Abstract This paper describes a transversely suspended accelerometer (TSA) designed to measure acceleration at low frequency with high sensitivity in the vicinity of a strong magnetic field. The TSA is a simple diffraction-limited imagepositioning device capable of measuring constant (DC) and variable (AC) acceleration simultaneously in two perpendicular directions. It has a resonant frequency of 5.2 Hz (33 rad/s), a range of 0 to 20 mG, a sensitivity of 25 μG and a spatial resolution better than one measurement per four cubic millimeters. Steps taken to design, calibrate and test the TSA are described, and a brief description of one potential application for using the device as a gravitometer is presented.
