attoDRY2100
cryogen free 1.65 K cryostat with optional superconducting magnet
Our range of toploading, dry, low vibration cryostats has been further
extended by the attoDRY2100. It offers a continuous base temperature
of 1.65 K, a automated temperature & magnetic field control from 1.65 K
to 300 K and your choice of superconducting magnet.
The integrated touchscreen allows to conveniently set the desired
field (B) and temperature (T) without even using a PC. More elaborate
measurement schemes such as programmable sweeps of B and T are
easily possible via a USB connection and a LabVIEW interface. The
temperature stability was measured to be better than ±5 mK at 1.5 K
over 10 hours. The toploading design enables quick and easy sample ex-
change, while offering a generous sample space of 49.7 mm in diameter.
The unmatched cooling performance via exchange gas coupling provides
an initial cooldown time of the complete system of around 15-20 hours,
while the turn-around time during sample exchange is around 5-8 hours.
Last but not least, the attoDRY2100 was specifically designed to provide
an ultra-low vibration measurement platform for cryogenic scanning
probe experiments without the need for liquid helium. Due to a propri-
etary 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)*.
