Quantum Design 14T "Blue" PPMS Details

Clark Hall D22 (Primary Staff: Steve Kriske; Secondary Staff: Jon Shu)

The 14 Tesla physical property measurement system is similar to the 9 Tesla "Red" PPMS with a few key additions:

• Maximum 14 Tesla magnetic field
• Cryopump for measurements in vacuum (10^-5 torr)
• Thermal Transport measurements (thermal conductivity, Seebeck Effect)
• Low-vibration cryogen system
• Helium-3 refrigerator for cooling to ~400 mK
• Custom probe with up to 16 contacts and electrical isolation from chamber

In addition to the base system and Quantum Design measurement options, the system is equipped with several lock-in amplifiers for measurements through the custom probe or other connections.
