摘要：
The low-noise read-out electronics for the rhenium experiment is presented. We have built three source followers with two matched J-FET in cascode configuration. These are cooled at about 150 K in a thermally shielded box in the inner vacuum chamber of the dilution cryostat. The output is forwarded to a noise-matched amplifier at room temperature. In the operating conditions, the overall voltage noise density ranges between 0.8 and 1.1 nV/Hz(-1/2) at 1 kHz. The 1/f noise contributes with an excess noise lower than 3 nV/Hz(-1/2) at 1 Hz.
