Quantum Design PPMS DynaCool Cryogen-free Physical Property Measurement System

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.

    Spectroscopy and FMR/CryoFMR

    Raman & Luminescence Spectroscopy System

    Quantum Design's new Spectroscopy System combines Raman and Photo-Luminescence spectroscopy with optical sample imaging in the variable temperature and magnetic field environment of the PPMS. Using this "turn-key" system, gaseous, liquid and solid materials, in bulk or thin film form, may be investigated. Raman spectroscopy is a non-destructive spectroscopic technique used to identify and explore vibrational, rotational, and other excitation modes in a sample. Raman spectroscopy is commonly used to identify crystalline materials by measuring their specific Raman "fingerprint." This is done by measuring the inelastic scattering of light. In crystalline samples, the inelastic gain or loss of energy produces narrow discrete peaks known as Stokes and Anti-Stokes peaks, respectively. Glasses, in contrast, have broad vibrational spectra that in turn give rise to broad Raman spectra. When using the versatile PPMS Spectroscopy System, the study of spin-lattice coupling in strongly correlated oxides as a function of temperature and magnetic field is made easy through the highly automated MultiVu interface.

    Compact Imaging Spectrograph
    (Andor Shamrock 193i Spectrograph with iVac 316 CCD)

    Quantum Design now adds in-situ structural and chemical spectra analysis to PPMS materials characterization measurements at low temperature and high magnetic fields. This ability answers a growing demand in the research community. Offering a wide range of modular interfaces that feature cage system couplers, Quantum Design offers endlessly configurable connections between the Compact Imaging Spectrograph and the PPMS Optical Multi-Function Probe (OMFP). The spectrograph's "wide aperture" slit opens the door to a single set up with the OMFP to image the sample, while also allowing spectral information collection through the same optical path from the microscope.

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.
