Quantum Design PPMS DynaCool

Quantum Design PPMS DynaCool

Cryogen-free Physical Property Measurement System

The PPMS DynaCool, uses a single two-stage Pulse Tube cooler to cool both the superconducting magnet and the temperature control system, providing a low vibration environment for sample measurements.

Utilising a new approach to cryocooler equipment design, the PPMS DynaCool employs a unique 4He-based gas flow control system that gives you the rapid temperature cycling and accurate temperature control that you have come to expect from a PPMS.

The PPMS DynaCool also comes standard with an integrated Cryopump used to pump out the sample space to a vacuum of < 10-4 Torr.  This makes the PPMS DynaCool compatible with all the available options, or any other user-designed experiments, right out of the box.

    NanOsc FMR Spectrometers
    The CryoFMR spectrometer is a plug and play system that allows broadband CPW-FMR characterisation with lock-in capability. It includes its own RF frequency source as well as lock-in detection module, so that the only parts required to conduct an experiment are a computer for software control and a PPMS platform. Temperature range: 4 K to 400 K. Frequency Range 2 to 17 GHz.

    Measures relative expansion (dilation) and first derivative (coefficient of expansion) with respect to temperature and field, with sub-angstrom sensitivity. This is accomplished using a differential ratiometric capacitance bridge, operating at 2.340 kHz, which offers high sensitivity and dynamic range.

    Optics

    Optical Multi-Function Probe (OMFP)

    The newly designed Optical Multi-Function Probe (OMFP) offers unprecedented flexibility and versatility that allows you to conduct photonic, quantum optics and correlative microscopy experiments within the variable temperature and magnetic field environments of the PPMS, DynaCool and VersaLab. The OMFP probe features a room temperature “head” with multiple access ports and integrated optical breadboard for mounting optical components such as spherical and achromatic lenses, turning mirrors, filters, diffusers, beam splitters, prisms, waveplates, fiber bundles and electrical wiring. The open modular design of the probe head provides easy access to the axial ports and connectors which can be configured to route electrical, single fibres, fibre bundles and miniature waveguides to the sample space. In addition, a central optical access port allows free-beam optics experiments in the cryostat. A 0.5 in. standard optical thread mount makes aligning and focusing lens assemblies fast and easy.
