A Comprehensive Physical Property Measurement System Without Liquid Helium

A Comprehensive Physical Property Measurement System Without Liquid Helium
The completely liquid helium free comprehensive physical property measurement system is the second measurement system launched after the multifunctional vibrating sample magnetometer VersaLab (3T, 50K-400K), which does not require any refrigerant such as liquid helium.
PPMS DynaCool remains a PPMS system in terms of functionality, with all the measurement functions of previous PPMS systems. However, due to the internal optimization design of its Dewar, the PPMS DynaCool system does not require any refrigerant such as liquid helium. The system uses a two-stage pulse tube cooler to provide an ultra-low vibration low-temperature environment for superconducting magnets and sample measurements. And the system host has already integrated a cold pump that generates<10-4 Torr high vacuum, making PPMS DynaCool compatible with all related option upgrades.
Application field:
Magnetic, thermal, and electrical measurements (including but not limited to AC/DC resistivity, magnetoresistance, differential resistance, Hall coefficient, volt ampere characteristics, critical current, AC magnetization, hysteresis loop, thermomagnetic curve, specific heat, thermoelectric effect, Seebeck coefficient, thermal conductivity, expansion coefficient, and morphology characterization).
