Atomic resolution
Atomic resolution is easily achieved with the MiniCryo STM using a 3.0 micron scanner and an external vibration isolation system. The STM and Cryostat are placed on an isolation platform or suspended from elastic cords.

Operates continuously between 1.5K to 3K
The Mini Cryo STM operates continuously across the temperature range 1.5K to 3K. It can be used with both flow and bath cryostats with sample spaces of 25 mm or larger.

Scanned area up to 5 microns at base temperature
Depending on the scan tube you choose, the scan sizes range from 0.5 x 0.5 microns to 5.0 x 5.0 microns at base temperature.

Demountable interchangeable head
The STM head is demountable from the probe with a plug and socket at the cold end. This is recent modification to the design not shown in the Oxford brochure. It allows the user to easily change the cryo head. ( request drawing 2-039-05100 for details of this arrangement )

Non-magnetic construction
The MiniCryo head is made of titanium which is totally non-magnetic and has an expansion coefficient well matched to the piezo tubes, thus reducing drifts due to temperature variations.

Unique low temperature inertial drive motor
The MiniCryoSTM achieves its remarkable operating range because of the unique design of its piezo inertial drive system. The step size and speed of the motor is variable. A typical step size would be 50 nm providing an overall course approach movement of 5 mm.

25 - 50 mm sample space
The MiniCryo has an OD of 24.8 mm. For larger sample spaces it is supplied on a probe with baffles designed to suit the insert. The unit is supplied ready mounted on an insertion rod to suit your cryostat. The samples are mounted to a sample holder either by clamping or under clips as shown here or by direct bonding.

Compatible with Oxford cryostat and magnet systems
The MiniCryo can be supplied fully integrated an Oxford Instruments cryogenic and superconducting magnet systems.

• CF1200 continuous flow cryostat for fast cool down and excellent cryogen efficiency in short term experiments.
• Optistat Cryostats for optical access,
• Variox bath cryostats for longer run times.
• Teslatron superconducting magnet systems
• Maglab System 2000 magnetic measurement systems.

Suitable for BEEM
Ballistic Electron Emission spectroscopy (BEEM) is a technique which combines the spatial resolution of STM with the ability to probe the local electronic structure.
