Development of a Novel Liquid Helium Sample Holder for TEM

Since 2017 the team of condenZero, a spin-off company from the University of Zurich, Switzerland (founded in 2019), has been developing new design principles for liquid helium cryostats. Initially created for x-ray diffraction experiments in pulsed magnetic fields, condenZero adapts the miniaturizable cryostat design for TEM sample holder applications. The main goal of the design is to provide a stable base temperature (<10K) over long time periods, enabling new experimental possibilities for TEM research. In this talk, we outline a brief history of condenZero, current challenges, related engineering projects and future milestones for the further development of our next-generation cryo-TEM sample holders.
