PPMS® DynaCool™

Quantum Design, Inc. PPMS® DynaCool™

The popular Physical Property Measurement System (PPMS) from Quantum Design is now available in a truly cryogen-free package. The PPMS DynaCool, Quantum Design’s latest development effort, 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. Utilizing 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!

PPMS DynaCool Features:

Integrated DynaCool Measurement Applications

PPMS Family Options Compatibility Table

  • Low Temperature Stages

  • Thermal Measurements

  • Magnetometry

  • Electro-Transport

  • High Pressure

Helium-3 Refrigerator Option

  • Continuous operation down to 0.5 K
  • Compatible with Heat Capacity, Electrical Transport and DC Resistivity measurements

Dilution Refrigerator Option

  • Continuous operation from 4 K down to 50 mK
  • Compatible with Heat Capacity and Electrical Transport measurements

Heat Capacity Option

  • Completely automated relaxation technique from 1.8 - 400 K

Thermal Transport Option

AC Resistivity ρ

  • Measured by using precision DSP current source and phase-sensitive voltage detection.

Thermal Conductivity κ

  • Measured by applying heat from the heater shoe in order to create a user-specified temperature differential between the two thermometer shoes.

Seebeck Coefficient α

  • Measured by creating a specified temperature drop between the two thermometer shoes - just as it does to measure thermal conductivity. However, for Seebeck coefficient the voltage drop created between the thermometer shoes is also monitored.

Thermoelectric Figure of Merit ZT

  • Determined here simply as the algebraic combination α2T /(κρ) of the three measured quantities - thermal conductivity, Seebeck coefficient, and AC electrical resistivity.
