PAGE 66 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 APPLICATION EXAMPLES • inves
