attoDRY1000
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.
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).
