title: A (3)he-cooled bolometer for the far infrared.
abstract: A germanium bolometer cooled to 0.37 K by liquid (3)He is described. This detector has a NEP of about 3 x 10(-14) W /Hz(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.
