attocube - Model attoLIQUID2000 - Liquid Helium Cryostats
attocube‘s attoLIQUID2000 superconducting magnet 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 superconducting magnet, be it a single solenoid (up to 12 T), split coils or 2D/3D vector magnets, including a suitable magnet power supply and the superconducting leads. The magnet can be used in driven or in persistent mode.
