Room and Low-Temperature Performance for a Sub-Attofarad Capacitance Sensor for Precision Measurements, Including Applications in Gravitational Wave Detectors
We describe the design principles, fabrication, and characterization of a precision AC capacitance sensor with a measured 0.33 aF/rtHz short term sensitivity, at 118 kHz bridge resonance frequency and at 1 Hz Fourier measurement frequency.
