Room Temperature RUS and Sample Preparation

We use the RUS system by Dynamic Resonance Systems to make measurements of resonant frequencies and elastic constants of new materials. Current interests include metallic glasses, thermoelectric materials, and composite materials. We are also continually working on improving the design of the system. This work includes redesigning the transducer housings and implementing an xy-translation stage to move the bottom transducer housing to slightly reposition the sample during a measurement. This work, along with sample preparation, is done with the help of the following equipment:

DRS Q9000 RUS System: With an RUS stage used for centimeter sized samples and one for millimeter sized samples. This system is used to make RUS measurements for determination of elastic constants and for non-destructive testing and evaluation purposes.
Anatech Hummer 6.2 Sputtering System: Used to etch, clean, and sputter-coat transducer housings made in our machine shop for use on the room temperature RUS apparatus.
Struers RotoForce/RotoPol Polishing System: Used to polish samples to the exact tolerances required for precision RUS measurements.
Low-Speed Diamond Saw: Used to cut soft metals, hard ceramics, brittle and single crystal samples into parallelepipeds and other shapes useful for RUS work and for measurements in our PPMS (resistivity, hall-effect, torque magnetometry, specific heat, magnetization).
Laue X-Ray System: Used for alignment of single crystal samples before cutting and polishing.
