Overview
The Quantum Design TeslatronPT Plus is an open-architecture, helium-free cryogenic measurement system engineered for high-precision magnetic and electrical transport characterization under extreme low-temperature and high-magnetic-field conditions. Building upon the proven TeslatronPT platform, the Plus variant integrates a next-generation superconducting magnet with Nb₃Sn windings, enabling ultra-low hysteresis, suppressed flux jumping at low fields, and enhanced field homogeneity. Its core architecture follows a modular, instrument-agnostic design philosophy—supporting seamless integration of third-party metrology hardware while maintaining full thermal and electromagnetic isolation between sample space and cooling circuits. The system operates across a continuous temperature range from <1.5 K to 300 K, with magnetic field options spanning 6–1–1 T vector rotation, 8 T, 12 T, and 14 T vertical configurations. Designed explicitly for quantum materials research, topological insulators, 2D heterostructures, and correlated electron systems, the TeslatronPT Plus delivers reproducible, time-stamped, traceable data essential for peer-reviewed publication and regulatory-compliant lab workflows.
Key Features
- Helium-free superconducting magnet with Nb₃Sn coil technology—optimized for minimal remanent field and thermal stability below 2 K
- Open optical architecture featuring 128 SMA feedthroughs via customizable secondary insert, supporting high-channel-count optoelectronic and microwave measurements
- Automated cooldown and sample exchange workflows guided by step-by-step UI prompts—reducing operator dependency and procedural variability
- Browser-based oi.DECS control environment with RESTful API access, real-time telemetry, and role-based user permissions
- Thermally isolated sample chamber (50 mm diameter) with static exchange gas or high-vacuum operation modes
- Standard sample probe cooling time: <2 hours from ambient to <2 K; temperature stability: ±50 mK over 24-hour acquisition windows
Sample Compatibility & Compliance
The TeslatronPT Plus accommodates diverse sample geometries—including chip-scale devices, bulk crystals, thin films, and microfabricated Hall bars—via standardized mounting interfaces (LCC20, LCC40, DIL16). Sample orientation supports both parallel and perpendicular alignment relative to the applied magnetic field vector. All electrical signal paths are routed through low-noise interface boxes (IsoSwitch, MultiSwitch, SampleProtect), featuring configurable grounding schemes and driven-guard triaxial cabling options to preserve signal integrity in sub-nV/√Hz regimes. The system complies with ISO/IEC 17025 requirements for measurement uncertainty reporting and supports audit-ready data provenance when deployed in GLP/GMP environments. Time-synchronized metadata capture—including timestamped temperature, field, and instrument status—is natively embedded in all exported datasets per IEEE 1584–2022 metadata standards.
Software & Data Management
oi.DECS serves as the unified software backbone, providing cross-platform browser access to system control, experiment orchestration, and real-time visualization. It includes JupyterHub-hosted Python environments preconfigured with QCoDeS drivers, enabling scriptable measurement sequences, custom calibration routines, and automated error handling. Measurement templates are editable via web UI or version-controlled Git repositories. Data acquisition is synchronized across Lake Shore M81 (multi-channel DC/AC transport) and M91 (high-speed Hall analysis) instruments, with latency-compensated triggering and hardware-level source-measure synchronization. Grafana dashboards deliver live plotting of multi-parameter traces (B, T, Rxx, Rxy, dI/dV), with export options in HDF5, CSV, and MAT formats—all preserving hierarchical metadata trees compliant with FAIR (Findable, Accessible, Interoperable, Reusable) principles. Audit trails, user login logs, and configuration change history are retained for FDA 21 CFR Part 11–aligned validation.
Applications
- Quantum oscillation studies (Shubnikov–de Haas, de Haas–van Alphen) requiring sub-mK thermal stability and field sweep reproducibility
- Low-carrier-density semiconductor characterization using fast Hall mapping (M91) with 100× throughput gain over conventional lock-in methods
- Non-linear transport and noise spectroscopy in mesoscopic devices, enabled by M81’s real-time sampling architecture and 100 kHz AC capability
- Magnetotransport anisotropy mapping via integrated vector magnet option—critical for spin-orbit coupled systems and skyrmion lattices
- In situ gate-tunable measurements with integrated cryogenic wiring solutions and electrostatic shielding protocols
FAQ
What magnetic field configurations are available on the TeslatronPT Plus?
The system offers fixed vertical fields of 8 T, 12 T, and 14 T, as well as a 6–1–1 T vector magnet option enabling arbitrary field orientation in 3D space.
Can I integrate non-Lake Shore instrumentation into the oi.DECS framework?
Yes—oi.DECS provides documented QCoDeS-compatible driver APIs and generic SCPI/HTTP endpoints for third-party instruments, including Keithley SMUs, Zurich Instruments HF2LI, and Keysight B1500A.
Is vacuum or exchange gas operation mandatory for all measurements?
No—the system supports dual-mode sample environments: high-vacuum (<10⁻⁶ mbar) for ultra-low thermal load applications, or He exchange gas for rapid thermal equilibration and improved temperature uniformity.
How does the TeslatronPT Plus ensure data traceability for regulated research environments?
All measurements include immutable timestamps, instrument firmware versions, calibration file hashes, and user authentication tokens—enabling full chain-of-custody reconstruction required under ISO 17025 and GLP audit protocols.
What level of technical support is provided post-installation?
Quantum Design offers remote diagnostics, annual calibration verification, on-site application engineering visits, and access to a secure customer portal with firmware updates, driver libraries, and SOP documentation.
