Liquid helium bath cryostat attoLIQUID1000

attocube's 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. All of attocube's 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. The attoLIQUID1000 provides a base temperature of 4.2 K which can be further reduced down to 2 K by pumping on the Helium reservoir (optional). Superconducting solenoids (up to 15 T), split coils and vector magnets are available as upgrade options. The magnet can be used in driven or in persistent mode. The system includes all necessary components needed for the operation such as the renowned attoDAMP anti-vibration cabinet with acoustic damping, dual channel temperature controller, liquid helium level meter and probe, transfer line and all necessary vacuum fittings.
