Liquid helium bath cryostat - attoLIQUID1000
attocubes attoLIQUID1000 cryogenic system is based on highly efficient liquid Helium bath cryostats with 50 l cryogenic liquid reservoir. As with the whole attoLIQUID family, the attoLIQUID1000 has been optimized for highest stability, enabling experiments such as ultra high resolution imaging and/or spectroscopy using scanning tunneling microscopy (STM) or long-term optical investigations of single quantum dots over several weeks. A large variety of microscopy and probe inserts cover a broad spectrum of measurement tasks. Superconducting magnets up to 15 T are available with this system.The attoLIQUID1000 facilitates a base temperature of 4.2 K which can be furthermore reduced down to 1.8 K by pumping on the Helium reservoir. All of attocubes available scanning probe microscopy inserts are compatible with the attoLIQUID1000 and are cooled by a controlled exchange gas atmosphere in thermal equilibrium with the surrounding liquid Helium. Both superconducting solenoids (up to 15 T) and vector magnets are available as upgrade option.
