attoLIQUID1000
liquid helium based superconducting magnet systems
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 a s 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.
