Liquid helium bath cryostat attoLIQUID3000

The attoLIQUID3000 is a liquid helium based cryostat with a 3He-insert for operation at temperatures from < 350 mK to 300 K. The system is equipped with special low resistance wiring for attocube positioners used in our microscopes, as well as a number of coaxial lines and twisted pairs for customer use. It can be equipped with your choice of superconducting magnet, be it a single solenoid, split coil or 2D/3D vector magnet including suitable magnet power supply. All necessary components needed for a convenient operation are included, such as the renowned attoDAMP anti-vibration cabinet with acoustic damping, a suitable pump for the 1 K pot, a multi-channel temperature controller, a liquid helium level meter and probe, a transfer line and all necessary vacuum fittings. The most outstanding feature of this system is that the 1 K pot is only needed to be pumped during recondensation of the 3He. Afterwards, the unique design allows to turn off the pump at the 1 K pot, which minimizes the residual vibrations considerably. This is what enables the use of sensitive techniques such as scanning probe microscopy in this cryostat at mK temperatures with proven performance (see application section).
