The Quantum Transport Laboratory (QTL) maintains a Quantum Design Physical Property Measurement System (PPMS) for characterization of electrical, thermal, transport, and magnetic properties of materials down to cryogenic temperatures.  The PPMS provides precise and continuous temperature control from 1.9K to 400K and is equipped with a 9-Tesla superconducting magnet for work at high magnetic fields.  Installed accessories include DC resistivity, high vacuum (<10-5 Torr) cryopump operation, horizontal sample rotation, and a user-modifiable multifunction probe for custom sample assemblies.  A Keithley 2636A Dual-channel system Sourcemeter  is available as well as a BNC breakout box that allows direct electrical access to connections on sample pucks and the useer bridge of the Model 6000 controller.  Experimental control is provided by MultiVu, Labview, or Python software packages.  A Cryomech PT410 Helium reliquifier allows continuous operation with closed-cycle cryogen recovery. 

In addition to the PPMS, the QTL provides technical consulting and instructs students in cryogenic techniques.
