LOW
TEMPERATURE PHYSICS MEASUREMENT SYSTEMS.
:.........................................................................................
Experience your new workhorse designed for cutting edge research
in the fields of nanotechnology, semiconductor research, and
scanning
probe microscopy. attocube systems presents
its product line of low temperature physics measurement systems.
Perform your
experiments time-efficiently, resulting in your company‘s
future nanoscale products, or set benchmarks in your field of
research. Get
maximum mechanical stability with a liquid helium LTSYS or
cut operational
costs by choosing one of our cryogen-free, low temperature
systems.

With these novel ultra-modular and flexible systems, a variety
of scanning probe microscopy (SPM) applications can be adressed.
In addition, a probe
station with up to four probes can be implemented, operating
at temperatures as low as 300 mK.
All these tasks are covered by one single system. This enormous
number of applications is realized by a modular basic
system
in combination with flexible, high-end control electronics, designed
to support your individual research task. A variety of microscopy
inserts is available for this system, all tailored to your individual
application. These inserts
can easily be adapted to suit any of your future needs.
For details on the different microscopy and probe station
inserts, please refer to the ‘nanoSCOPY‘ and ‘nanoTOOLING‘ sections.

pulse tube cooler system optimized for
optical microscopy
The lastest member of the LTSys product line is
the new pulse tube cooler system optimized for optical microscopy.
An integrated
novel
anti-vibration
system facilitates highly sensitive measurements in a cryogen-free
environment. Together with the custom-made radiation shield,
the outer vacuum case and an exchangable optical window
the easy integration with existing optical setups is enabled.
An additonal benfit is that this compact table-top system
suitable
for any optical table.

ultra-stable low temperature physics measurement
systems
The basic LTSYS-He4 systems are based on
a liquid Helium bath cryostat and optimized for highest
stability of your measurements. Options as a variable
temperature insert (VTI), a He3 insert, or a dilution
refrigerator unit, enable to cover a large temperature
range down to the mK regime.
Superconducting magnets up to 15 T are compatible with the system. The compatible
microscopy inserts range from Confocal Microscopy (CFM) and Scanning Nearfield
Optical Microscopy (SNOM) to Atomic Force Microscopy (AFM) and related techniques
(Magnetic Force Microscopy (MFM) and Electric Force Microscopy (EFM), as well
as Scanning Tunneling Microscopy (STM) for measurements with atomic resolution.
Furthermore, probe station modules for cryogenic probing of your NEMS/MEMS
samples are available.

cryogen-free low temperature physics measurement
systems
This cooling system includes a cryogen-free closed-cycle
cryostat for applications where liquid Helium is not
available or desired. Expensive running costs and security
issues can be avoided. An optional Adiabatic Demagnetization
Refrigerator (ADR), or dilution refrigerator unit enables
ultra-low temperature setups. The
automation level allows for ‘set and forget‘ operation
for non-expert users. For these systems, a variety of
Confocal Microscopy (CFM) inserts, the Atomic Force Microscopy
(AFM) insert with MFM and EFM functionality,
as well as the probe station inserts are available.
