Oxford Instruments NanoScience has launched the TeslatronPT Plus, an open-architecture low-temperature measurement system designed for advanced electrical transport measurements in high magnetic fields. The system integrates Lake Shore’s flagship measurement instrumentation with an upgraded TeslatronPT cryomagnetic platform, featuring Cryofree® superconducting magnets and automated workflows for system cool-down and sample exchange. Its open architecture allows researchers to use Python programming via Jupyter Notebook, Grafana for real-time data visualisation, and the QCoDeS driver framework for third-party instrument integration.
The TeslatronPT Plus supports a wide range of measurements, including low and high resistance, Hall effect in Hall bar and van der Pauw geometries, and I-V characterisation. Key features include fine filament Nb₃Sn superconducting wire for minimal field hysteresis and flux jumping, an integrated variable temperature insert (VTI) with a large sample space, and a static exchange gas cooling system. The system’s oi.DECS software provides browser-based control of temperature and magnetic fields, enabling remote operation and automated workflows for consistent experimental results.
The oi.DECS Measurement Extension offers a full measurement solution with a dedicated server, including JupyterHub for Python programming, editable measurement templates, and seamless integration of third-party instruments. Data acquisition and visualisation are handled by Grafana, which provides secure access to real-time, time-stamped data for correlated analysis. This open-architecture approach ensures flexibility and scalability, allowing researchers to customise their experimental setups and integrate existing laboratory assets.
Measurement hardware options include Lake Shore’s M81 Synchronous Source Measure System for low-level electrical transport measurements and the M91 FastHall™ Measurement Controller for complete Hall analysis. The M81 combines DC precision with AC detection sensitivity up to 100 kHz, while the M91 improves accuracy by minimising thermal drift and is up to 100× faster for low-mobility materials. These instruments are fully integrated with the TeslatronPT Plus’s open-architecture software, ensuring optimal performance and ease of use.
The TeslatronPT Plus is designed to simplify measurement processes, reduce setup time, and provide a flexible, scalable solution for advanced materials research. Its combination of Cryofree® technology, open-source software, and third-party instrument compatibility makes it a practical tool for researchers in fundamental materials physics.
