Closed Cycle Cryostat for Spectroscopy Applications

The QMat group operates a liquid Helium-free cryostat for highly sensitive magneto-optical studies. The system is based on the attoDRY1000 model, which is a closed-cycle cryostat specifically designed for low-vibration cryogenic confocal microscopy. The system can be operated within a temperature from 3.8 K to 80 K. A controlled exchange gas atmosphere cools the optional microscope inserts, enabling sensitive measurements. The system is equipped with a superconducting magnet up to 9 T.  Its compatibility with an open optical cavity, that was developed in the QMat group,  provides versatility, enabling seamless integration of various experimental configurations. In free-beam confocal measurements, the lateral vibrations are minimized to approximately 50 nm and vertical vibrations < 1 nm.
