The perfect dry VTI: 9T at 300 K, excellent temperature
stability & field cooling
∆T = 1 mK
Investigating samples at variable temperatures and magnetic fields is a
common task in physics and materials science. Using the attoDRY2100,
a closed-cycle cryostat with superconducting magnet, researchers can
easily access the whole phase space of temperature between 1.65 K and
300 K as well as magnetic field, usually -9 Tesla to +9 Tesla (others on
request) without compromises on performance. The cooldown time of an
insert is about 3 .. 7 hours.

In the measurements shown to the left, the attoDRY2100 with an atto3DR
transport measurement insert was first set to a target sample tempera-
ture of 300 K, and then the magnetic field was ramped up from zero Tesla
all the way to the full 9 Tesla. This took about 40 minutes. During this
process, the sample temperature was stable to within sigma = 23 mK. At
9 T and 300 K, the temperature stability was even better at sigma = 10 mK
over more than 6 hours. Subsequently, the sample was field cooled at 9 T
back down to base temperature, which took about 3.5 hours.

The attoDRY2100 is not only capable of reaching the full magnetic field
even at 300 K sample temperature with an excellent temperature stability
(10 mK), but also features the possibility of field cooling a sample. The
whole temperature and magnetic field control is automated, accessible
via the integrated touchscreen or remotely via LabVIEW or a dll.
