Sample Environment - Cryogenic Vacuum

Cryogenic vacuum is obtained in a cryo-cooled volume after reaching the condensing point of the used exchange gas or left over gas particles. Values below 10-15 mbar or even lower can be reached - depending on the specific environmental conditions.

High Magnetic Field

Magnetic field can be generated by different means. From permanent magnets to dedicated pulsed hybrid magnets. In order to maximize the available magnetic field strength and ease of use, attocube uses specially designed superconducting magnets in all cryostats. Since the actual magnetic field strongly depends on the specific geometry, please contact our sales representative for the available options.

Temperature Stability

The temperature stability of a cryostat is specified at 1 K above base temperature with active temperature control. It is defined as the maximum deviation from the temperature setpoint in a 10 minute period. Its actual value can be influenced by the chosen microscope or setup.

Sample Space

Sample space of a cryostat is the space designed to hold the experimental setup without affecting its cooling performance. A larger sample space is desired because it allows more complex measurements and hence makes later upgrades possible.
