attoLIQUID2000
liquid helium based cryostats for variable temperature operation
attocube’s attoLIQUID2000 cryogenic system is based on highly efficient
liquid helium bath cryostats with 50 l cryogenic liquid reservoir, but
also includes a variable temperature insert (VTI) for convenient
temperature control in the range between 1.8 K and 300 K. The system
includes all necessary components needed for the operation such as the
renowned attoDAMP anti-vibration cabinet with acoustic damping, a
suitable rotary pump for the VTI, a dual channel temperature controller,
a liquid helium level meter and probe, a transfer line and all necessary
vacuum fittings.
The system can be equipped with your choice of super-conducting
magnet, be it a single solenoid (up to 15 T), split coils or 2D/3D vector
magnets, including a suitable magnet power supply and the supercon-
ducting leads. The magnet can be used in driven or in persistent mode.
PRODUCT KEY FEATURES
• liquid 4He bath cryostat with 50 l liquid helium
reservoir and variable temperature insert
• temperature range: 1.8 .. 300 K
• capillary heater close to the needle valve to avoid
accidental blockage
• compatible with superconducting magnets up to 15T
BENEFITS
• conduct scanning probe microscopy measurements at
any temperature between 1.8 K and 300 K
• minimized helium consumption compared to directly
pumping the liquid helium reservoir
• minimized mechanical vibrations
