Dilatometer for thermal expansion & magnetostriction

Based on our miniature interferometer, we demonstrate the thermal expansion of Cu, Ti and Terfenol-D, as well as magnetostriction data on Terfenol-D and Invar over a wide range of cryogenic temperatures as well as in high magnetic fields. The cell effect is minimized by a suitable choice of materials, and compensated for by using a second reference beam in addition to the sample beam. The difference between both signals allows for the calculation of the thermal or magnetic strain. The measured resolution in our first demonstration reaches 1 nm on mm-sized samples, while the sensor resolution of 1 pm could reduce this down to 1 ppb.

In situ measurements of irradiation-induced creep on amorphous micropillars

S. Özerinç and his colleagues at the University of Illinois at Urbana-Champaign have developed an apparatus for measuring irradiation induced damage and stress on the nanometer scale. Using attocube's ECS3030 as well as the FPS3010 interferometer, the system can measure in situ the deformation of mechanically stressed micro-pillars, during which the pillars are irradiated with heavy MeV ions. The apparatus provides a new and effective approach to accelerate the evaluation of promising materials for future nuclear power plant applications.

The FPS3010 mastered the independently performed calibration test by the PTB: the National Metrology Institute of Germany. Even under changing temperature, pressure and humidity, the sensor tracked a target position with a stunning accuracy better than 140 nm per meter (0.14 ppm).

Rely on the international standard (ISO) & use the FPS3010 to efficiently and precisely locate your device.
