Abstract

In this paper we present the design, assembly and characterization of a low temperature sample rotation system based upon a commercial, electrically controlled piezo rotator. This rotation system allows for samples to be rotated through angles greater than 100° within the 39 mm sample space of our Kelvinox100 dilution refrigerator, whilst maintaining a temperature below 100 mK. Preliminary low temperature transport measurements on a 2DEG sample show that quantum effects can be clearly observed whilst the rotator is active.
