Abstract :
Force realization system and device We report the characterization of mechanical properties of a flux-quantum force device, which is designed and fabricated to trap superconducting flux quantums for generating pico-newton standard forces, at variable temperature. Using our scanning fiber imaging technique we micro-positioned an optic fiber onto the target position of the device and measured the device´s vibration to obtain a resonance frequency of 1167 Hz at 4.5 K and a spring constant of 2×10-4 N/m at room temperature.
