Capacitance Dilatometry in Pulsed Fields

Capacitance dilatometers possess a parallel plate capacitor with a one stationary plate, and one moveable plate. When the sample length changes, it moves the moveable plate, which in turn changes the gap between the plates. The capacitance is inversely proportional to the gap. Changes in length of 10 pyrometers can be detected (Schmiedeshoff et al., Rev. Sci. Instrum. 77, 123907 (2006)J. J. Neumeier et al., Rev. Sci. Instrum. 79, 033903 (2008), Kuechler et a., Rev. Sci. Instrum. 83, 095102 (2012)).
