attoLIQUID3000 liquid helium based cryostats for variable temperature operation
The attoLIQUID3000 is a liquid helium based cryostat with a 3 He-insert for operation at temperatures from 0.3 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 , e . g . a single solenoid , split coil or 2D / 3D vector magnet including suitable magnet power supply .
The most outstanding feature of this system is that the 1 K pot is only needed to be pumped during recondensation of the 3 He . 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 ).
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 .
