Abstract

A germanium bolometer cooled to 0.37 K by liquid ³He is described. This detector has a NEP of about $3\times {10}^{-14}\text{W}/{\text{Hz}}^{\frac{1}{2}}$, which is more than three decades greater sensitivity than the Golay cell. The factors that determine the sensitivity of the detector are discussed.
