding of condenZero. The company aims to implement this cutting-edge cryostat technology for cryo-TEM sample holders and other scientific instruments.
