attoDRY 1000 Cryogen-free cryostat with optional superconducting magnets

The attoDRY1000 is a cryogen-free cooling system setting new performance benchmarks. The attoDRY1000 was specifically designed to provide an ultra-low vibration measurement platform for cryogenic scanning probe experiments without the need for liquid helium. The standard closed-cycle system enables vibration-sensitive experiments in a temperature range from 4 K to 300 K. The optionally available microscope inserts are cooled by a controlled exchange gas atmosphere. Superconducting magnets up to 9 T are available as an option. Due to a proprietary design, mechanical vibrations created by the pulse-tube coldhead are decoupled from the measurement platform.and 1 top window. Apochromatic objectives with high numerical aperture (NA=0.81-0.95) can either be integrated into the cryostat, into the vacuum shield, or put in close working distance next to the optical windows from the outside. This ensures extremely low drifts and optimal collection efficiency.
When measured with the attoAFM I, vibration amplitudes of less than 0.15 nm RMS are routinely achieved (bandwidth of 200 Hz, vertical direction). Despite the mechanical decoupling between coldhead and sample platform, the cooling performance ot the attoDRY1000 is simply outstanding. Temperatures as low as 3 K and probe cooldown times as fast as 1 hour make cryogenic scanning probe experiments a delight. For the attoDRY1000, a wide variety of scanning probe microscopy inserts is available, ranging from confocal (CFM) to magnetic force microscopy (MFM), as well as transport measurement inserts (atto3DR).

The dependance on liquid helium continues to involve heavy logistics, high prices and insecure supplies. Consequently, closed-cycle cryostats are becoming more and more popular in all areas involving measurements at variable or low temperatures. With the attoDRY series, attocube provides unique instruments with unmatched and proven low mechanical vibrations, unprecedented low acoustic noise levels, and exceptional temperature stability.
Besides, our systems have been optimized for fast turnaround times and hence enable a maximum number of measurement cycles in a minimum amount of time. Superconducting magnets in the form of single solenoids or vector magnets are available for measurements in high magnetic fields. Last but not least, special emphasis has been put into the ease of use through automation of routine procedures, also contributing to a highly professional user experience.
