Overview
The Scanner16-z is a high-precision, ultra-compact piezoelectric Z-axis translation stage engineered for extreme experimental environments—specifically low-temperature physics, ultra-high vacuum (UHV) surface science, and high-field magnetism research. Unlike conventional motorized or stepper-driven stages, the Scanner16-z employs monolithic piezoelectric actuation with direct strain coupling, enabling sub-nanometer closed-loop positioning without mechanical backlash or hysteresis-induced drift. Its operational principle relies on inverse piezoelectric effect in custom-engineered PZT stacks integrated within a thermally symmetric, stress-relieved titanium–beryllium copper (Ti/BeCu) frame. This architecture ensures dimensional stability across thermal cycles from 1.4 K to 400 K and mechanical integrity under magnetic fields up to 18 Tesla—making it suitable for integration into dilution refrigerators, He-3 cryostats, and superconducting magnet systems.
Key Features
- Ultra-miniaturized footprint: 16 mm × 16 mm × 6 mm—among the smallest commercially available piezo-driven Z-stages for cryogenic UHV applications.
- Multi-environment compatibility: Validated for operation at base temperatures down to 30 mK (ULT version), vacuum pressures as low as 2×10⁻¹¹ mbar (UHV version), and static magnetic fields up to 18 T.
- Magnetically inert construction: Structural components fabricated exclusively from non-ferromagnetic pure titanium and beryllium copper; zero magnetic susceptibility contribution to experimental perturbation.
- High-resolution motion control: Achieves 0.5 nm open-loop resolution with typical linearity error of ~0.1% and repeatability better than 10 nm—critical for atomic-scale scanning probe microscopy (SPM) and quantum device alignment.
- Thermally optimized electrical interface: Phosphor bronze twisted-pair cabling (20 cm standard length) minimizes thermal load and inductive coupling; hermetic glass-fiber-filled polyetheretherketone (PEEK) and BeCu pin feedthroughs ensure reliable signal transmission under thermal contraction.
- Scalable voltage drive: Rated for up to 75 V at room temperature and 180 V at 4 K—enabling full 30 µm stroke retention across cryogenic regimes without performance degradation.
Sample Compatibility & Compliance
The Scanner16-z meets stringent requirements for integration into regulated and mission-critical instrumentation platforms. Its materials and assembly processes conform to ASTM F519 (stress-corrosion resistance of titanium alloys) and ISO 10993-5 (biocompatibility screening—relevant for ultra-clean chamber handling). While not certified per FDA 21 CFR Part 11, its deterministic motion behavior, traceable calibration data (available upon request), and intrinsic repeatability support GLP/GMP-aligned metrology workflows in academic and national lab settings. The UHV variant complies with ESA ECSS-Q-ST-70-02C outgassing specifications (<1×10⁻¹² Pa·m³/s·cm² total mass loss), and all versions are compatible with bake-out procedures up to 150 °C (non-operational).
Software & Data Management
The Scanner16-z operates via analog voltage input (±10 V or 0–10 V, configurable), enabling seamless integration with third-party motion controllers—including those compliant with NI PXI, Thorlabs Kinesis, or Zurich Instruments HF2LI platforms. Optional digital interface modules (e.g., SPI or LVDS) support synchronization with time-resolved measurements such as pump-probe spectroscopy or qubit readout sequences. All operational parameters—including applied voltage, estimated displacement, and thermal status—are accessible via analog monitoring outputs. No proprietary software is required; users retain full control over trajectory generation, feedback loop configuration, and data logging through existing laboratory automation frameworks.
Applications
- Cryogenic scanning tunneling microscopy (STM) and atomic force microscopy (AFM) coarse/fine approach mechanisms.
- Quantum dot and superconducting qubit die alignment inside dilution refrigerator insert stages.
- In-situ sample height adjustment for angle-resolved photoemission spectroscopy (ARPES) and X-ray standing wave experiments under UHV.
- Active vibration isolation compensation in ultra-stable optical cavities operating below 4 K.
- Sub-micron focusing actuation for fiber-coupled single-photon detectors in quantum communication testbeds.
FAQ
What vacuum levels is the Scanner16-z rated for?
The UHV version is qualified to 2×10⁻¹¹ mbar; the standard HV version is rated to 2×10⁻⁷ mbar.
Can the Scanner16-z be used in a 12-Tesla superconducting magnet?
Yes—it is fully compatible with static magnetic fields up to 18 Tesla due to its non-magnetic Ti/BeCu construction.
Is thermal contraction of the stage compensated in position feedback?
No built-in thermal compensation is implemented; users must apply empirical correction based on calibrated displacement vs. temperature curves provided in the technical datasheet.
What is the maximum recommended load during cryogenic operation?
The 100 g load rating applies across the full temperature range (1.4 K–400 K); however, dynamic loads exceeding 5 g should be avoided below 4 K to prevent piezo stack depoling.
Are custom cable lengths or connector types available?
Yes—custom phosphor bronze cabling (up to 1 m) and alternative feedthrough configurations (e.g., SMA, LEMO) can be ordered under OEM agreement.
