A fifty-fold improvement of thermal noise limited inertial sensitivity by operating at cryogenic temperatures

Joris Vincent van Heijningen

A vacuum compatible cryogenic accelerometer is presented which will reach $<0.5$ p$g$ Hz${}^{-1/2}$ sensitivity from 1 mHz to 10 Hz with a maximum sensitivity of 10 f$g$ Hz${}^{-1/2}$…
